Some of the reasons I don't spray pesticides ...

My pleasure. The wonderful thing about gardening forums is that there are others with common interests, who derive enjoyment from gardening in similar ways. I'm a fan of both the flora and the fauna.

Your organic greenhouse sounded great. :-)

Hang on there! I'm actually proactive in a natural kind of way. I'm new to fruit trees, but have been gardening organically for more decades than I care to admit. My garden usually does quite well with a minimum of the most benign possible intervention.

My plums are not great this year, true, but most other things have done fabulously well, despite, or because of, the cool, wet growing season. Why not the plums? If I can figure out what went wrong, I can take measures to try to prevent it from happening again.

Reading everyone's suggestions pointed up causes that weren't uppermost in my mind. For instance, Paghat mentioned nearby farms. I don't think they're close enough, but it reminded me that there's is a huge, overgrown vacant lot 100 yards away that was partially bulldozed when a structure was removed. The property has some apple and crabapple trees in horrible condition, as well as all kinds of berry brambles in bad shape. The destruction of their habitat might have lead to some of the bad bugs migrating.

There's an old Italian guy just up the road who had a stroke about 5 years ago and can't maintain his fruit trees. His fruit probably rots on the ground.

Both of these factors could explain some of the problem.

The weather has also affected the insects. Populations vary with every growing season. Every year I try to spot as many of the bugs as I can. This year there have been more sawflies, plant bugs, plum and black vine curculios, pear slugs, a few types of hoppers, and ladybugs than usual. I've seen fewer varieties of butterflies, and fewer individuals ... even cabbage whites, but there are a fair number of moths of various kinds ... including fruit moths, and Iris borers. I guess it's my own fault for having so many night flowering plants. ;-) Other insect numbers and diversity seem to be about normal for here, though maturity cycles are delayed for most. I look for population patterns.

My attitude is that that if I maintain good gardening practises, and take the necessary precautions, next year will be better for the plum. There are things that I can do, but other things are beyond my control.

I'm within spitting distance of a golf course, and they spray gawd knows what. Several of my neighbours hire companies to spray toxics so that their lawns will be weed and grub free. Luckily, some others are too cheap, and some have even come around to a more organic approach after seeing my garden.

I keep a photo journal of the garden every year. I'll be putting August up in the next few days, but here's July:

Don't know about Orkin, but I will put in a good word for some local pest control guys. We had a tiny baby at home and *several* yellowjacket nests near the front and side porches. Something *had* to be done.

Called a local pest control guy (not someone from the big chains). Watched him through the front window while he smoked the nests, raked them up and into heavy plastic bags, sealed them up and hauled them away. It was worth every penny I paid him just to see that. (He remarked how unusual is was to see so many wasp nests so close together.) Problem solved; other than a few stragglers the next day, they were gone.

Now, I'm sure the guys at the big chains would be pushing to get you set up as a regular customer for all kinds of preventative pesticide applications. (That was the case when I called the company which starts with T and ends in X.) But not every possible solution involves massive amounts of pesticides...

Paghat, have you ever written a brief response? Oh yes, I did see one once. Of course you quoted several pages before that response, so the effect was the same.

Now a report on the yellowjackets. I actually called Terminex. The responder donned his protective clothing, located the nest, "froze" it with about a 5 second burst of something, took down the nest and carted it away. He informed me that the yellowjackets would be angry the rest of the day and would die overnight. Apparently they need the nest.

I went out this morning and there wasn't a yellowjacket to be found anywhere in the vicinity.

So - problem solved, no massive pesticide application, and you can kill them without waiting for evening.

Seems to me you doth protest too much :-).

I am not going to let you have the last word on this.

I asked you for specific information on all these university reports about the wonders of fruit grown organically, and you ignore the issue. Give me a document location on the web that backs up your contention of superior tasting fruit from organic orchards.

I have not said that organic prevention is totally worthless. I don't rely on spraying insecticides to do the entire job. I use sticky traps, wasp traps, and even nets around the fruit to keep the bugs from attacking. My only contention is that for the nastier bugs, organic sprays have not yet reached a state of the art where they can do the job. So if it comes to deciding between spraying and losing fruit, I'll choose the later. Also, you have not mentioned spraying for fungicides and organic ways to

prevent those problems. I have used organic sprays, like Rotenone, in the past, and

they just don't do the job. Maybe in your part of the country, you don't have the problems with Apple Maggots, etc. like we have in the Midwest. I would be surprised if you don't have some kind of pesky bugs, but not knowing about Washington State, I can't judge the effectiveness of organic prevention.

