Hello Doug, I think it is commonly accepted that when you spray sulphur on a routine basis, mites will not quickly pose a problem, because as well as suppressing the predatory mites, the sulphur also suppresses the pest mite species. However, it is when you stop using the sulphur (perhaps next season?) that the pest mite species can multiply quickly in the absence of the predatory mites.

Trying to keep costs down since we lost our crop, and having too much mildew show up. Sulfur is cheaper than the other mildew fungicides, but how quickly will we get into mite problems, if sulfur kills my beneficials? Doug Doug and Leslie Balsillie 793 County Road 50 East, R.
