We are a commercial Marijuana farm in Central Oregon and are having problems with Aphids. Their are certain things we cannot use because the state mandates what we can and can't use; Pyrythian is one we can't use. We have tried Soap and water. Essential Oils. None of them have worked. We have tried Azazol, and nothing seems to work. Can you possibly give me some idea on how to get rid of them?

I would recommend contacting the Oregon Department of Agriculture as they may be able to offer assistance. http://www.oregon.gov/ODA/agriculture/Pages/Cannabis.aspx
