pesticide chart

bspoffordDecember 20, 2007

A couple of months ago I was noodlin' around on the 'net and came across a 'pesticide' chart/table for av's. It had the various pests and pesticides listed and indicated which pesticides could be used for each critter.

I can't find it and don't remember where I saw it. I should have printed it at the time.

The program for the next club meeting is on pests, and this laid it out pretty simply. It looked something like this with lines to form boxes:

pesticide------------- Malathion Kelthane Marathon etc.

pest

thrips

soil mealies

foliar mealies

c. mites, etc.

An 'x' was used to indicate which was effective for that bug.

Do any of you have the faintest idea what I'm talking about?

Hi Barbara
I went poking around and found this site. It may not be exactly the one you were asking about but it does have a chart like you describe. Good luck with your new club.

Hi Barbara -

I would think we need to have an additional row in the table -
median lethal dose, LD50 - the amount of substance per 1 kg to kill 50% of tested population (usually rats)

Malathion -1375 mg/kg LD50 rats
Kelthane. LD50 for rats  575 mg/kg
Marathon - 460 mg/kg
Pyrethrine 2000-4000mg/kg

It means that you need to consume half of a pound of pyrethrine to have 50% chance to keel over, or an ounce of Marathon provided you have a weight of 130 pounds (I guess some lucky girls ARE of this weight).

SO - when you choose the treatment - check this number - and use the biggest number possible. You do not need to expose yourself to something deadly - to run off the thrips. Lice shampoo (pyrethrine) works - and I cannot imagine anybody accidentally consuming a bucket of shampoo. (0.5 pounds of active ingredient - and shampoo has 4% of it - 12.5 pounds of shampoo.

Let's drink champaine, not shampoo.

Cheers

vtstar, that's it! I even had looked at that very thing yesterday, I just didn't scroll down to the bottom.

Irina, the scientist in you puts frosting on the cake.

Thanks to you both for your help.
