Hey just wanted to share with farmers what worked for me. I caught the mites early... only saw a few single webs between fan leaves, one of the plusses of going downstairs and just staring at the ladies, ha! :pimp:
After reading this thread I put together a game plan:
1 gallon mix:
20ml
azamax (for its systemic properties and is essentially concentrated neem)
30ml mildew cure (clove, garlic, etc. to prevent mildew/etc. in high humidity conditions after spraying during dark hours.
10ml rosemary extract from WholeFoods. Apparently SNS217 (which rocks!) is essentially rosemary with some systemic additives. And seeing as how its ridiculously expensive, its worth making at home in my opinion. After application it looks similar to neem, leaving a shiny polish on the leaves.
6ml dish soap as an emulsifier for the oils like rose mary.
So we have a non-systemic leaf coating to choke out eggs, a systemic additive to deter adults from feeding and some other herbs to F&$% with the mites life even more as well as deter any fungus that may enjoy the high humidity that the mites hate.
1 gallon made 4 heavy applications. Applied right after lights off. No signs of mites after 1 application, and did 3 more weekly just to be safe. Spent a bunch of time with a 20x hand scope lookin' for those little bastards! I found throwing trash bags over my canopy helped limit over spray when spraying upwards and kept the lights clean.
Caught early, this seems like a very effective, pretty darn close to organic solution for mites. However, I've just been using it myself so it may not work for different species of mites in other locations or more advanced infestations.
Peace!