I didn't say organic gardening was a cult, but the way you try and push it down our throats gives the appearance of a cult (like this is the ONLY truth, and all gardening nonbelievers will not get into gardener's heaven). Also, your snide remarks against

not believers makes me think that you follow organic gardening like a cult. I know some organic gardeners, and none of them threatens me with fire and brimstone if I don't mend my ways.

Show me actual facts, and real documentation, and proof that organic gardening will work in the really difficult cases, and then I am ready to switch over.

Excuse me, but organic growers are known for growing varieties which are disease and pest resistant. It's part of the holistic approach to organic growing. I have only tasted bad 'Delicious' apples when they were woody or lay around too long, other than that, they are superior in taste, IMO, to many other varieties of eating apples.

You are also incorrect about "profit motive" since many organic farms are very small, and sell their produce at farmers markets, not on grocery shelves. I have news, the grocery stores hike up the prices, not the growers. For instance, bananas. If you see the word organic on a banana, it's generally a useless term. Bananas normally never need pesticides to produce. In the case of organic bananas, they are grown without the use of synthetic fertilizers. The store hikes up the price because they are in their special organic section. I shop either at the farmers market, or Whole Foods Market and their prices are maybe 5% more than commercially grown foods, which use pesticides and synthetic fertilizers. I know because Whole Foods Market also sells conventionally grown fruits and vegetables, so I see the price side by side in many cases.

Oh, yes, people indeed DO get cancer from the chemicals being used. But since the toxin developers are in bed with politicians, not much will be done about it, at least till we get a different administration. AND, in one month, to take this to another level, you'll once again be able to buy an AK47.

Good morning sunshine.

Provide a REAL citation for that fatuous chemical industry propoganda slogan, the blurting out of which indicates nothing but that you're a hopeless case. You demanded citations from me & got them though obviously you never really wanted them & still could not care any less about the truth. You persist in this kind of merely political myth-making -- still being that suicidal nutcase who no matter how many reasons to live he is given, always has one more excuse why you should even so shoot yourself in the head, taking down as many others as with you as you can.

Your knowledge of the causes of famine is way down there in the zero range with much else you've been mistaken about this week. Get this if you get nothing else:

Chemical dependency leads to environmental degradation leads to famine. Organic farming is sustainable.

I will follow up with my usual complete overview, but if you're capable of learning, all you need is the above two sentences to be much less foolish than you've been up to now.

In some regions starvation has resulted because the best land has been turned over to coffee bean production or sugar cane or some similar crop to be shipped to the west, all land & profits gained by the land belonging to a ruling wealthy minority, & no aerable land is available to peasants. In other places it is due to patterns of drought & cataclysmic climate changes such as the expansion of the Sahara. In others it is due exclusively to warfare or to scorched-earth campaigns. In others it is due to concentrations of populations due to migration to finite areas, resulting from drought & desert expansion or even more commonly from warfare. In the distant past there have been famines caused by dependency on single crops & those single crops became diseased, & there is some worry that this may recur in the future due to agribusiness's reliance on decreasing numbers of species & strains of those species. In India which many years ago undertook an unfortunate transition toward chemical dependency for nationalistic reasons has increased the amount of land that can no longer be farmed at all because toxic salts have built up from continuous use of chemical boosters & pesticides -- this land is being abandoned by rich agriculturalists but it is no longer useful for peasants to farm.

So there are many causes of famine.

Organic farming has never been one of them.

As reported by the Soil Association in SOIL: The Importance & Protection of Living Soil (2001), chemical & biotech dependent crops have been leaching soil to death, & are will lead to famine. They recommend a return, in both Europe & Africa, to organic farming methods which are the only sustainable methods in the long run, besides producing a higher quality of produce in the short run.

Even if SOME crops could be increased with chemical dependency, that issue has no relevance in improverished parts of the globe which cannot afford the chemicals. Whereas improving upon their own traditional methods can increase crop yields 200 to 300% without resorting to chemicals. While chemical fertilizers & pesticides deplete soil over time & kill its essential living microorganisms, improving organic methods increases soil richness & increases microorganism population, hence SUSTAINABLE increases in crop production WITHOUT chemicals.

