Similar, I have used water and neem oil in a cheapo spray bottle for pests. Neem oil is supposed to be a natural insecticide and fungicide. I was told to treat powdery mildew with it as well. I have used sevin dust in the past, but I think that's extreme cases. I just don't like the idea of the chemicals on my food. OMRI listed neem oil diluted with water, seems alright... stink bugs and tomato hornworms are the big bugs to worry about around here.
