I'm growing tomatoes hydroponically in a small home greenhouse. I have an infestation of russet mites. Recently I've used Fertilome's Triple Action Plus (Neem Oil) with they claim will control mites. My experience thus far is that it is not very effective in dealing with russet mites. It may kill a few of them, but a day or two after spraying they are many, and very active.
If anyone has a potion that will eliminate my russet mites, I hope that you will share it with me. I would prefer not to share my tomato plants with the mites.