While the CHEMICAL and BIOTECH (GM) companies have undertaken a world-wide campaign to promote the idea that organic growers in Europe & the USA are "criminal" for turning more & more to organic farming, because they could otherwise be growing much more chemical-dependent crops & send the excess to famine-stricken countries. This of course is completely fatuous since growers in the west can even be paid to grow NOTHING due to overproduction driving costs down. At any hour, this very hour, world hunger would end if all it took was to distribute more food from the west to countries where drought or warfare or peasant lack of access to aerable land has caused starvation. Blaming organic gardening for any of it is on the surface completely loony -- you swallowed it because you already convinced yourself of a lie before someone handed you a greater lie to reinforce your first one.

The reality is that organic farming for orchard crops & many annuyal crops produces the same or more produce than chemical dependent farming, does so more cheaply, in a manner that protects the soil for future crops. Even those annual crops that CAN be increased in yield with chemical dependency deplete soil at such a rapid rate that land is soon depleted; in Brazil the answer to this problem is to take a load of chemicals deeper into the jungle, slash & burn so that nothing of the jungle remains, & start over with a very few years of high-yield crops ending in land that can never be used again. The chemical biotech industrialists expertly trumpet "High Yield Non-Organic Farming" with no underlying science to support what is purely a POLITICAL campaign so that a very few biotech & chemical giants can control the production of food in third-world countries.

In villages where traditional methods are still practiced, yields are low but meet the local needs. When it becomes necessary to buy chemical fertilizers & pesticides or special herbicide-resistant grains, the expectation is not to feed people better but to have a salable excess beyond local need; unfortunately, even if "greed is good" it is not good in this situation. Profitable excess never happens in regions where the main feature to overcome is limited water resources. Even in the fewer cases where profitable short-range profits do occur from momentary high yelds, the soil is rapidly depleted & the short-range gain ends in long-run losses -- & famine. By then the soil may take years to restore if it ever is restored, & the interuption in the use of traditional methods results in extinction of sustainable seed strains, making it difficult to return to the sustainable organic methods.

As oil-based products skyrocket in price, chemical-dependent crops become less & less economically feasible. There are no chemical-dependent farming methods that have ever been shown to increase production in regions with limited water resources, & if the Hopi became non-organic farmers tomorrow, their corn strains would soon become extinct. And indeed, one of Monsanto's great goals is to drive desert-hardy, fertile, & sustainable corn crop strains to extinction, in favor of their own seed alleged to provide super-crops (impossible in desert conditions) which produce crops that are sterile so that no percentage of the seed can be held back for future crops. The purpose is NOT being to feed starving people but to make starving people perpetually dependent on agribusiness for their seed. No cash for the next year's seed, say hello to famine.

The governments of Kenya , Uganda & Tanzsania, in order to fight famine by the best means, have undertaken nations-wide campaigns to re-establish & upgrade sustainable organic farming methods. The chemical companies' successful intrusions to do away with organic farming practices have been a direct contributor to the destruction of croplands.

The BETTER system would have been, & still is, to share advances in organic methods that may improve on localized primitive agricultural systems without doing away with those traditional systems. Just one example: the use of compost toilets can make an entire village a source of organic fertilizer, breaking the cycle of dependency on chemical fertilizer to prop up depleted soils; the use of the organic compost will reverse soil depletion caused by the use of chemicals, thus resulting in better more sustainable produce. Every problem has an organic answer that in every case does indeed turn out to be the superior choice.

some random quotes from others:

"If you apply organic principles and you take care of the soil in the proper way, you can very much increase your yield. This is the most sustainable way, not only for the export market but also for food security." [Thomas Cierpka, executive director, International Federation of Organic Agricultural Movements]

"Contrary to what its opponents sometimes suggest, organic farming is not in the least anti-science and looks to biological science particularly for assistance in dealing with fertility, crop pests and diseases. Although research institutes in Europe have done much pioneering work and several new centres are coming on-stream, Cuba probably has more scientific resources employed in organic farming research than the rest of the world combined. It had to - otherwise there could have been famine back in the '90s when it was largely abandoned by its major supporter, the USSR." [Grace Maher, Agriculture & the World Summit on Sustainable Development, Sept 2002]

