I have found that Neem works well for mites and PM. But real Neem for mites, not the refined 70% Neem that has all of the azadirachtin
removed. It is a contact spray, so you have to saturate the entire plant to be effective. Mites have tiny webbing that they cover the eggs with, and while Neem will kill eggs on contact, it may not get through the webbing. Adding soap helps, but some of the Neem oils that I have say not to use a spreader (soap) with it. So you need to spray at consecutive intervals to kill all the stages of mites once they hatch. Spider, cyclamen and broad mites mites all hatch into larvae in 2-3 days time. So spray every 3 days to kill any emerging eggs. Usually 3 spray cycles will be enough. I typically spray Neem as a preventative for PM and mites every 2 weeks.
As for Neem/oil/soap and resistance, mites cannot become resistant to the oil and soap sprays. This is because oil coats and suffocates them, and soap lowers water surface tension, and drowns them. They cannot evolve to become resistant to these actions.
Also with Avid (abamectin) and Neem (azadirachtin
), they both break down under ultraviolet light, so if you grow outdoors, you should be fine with using either one. Abamectin is trans laminar, meaning it will penetrate the leaf and kill the mites dining on it on the other side. This allows for less than 100% saturation spraying (which is hard to do effectively). Abemectin is also 100% effective for mites that it comes in contact with (direct or trans laminar). Abemectin will not kill eggs though. Soaps and oil sprays are more like 80% effective in studies done at WSU and OSU, but they will kill all stages of mites and their eggs on contact. So in both cases, multiple applications are required for complete eradication.
