anyone use this as a soil drench to clear thrip colonization of the root zone?

I just picked some monterey insect spray and was wondering if anyone expects any ill effecs by doing a soil drench @ the rate they recommend for foliar spraying.

many thanks

STB...what I always did was just spray the top of the soil thoroughly...not to drench the entire rootball, just the top inch or two. After 3 applications of foliar to the plant and the top of the soil, your area should be completely void of thrips. The first application gets the majority of them...the follow up sprays are backup.

Its good to hear that your thrip nightmare is over STB!!

Safe enough for me! Does anybody know about Spinosad's ability to continually kill thrips, generation after generation? In other words, have there been any reports of Spinosad-resistant thrips? Because Avid used to be the final solution for spider mites, and after 20 years of every commercial gardener using the stuff, a whole host of Avid-resistant mites have come about....

Great post, Kokua/Sunnyside!

Thanks for the tips Kokua, I apprecaite it!
Ive been doing a similar application method in the past with neem/sesame oil on the top inch or so of medium, but looking forward to seeing the thrips gone for good with the spinosad!

i have some of these thrips, they are as bad as bad trips.
it seems that i can get rid of the issue by using vape mosquito killer,
something like this: liquid mosquito killer iam using it at night, fans turned off.

My friend's in day 20 of flower and he just found 2 thrips in a 10' x 10' garden. Yeh, just 2 - I'm sure he missed a few more here and there. No spotting or anything yet. Should he do anything?

Last grow there were tons of fungus gnats he tolerated, this time he's using mosquito dunks and he sees just one or 2 gnats a day, so they're well under control.

Seeing as thrips larvae live in the soil too and are killed by the bacillus thuriengensis as well as the gnats, is the thrips under control? Will the population explode soon? How about using 10,000 ppm CO2, will that kill them? And does floramite work on them? I'm not sure if it's too late in flower to use it. He has that, but not the spinosad.

Trying out the magic juice kokua. Thanks for the post.

Another control is to use blue sticky cards, with thrip pheromones. They also help show when your problem is beginning.

is spinosad safe to spray during flower? I sprayed once before the flowering was in full force, but they've come back and now i fear that it is too late to spray.

if it's too late for me to spray, should i just try using some ladybugs and nematodes?