"Output levels in organic farming can match and exceed that of chemical farming - eg see Teagasc, Johnstown Castle, recent report. And where they don't, decent research funds would undoubtedly raise productivity. There are many more studies - I'd be glad to cite them if requested. But, at a practical level, take even my own humble case; I grow garlic, organically, about 40,000 plants, and get yields over 100% more than the European commercial average. Furthermore, a study I made on potatoes shows, remarkably, that modern agriculture still hasn't equalled the output levels achieved in Ireland before the 1840's Famine. .... Chemical farming has left us a legacy of a degraded environment, mountains and lakes of surplus produce, factory farming of animals, decreased employment and profits in agriculture, and, of course, food contamination. Directly add the costs of these effects to our conventional food (which we pay for indirectly anyway) and we'll see the real price of food. The men in white coats are scraping the bottom of the barrel for arguments to bolster a losing case. Again, a pro-GM scientist (Conference on GM food, Skibbereen, Feb '99 ) said - almost with a giggle! -  that, 'organic potatoes are poisonous and you organic farmers here should throw them all away.'" [Jim O'Connor, Ireland, from a widely circulated letter in the Irish Times]

When I lived in California, perhaps one mile from my place there was an abandoned Red Delicious orchard. It kept pumping out, year after year, the sweetest apples I have ever eaten. They were too sweet, in fact (I much prefer the tart, complex northern varieties, such as Northern Spy or Liberty. And even when it comes to sweet apples, the Michigan Golden Delicious are superior to anything I have tried). No bugs, no blemishes, no spray, no irrigation (no rain for five months before harvest) or fertilization. Incredible. It would take minutes to go there and pick a bushel for the week (I am much the fruitarian in season, ten apples a day is not too much if they are at their top).

I didn't spray the cherry tree at all this year and the insect and brown rot loss wasn't that bad -- less than what I lost to the robins.

I live in Southern Minnesota (there's an oxymoron for ya) and the curcullios and apple maggots are awful here. I don't spray anything until after 100% petal drop out of respect for the bees; they're having a tough time here with the mites. I didn't spray any fungicides this year and it shows, but a little scab on the apples doesn't hurt anything. I stopped spraying in July (out of laziness) and was afraid the apple maggots would ruin everything, but diligent clean-up of fallen apples last year seems to have paid off. In the past, some years even with spraying the apple maggots have totally destroyed my crop.

I would love to get to where insects and disease could be controlled with just a dormant oil spray before the buds break, followed by Integrated Pest Management (with a sprayer of malathion standing by, unused, just in case of emergency.) I don't know if IPM works here or if the insect load is just too high. I think proper orchard hygiene, traps, and minimal spraying whenever the traps show a high insect population might be more effective and more ecological than prophylactic spraying every 10 days and every time it rains.

I never said they didn't grow these resistant fruit.

I think you should expand your horizons and start tasting more varieties of fruit.

I shop occasionally at Whole Foods Market and the markup is much greater than

5%. I see things like a bunch of organic carrots selling for two dollars, while the non-organic bunches are selling for one dollar. These growers are not stupid. If they see the fruit selling for higher prices, they would be remiss, if they didn't ask more for their harvest.

What's with you organic enthusiasts. Do you all believe the world is going to soon end? Pollution from our factories and vehicles is a much much greater threat than the pesticides being used. When we convert all our energy sources to solar, nuclear, etc., than I think we can worry about the pesticides.

Oh, so people in Africa are not starving and they are not having massive crop failures from weather and insects. Programs like National Geographic must be giving me some of that propaganda. Shame of them.

Your so-called documentation is worthless.

I prefer that you shoot yourself in the mouth.

Talk about propaganda!

I don't think I can learn anything from you. All you know is how to insult people.

You did not mention crop destruction by swarms of locusts, etc.

I'm not blaming organic gardening for anything other than a naive concept that it can completely control our pest problems.

Yes, its all a conspiracy to get us.

I see the opposite. In my garden centers, the organic stuff costs way more than the chemical stuff.

There's the same conspiracy theory again.

You accuse me of picking up e-colli laden fruit from under my trees, but you

are pushing the recycling of human waste, which in many cases contains a wealth of harmful bacteria, and I wouldn't trust composting to kill it all.

Why did they have a famine? Wasn't it because of some blight that wiped out their crops? Maybe the right chemicals would have saved more of their potatoes.

Organic farming and gardening is a fine goal to aim for, but there is still a need for chemicals to keep pests under control. Some places can rely more heavily on organic methods, but other's need the chemicals. In my case, a high priority for me is the very best tasting fruit with the least damage. I don't think I can go completely organic in today's world. If and when the organics are developed to do the job, I am ready to convert over. I don't like spraying these chemicals, but for now, there are no good alternatives.

