chalyse,
Below 86-90 degrees for rust dormancy? I thought it was above 92 degrees! Usually by this time of year the temp. is high enough what ever the requirement that I don't have much rust, then it shows up again when the weather starts cooling off. So here the normal pattern should be rust early and late but limited rust during the really hot weather. I think I sprayed some early, but nothing like what I did last year, did the spraying prevent the rust from returning this year, could have, but we did have the very cold winter this past year(for here) and that could also be a reason for no rust.
