Neem for leafminers


I have leafminers on my boxwood hedge. Someone gave me Neem concentrate to spray on the boxwood. Does anyone know if Neem will effectively kill the leafminers?

they are in, not on the leaf. I dont think so. how about a systemic? I used it to get rid of leaf miners on a birch. worked great. Ingrid

Neem may work, however check this out: "http://news.bbc.co.uk/2/hi/south_asia/3977351.stm "
*grin* It's possible that the high sugar content attracts ants on to leaves when it's sprayed..

What kind of systemic product did you use? Someone mentioned using malathion, but we have dogs and an outdoor cat, so I was concerned about the stuff getting in their eyes. Isn't Malathion highly poisonous? Right now the leaves are blistering, and I suppose the eggs are beginning to hatch. I am in zone 7, Virginia. I have done a little research on boxwood leafminers, and know what they are and how they work, but just don't have any experience with using systemics.

Malathion's great stuff: http://www.scorecard.org/chemical-profiles/summary.tcl?edf_substance_id 1-75-5

Thanks for all the suggestions. I finally got some "Merit" by Bayer. Hopefully that will solve my boxwood leafminer troubles.

Another great chemical. Be careful: http://www.scorecard.org/chemical-profiles/summary.tcl?edf_substance_id 89%2d84%2d5

It has been so long since I used it I dont remember which systemic. big tall round cylinder of a can. malathion is poisonous to everything without a functioning liver. otherwise, it is pretty useful when used correctly to treat existing infestation. it biodegrades pretty fast too. Ingrid

http://en.wikipedia.org/wiki/Malathion
I'll quote: "However, malathion breaks down into malaoxon, which is 60 times more toxic than malathion."
"Malathion present in untreated water is converted to malaoxon during the chlorination phase of water treatment"
Also:
"Malathion was used in the 1980s in California to combat the Mediterranean Fruit Fly."
"Malathion was sprayed in many cities to combat West Nile virus."

and we all know how reliable wikipedia is. where is the scientific articles showing this? Ingrid

The first half of the statement is true. If there are high schools where you live, and you hurry before they close for summer, you can ask a chemistry teacher and she/he will explain the chemical conversion to you. Since you're a very smart person, I assume you will then accept the statement as true.
The second half is probably the one that bothers you, right? If you were to see three sources of this information which you consider to be absolutely reliable, who would those sources be? Perhaps I can help you find the information. It would be this type of thing:

I think you'll find that interesting, in a way that's sadly predictable. Come on back real soon and we'll talk about it.

Gee, Ingrid, I know it's inconvenient to have to actually THINK about the chemicals you use, but that's reality.

Hello Ingrid, The Wiki - in most cases, quotes sources; If you scroll down to the bottom of that page you'll find them. I won't debate Wiki reliability since that may be construed as being off-topic.
My post was meant to show both sides of the coin, and get the original poster to check the Wiki ( in case he hadn't ); After all I did post specific instances where it was used ( from the Wiki ). My post wasn't meant to lessen the value of your own personal experience with Malathion, however the poster must be warned about the risks involved in handling chemicals.
In this particular case: 1. Enclosed areas with poor ventilation - like a gardening shed. 2. Reaction between Malathion and Chlorine ( tap water is chlorinated ). 3. Impurities that may cause harm. 4. Malathion getting in-to drinking water.