Bob,

Try telling that to Rat Lady, who thinks everyone has the same environment as her Washington home. I believe Apple Maggots, for one, are predominantly found East of the Rocky Mountains.

Did you use an effective spray like Imidan? That one really works on apple maggots, but it is not available to the home orchardist anymore. If you can locate a supply of it (farmers can still get it), give it a try.

My experience is that by waiting too long between spraying, say over one month, problems develop. Most years I average about every three weeks. I missed one apple tree( Cox's Orange Pippen) on one of my three week cycles, and the tree is now showing signs of attack. The leaves are turning prematurely yellow with brown spots, and the fruit is being attacked. It may be a coincidence, but I suspect the pests found a window of opportunity.

So we're not supposed to take care of what we can, and eliminate toxic chemicals from our soils and foods? No, small market farmers can right now take care of it, and they are. The organic gardener/farmers are making money now, whereas the same can't be said for conventional/chemical using farmers. Plus their produce is higher quality; they aren't catering to the mass-shipping market, but tend to either direct sell or sell locally so they can grow produce that's actually bred to taste good, rather than withstand shipping. And finally, the produce is coming down in price, as more and more farmers enter the market. I welcome and celebrate it, and know that people who think like you are becoming fewer and fewer (thankfully).

I used a mixture of malathion EC and methoxyclor WP (I'll add captan or maneb in the spring next year). If I had seen actual signs of apple maggots, I would have sprayed diazanon in July and then switched back to malathion in August, and stop spraying in mid-August. I have a quart of diazanon 50 EC.

No, I didn't say that. It's putting organic farming way up there as the way to save the world. The concept is good, but the fanaticism is not called for.

Organic grown produce may have reduced traces of chemicals (that's why I wash all my purchases), but there is nothing about organics that makes the fruit taste any better, or hold up better in shipment. The organic stuff will spoil as quickly as the chemically grown stuff. However, you can change the genetics of a fruit, for example, to hold up better in shipping, like the Red Delicious Apple. Unfortunately, that can reduce the taste of the fruit. Properties like taste and holding ability for shipment are in the genes of the fruit. Organics does not change those! As I mentioned in earlier postings, organics growers are almost forced to select varieties which are inherently disease resistant, to get any results with the lower powered organic preventatives. Unfortunately, these fruits are not the very best tasting varieties. If you pick a particular apple, for example, and grow it organically and also chemically, I cannot see there being any difference in taste or long term storage abilities. I grow a William's Pride Apple which is disease resistant to fungicides, but I still have to spray it with insecticides. It is not a bad tasting apple, but doesn't compare to my other apples, like Honeycrisp or Ashmead Kernel. I will stick with the chemical sprays to grow my excellent tasting apples, until the organic people come up with a spray that can protect all varieties.

I still see double prices for organic grown produce at my local Jewel Food Store.

Yes, but these people have never tasted a really good apple.

------------- POPs found in all foods: wvlc.uwaterloo.ca/biology447/modules/ module5/Jepidemilologyarticle/pesticidesinfoodpdf.pdf [] Based on data from the US Food and Drug Administration, this article provides a brief overview of POPs residues in common foods in the United States food supply. The analysis focuses on 12 chemical compounds now targeted for an international phase out under the Stockholm Convention on POPs. The available information indicates that POPs residues are present in virtually all categories of foods, including baked goods, fruit, vegetables, meat, poultry, and dairy products. Residues of five or more persistent toxic chemicals in a single food item are not unusual, with the most commonly found POPs being the pesticides DDT (and its metabolites, such as DDE) and dieldrin. Estimated daily doses of dieldrin alone exceed US Environmental Protection Agency and US Agency for Toxic Substances Disease Control reference dose for children. Given the widespread occurrence of POPs in the food supply and the serious health risks associated with even extremely small levels of exposure, prevention of further food contamination must be a national health policy priority in every country. []

--------------------------------

In actual fact, they do. Here's why.

If someone in India dumped DDT into the ocean, how long do you think it would take to get to the Gulf of St. Lawrence? Would you believe less than 2 weeks? It's called The Grasshopper Effect

formatting link
and it's just one of the ways that toxics travel around the world. This is why DDT, which has been banned in NA since the 70's, is still found in the belugas of the St. Lawrence. This is why they constantly need to replenish the Peregrine Falcons in the wild release programs. Pesticides (and/or their breakdown products) that were used from the

40's to the 70's are still out there in the food chain.

