I've been growing for 8 years full time. I know what I'm doing. I just posted these pics because in all my experience growing and the dozens of other grows I've seen I have never seen anything like this before. I was wondering if anyone else has seen this before. I still appreciate the words of encouragement though
Their not root aphids - Be very glad!
Looks like your getting a BAD Whitefly attack to me!
Whiteflies are a pain in the ASS! If your crops are in now and you have nothing going - SANITIZE very heavily !!!
Use a bleach mix and you might do well by mixing it heavy a bit.
Now spray down EVERYTHING in the grow. EVERY surface! Include undersides of anything, insides of anything that they COULD have gotten into and all fans, cooling equipment, etc, etc. Leave NOTHING out! Put out a BUNCH of yellow sticky traps all around and look for those White flying critters. If you see some - clean again....If you see some ON your plants - go to the next step bellow.
Whiteflies are tough bastards as they become resistant FAST! You need to get out all the big gun poisons for these suckers and use them in
rotation for several weeks - 5 weeks in 5-7 day increments ! Start with - Pyrethrin - Permethrin - Clothainidin - Imidacloprid and then hit with Insecticidal soap.. The bottoms of the leaves are the PRIMARY goal for some (contact killers) and the other 2 are systemic so cover as the label instructs for Whiteflies
If it gets out of hand or you don't/won't use the real insecticides listed above.....You have NO choice but to ditch and start over after CLEANING.....
Don't anyone come on here and say that you killed them off with Neem oil as I KNOW that's bull shit!!! Of the first order!
You can NOT kill off an infestation like pictured with natural means by any method.....You might slow them down some but, not for long!
Sorry about your white flies! I can deal with root aphids ok. It's white flies I dread the most!
