Terry Coombs used improper usenet message composition style by unnecessarily full-quoting:
I think you're confusing herbicides and insecticides.
Herbicides have no designed or documented effects directly on insects as far as I know, apart from reducing potential pollen sources from flowering weeds.
Good thing about Roundup and other products that only contain glyphostate and no other harmful chemicals is that it is almost harmless to people and animals with normal usage. You could probably drink small quanties and have almost no effect. Maybe like a good dose of Exlax. You would think somthing that would kill almost all plant life would be very dangerous to people, but turns out it is one of the safest chemical grass and weed killers.
Why do you have your line-length set to 50-odd characters instead of, say, 72?
Regarding roundup, the only place I use that is in my parkinglot at $dayjob and on the road in front of my house (in the cracks around the curbs) or on my driveway. There is no other place where spraying roundup in my yard wouldn't kill either grass or something that my SO would kill me for.
I buy Roundup in premixed 5-liter hand-pump sprayer:

When it's all used up, I clean it with hot water, use some lacquer thinner to wipe away the painted-on label, and use it as a sprayer for Ortho weed-b-gon.
The Roundup I buy in that 5-liter ready-to-use sprayer contains:
Nothing else is listed. No other chemicals, no surfactants.
Could those "preservatives" function as surfactants?
According to this:

================== Glyphosate is practically non-toxic to fish. However, Roundup was more toxic to fish than was glyphosate. An additive used in the Roundup formulation (modified tallow amine used as a surfactant) is apparently more toxic to fish than many common surfactants. For this reason, the formulation for use in aquatic situations (Rodeo) omits this ingredient. The surfactant is used to allow the compound to readily dissolve in solution and to keep the compound from balling up on the leaf surface. ===================
This is wikipedia's page for polyethoxylated tallow amine surfactants:

=============== Roundup Pro is a formulation of glyphosate that contains a phosphate ester neutralized polyethoxylated tallow amine surfactant; as of 1997 there was no published information regarding the chemical differences between the surfactant in Roundup and Roundup Pro.
The polyethoxylated tallow amine used as a surfactant in Roundup is referred to in the literature as MON 0139 or polyoxyethyleneamine (POEA). Presumably, the Roundup surfactant is a derivative of tallow, a complex mixture of fat from the fatty tissue of cattle or sheep.
POEA is 15% of Roundup formulations and the phosphate ester neutralized polyethoxylated tallow amine surfactant is 14.5% of Roundup Pro.
Surfactants are generally required to be used with glyphosate to allow effective uptake of glyphosate, which is hydrophilic, across plant cuticles, which are hydrophobic, and reduces the amount of glyphosate washed off plants by rain. ===============
Does premixed Roundup available in the US contain surfactants?
I spray insecticidal soap on a few locust trees to kill aphids, and might start mixing it with Roundup and Weed-B-Gon as an experiment. This soap contains:
It is the oil on the leaves as well as the sap. Some people are less affected by the oil, but just touching the plant - not squashing it, can cause SERIOUS reactions to a large percentage of the population.
And burning it can be VERY dangerous, as the smoke carries the irritant into the lungs and eyes as well.
Nice theory, except that so far, scientists investigating colony collapse disorder haven't reached any conclusion as to the cause. If they don't kno w, neither do you.
One crop sprayer? Really? Just how dumb do you think we are? Good grief.
Or with perennial weeds that spread from the roots such as morny glory, Can ada thistle etc. I have both in my lawns and garden. Been spraying with bo th 24d and RU since 1976 and it is down to a few thistle and some sprigs of MG in a few spots.
For one thing you piece of shit, I buy it when it's sale ($20).
Second, the retail availability of various lawn-care products have been drastically reduced (and in most cases, banned) here in Ontario, which includes the concentrated version of Roundup. The 5-liter (1.3 gallon) ready-to-use spray is the largest I can buy. Since I don't have acres and acres of real estate to nuke of all plant life, I don't have much of a need for the concentrate anyways.
Yep. A number of years ago I used some of the Weed-B-Gon on my yard to get rid of a dandelion infestation. While it worked well, I noticed that the local squirrels were acting a bit strange for a few weeks afterwards. In the following years, I noticed a similar behavior pattern near other neighbors who used the products.
Now I just go out and pull the weeds every once in awhile. You can pick a lot of weeds in a half an hour (literally hundreds of them), and it's more satisfying to get the chance to kill them up close and personal anyway. Like any "dirty job", I just put on some working clothes and gloves and have at it.
I don't use enough roundup to make it a real concern. I don't have a lot of area (on a sq. footage basis) to nuke of all plant life. Due to political retardation, concentrated roundup is not available at the retail level where I am.
You can buy concentrated roundup that comes in a pump sprayer?
I reformat ALL of the text that I quote so that it remains properly formatted.
AND - for those dumb-ass full-quoters, you shouldn't be dragging the same text through multiple chain-replies anyways. These are not email conversations were having. This is usenet, where the entire thread is ALWAYS AVAILABLE and there is NO NEED TO DRAG OLD TEXT INTO SEVERAL GENERATIONS OF REPLIES.
Missed him on his latest nym shift. Gotta admit he is on topic this time. Canada might get gripped into a weed crisis. We should pass our Mexican weed pickers on to them.