Pesticides permeate every body of water on the planet and are highly detrimental to aquatic life:

formatting link
levels of DDT are between 1 and 10 ng/l in estuaries and coastal areas, and between 0.1 and 1 ng/l in the open sea (Kennish, 1994). While DDT concentrations in surface waters are largely controlled by the concentration of DDT in the atmosphere, the ocean serves as a sink for DDT (Iwata et al., 1993). [] In the Arctic, the highest concentrations of DDT in surface waters are reported near the Indigirka River in the East Siberian Sea (2.5 ng/l) and in the vicinity of the Ob' River in the Kara Sea (2 ng/l, Melnikov and Vlasov 1992). DDT in belugas generally ranges from 1 to 5 ug/g in the Alaskan and Canadian Arctic (Muir et al., 1990; Careau et al., 1992; Schantz et al., 1993). Note that these values are about 1 million times higher than DDT levels in seawater. An average of 58 ug/g was measured in belugas from the St. Lawrence estuary, a high value indicative of past heavy use of DDT as a pesticide in eastern Canada (Muir et al., 1990). New data indicate that the White Sea is similar to the St. Lawrence estuary, with a value of 64 ug/g (Muir and Norstrom, 1994). [] Once ingested, DDT and its metabolites accumulate in the fatty tissues of organisms. Today, birds and mammals continue to retain both DDD and DDE, in part from retention in fat, and in part from uptake of residual contamination. An important concern with DDT is that it becomes concentrated as it is transferred up the food chain. In an aquatic environment, DDT at a concentration of 0.001 to

0.01 ppb (- or m? check), results in a 0.1 ppm concentration in aquatic invertebrates, 0.2 to 2 ppm in fish, and 10 ppm in birds (Edwards, 1973). Because pesticide residues can be transferred to offspring through excretion in the egg, progeny may begin life with an elevated body burden of DDT. []

--------------------------------------- More about Belugas and pesticides:

in the 1rst half of the century was the probable cause for this population to dwindle from several thousand animals to the current estimate of 500. The failure of the population to recover might be due to contamination by organochlorine compounds, which are known to lead to reproductive failure and immunosuppression in domestic and laboratory animals and seals. [snip] Overall, St. Lawrence belugas might well represent the risk associated with long-term exposure to pollutants present in their environment and might be a good model to predict health problems that could emerge in highly exposed human populations over time.

-- Environ Health Perspect 103(Suppl 4):00-00 (1995)

---------------------------------- Organochlorine levels in whales tissue samples from Trent University:

formatting link
Pesticide Release Database from Environment Canada:
formatting link
Organochlorines, which are stable and vapour-forming, can be carried by air currents for long distances. Eventually they condense and are deposited on land and water, particularly in cold climatic regions. Oganochlorine residues have been detected in air, water, soil, sediment, fish, and birds global wide. They have also been found in remote areas, such as open oceans and polar regions. If they contaminate the food supply of animals, organochlorines become more concentrated as they move up through the food chain. For this reason, the highest levels of organochlorines are found in species at the top of the food chain: human beings, fish-eating birds, and marine mammals. []

POP's such as aldrine, dieldrine, endrine, chlordane, DDT, heptachlore, hexaclorobenzene, mirex, chlordecone, lindane, and toxaphene, build up in tissues.

---------------- wvlc.uwaterloo.ca/biology447/modules/ module5/Jepidemilologyarticle/pesticidesinfoodpdf.pdf All living organisms on Earth now carry measurable levels of POPs in their tissues. POPs have been found in sea mammals at levels high enough to qualify their bodies as hazardous waste under US law, and evidence of POPs contamination in human blood and breast milk has been documented worldwide. There is strong evidence that exposure to even miniscule amounts of POPs at critical periods of development? particularly in utero?can cause irreversible damage. The effects of such exposures may take years to develop, sometimes appearing first in the offspring of exposed parents. []

-----------------

As we are at the top of the food chain, humans get the most concentrated doses of contaminants. Among whales, the females are less toxic than the males. Studies revealed that the reason for this is that females release the toxins from their fatty tissues into their milk.

formatting link
It's the same for humans. There are also indications that, due to their interactions inside the body, pesticide cocktails can be more toxic than the same amount of a single pesticide.

