My experience, just had an entire flower room get infested with thrips. I noticed the silvery specs on leaves and ID'd the thrips with my microscope early on in the infestation. Sprayed with neem, pyrethrum, used DE on the soil, all that stuff did was maybe slow them down some. Basically didn't do jack shit to get rid of them.
Anyway im mid way through flower and i walk into my room 2 days ago much to my horror a couple of my girls have just been completely raped by these thrips. Im talking within 24 hours it went from leaf damage to full on leaf death. At this point i sprayed entire room down with spinosad, and im very glad i did it. I reckon if i had of left this any longer i would have lost entire room. Luckily the main damage is only a couple but the entire crop is undersize by like 20-30% i would guesstimate. The root damage caused by larvae has also pre yellowed a number of my plants just like what fungas gnats do. If your familiar with nitrogen levels in your soil and your getting early pre yellowing around day 35 then check your soil your going to see hundreds of these vile critters in there DO NOT let these thrips get hold of your room. Its like they build up slowly over a period of time and then POW, they just takeover. I'll post results of spinosad trreatment as they come to light but i know its working already seen dead thrips

Yup ^^^ basically exactly like that Noyd. What happens (if you don't already know) is the damaged leaves stay like that for a while and then eventually the entire leaf will just collapse and die and turn into a big brown mess as the thrips takeover. It happens REAL FAST when it gets to this point. The infestation sneaks up on you real sneakily and the worst thing is if you don't find the spinosad in time and keep spraying neem etc.. it can (and will) cripple your entire operation.

SPINOSAD FTW YO!!!
After a quite nasty thrip infestation in mid flower, i sprayed entire room down twice, 5 days apart, with a spinosad soil drench as well just to get the top couple of inches of medium where all the larvae are. Ive just inspected everything and i couldnt be happier with the spino. It for sure works on the larvae too i saw a couple of survivors limping around the edge of the grow bags and they were moving SLOW, like they would be dead very soon. They were over. Didn't see one in the soil which is incredible given i had thousands of these things. This has been said before but i'll say it again if you have thrips, DO NOT mess around with any pest controls other than spinosad, you'll only waste your time and give the thrips time to multiply. That is all. Just do it!

WHAT AM I DEALING WITH ? ? PLEASE HELP!
Hi guyz! Lovely thread...but i really can't understand what i am dealing with here....
I noticed some yellowing on leaves but thought it would be from low nutrient . 5 NL5xHaze feminized for 20 days under 24 hour light. After i raised nutrient level and added some diamond nectar the yellowing was corrected, however I noticed a little visitor...I killed it yesterday and today i saw another one which i killed again with the edge of the knife. I give u pics from the microscope through mobile lol...but that's what i have...please help me identify what they are and check for either GNATROL or SPINOSAD depending what they are...PLZ HELP!!! Killed yesterday: |
