So I spoke with a friend about my root aphids and he suggested Botanigard WP. I have now experience with is product and have not seen it referenced on this site.
***I also found this, but I am not sure, it is quite involved and seems like a lot of chemicals. Could you folks with greater experience help?
Had to have been
Really read that I did and I’m telling you this article will help you
They can stay around for many grow cycles indoors
I hadn’t been aware of the problem they really are
Yes I read that too and idk …
I think you will have to sterilize everything after this grow anyway so that may be a last resort
I read in that other article ypu can use spinosad as a soil drench
I really like @oldmarine idea of the nematodes
He’s having success with them and they may help you
I say this because any method of soil drench you use will most likely not get under the root ball but living organisms trying to eat will
I had a bad root aphid issue, to the extent I cleared a 8x4 with the exception of 1 clone. That 1 clone I did a dr zymes root drench, every other day for 5 applications. Also did foliar spray before lights out. She made it and is currently in her 48 hour dark period, Ill post pics later.
Point being its feasible to contain or get rid of them, but there was no way I could do soil drenches on that many plants.
Now, I use beneficial nematodes as a preventative. And they look to do the job, I am running full organics indoor during heat of the summer, and I have a rare fungus gnat or two. I would expect to see a lot given the funk of my medium.
I have been going through this problem as well Ive had so much rain where I am and out of nowhere these suckers just popped up. I could not find the original post to give them credit for this spray that i have used and i absolutely love it now. It is 1 cup of veg oil mixed with 1 tablespoon of Dr. Bronners soap ( they sell it at target in the beauty section). Cover that shake it and then add 2 teaspoons to a quart of water and spray on the affected areas.
I lost one of my ladies to them and I notice my other 2 had some i made this spray and watched them come right off and i will be washing them tomorrow and then re spraying it was good to know i could save them unlike the other one but they are so close to harvest i cant lose another.
Good luck with your problem its not always easy getting rid of bugs ive learned the hard way
Lucky you! it might work in the soil im not sure though some people have told me chili powder or cayenne pepper… I had that on the top of my soil because it kept the cats away from my outdoor and once I stopped boom issues with nasty bugs. good luck to you!!