---------------------------------- Oraganochlorines in human breast milk:

(as DDE, a breakdown products from DDT) also appeared in the fatty tissues of seals and Eskimos, far from any area of use, indicating that, because of its persistence, it was being transported for long distances in the atmosphere and then being washed from the atmosphere by rains. It also showed up in human breast milk at remarkably high concentrations -- so high that the milk couldn't legally be sold through interstate commerce if it were cow's milk! DDE is the most widespread contaminant in human milk around the world. When you think about it, human breast fed babies are way up there on the food chain, and are thus very susceptible to the effects of biomagnification and bioconcentration. For persistent compounds like DDT (or other persistent compounds, such as dioxins or PCB's -- see "POPs," below) human milk is the most contaminated of all human foods. Typically, concentrations of organochlorines (such as DDT) in human milk are 10 - 20 times higher than in cow's milk, and prevailing levels are often greater than those allowed in commercial food stuffs.

exposure to organochlorine pesticides has been documented by studies detecting these compounds in various human tissues, including breast milk. Consumption of contaminated food (including fish and shellfish) is a major route of human exposure to organochlorine pesticides. [] Organochlorine compounds tend to be stored in high-fat tissues within the body, but can be mobilized during lactation or starvation. Levels of some organochlorine compounds in human tissues in the United States do not appear to have declined, at least through the early 1980s. Examples include DDT in breast milk and dieldrin in adipose tissue (fat). []

Body stores of pesticide are also associated with breast cancer:

why is there that much pesticide in the environment? Who's using it all?

Trends in Pesticide Use: "One major environmental science text book asserts that the average US homeowner uses 2 - 6 times more pesticide per acre than do farmers."

will focus on farms, because farmers consume (that is, use) about 77% of all pesticides in the US. However, it is important to realize that the problem isn't all related to farm uses. It is estimated that about 10% of the land area in the US (including forests, lawns, etc.) is treated annually with pesticides. Home gardeners are often some of the most extravagant ? and sloppy ? users!) (One major environmental science text book asserts that the average US homeowner uses

2 - 6 times more pesticide per acre than do farmers.) In the US, the total pounds of pesticide active ingredients applied on farms increased 170% between 1964 and 1982 (the increase was 33 fold between 1945 and 1990). These figures related only to the agricultural sector. In evaluating these increases, it is important to remember the increased toxicity of pesticides; one pound of active ingredient for current products is many times greater than one pound for earlier generations of pesticides in terms of toxicity. One might think that this trend was driven by increasing agricultural acreage over this time? Recall, during this time, total acres under cultivation basically decreased , so the increase in pesticide use wasn't driven by increased agricultural acreage. []

So, obviously, more is less.

the US, an average of 1599 kg of pesticide are used for each hectare of cropland, that's 3525 lb per hectare. 1 hectare= approx. 2.5 acres, so that makes it about 1,410 lbs of pesticide per acre.

So if home gardeners are using just twice that amount, it comes to 2,820 lbs of pesticide per acre. If they all stopped using pesticides, it would be a significant amount not going into the environment.

No amount of pesticide will control the locust infestation plaguing parts of Africa today. And ... That good irrigation is what gets pesticides into the water table:

The evidence suggests that they ARE being misused. And the more they're misused, the less effective they'll be.

Probably because the pesticides are acting in your yard as well. They're easily airborne.

That is irrefutably true. :-)

For people who persist in spraying, IPM is the better way. Spraying can be cut in half using IPM methods. Better for the environment, the pocket book, and the back.

An entomologist, who works at the big research station near here developing IPM protocols for peaches, told me that the main reason for IPM is that bugs adapt too readily to pesticides. Pesticides work really well for a few years and then start to be less effective as the bugs adapt. The big worry is soon there won't be any pesticides that work. IPM strives to keep pesticide use to a minimum, so that when it is used, it works. The added bonus for growers is lower cost, and better yield.

IPM borrows from successful organic principles, such as predatory control, and the proper timing of applications. Now that the life cycles of pest insects are better understood, controls (natural or otherwise) can be tailored to be more effective.

That's why I try to learn about every single new bug, or problem, that I find. For instance, I found out the plum curculios like the cool, dampness and lack of sun in the middle of the tree. I checked my tree, and the plums on the outside, that get sunshine through most of the day are the healthiest. I think I need to prune my tree to get more light into the middle ... now all I have to do is learn more about proper plum tree pruning.
