Sorry if this is a duplication: I tried attaching Art Burrell’s discussion of sulfur sprays with the following message, but I think that made the message size too large for this list-serve.
I can only reprint what Dr. Art Burrell said in 1945 at the 90th Annual Meeting of the New York State Horticultural Society: “Let us assume that, when the weather has cleared and the trees have blown dry, we find on Mills’ chart that they have been wet long enough to have permitted scab infection, and we still have trees that were not protected [by sulfur sprays discussed earlier]. This is where lime sulfur 2-100 comes in. We must wait until the leaves have become dry, because in a soaked condition, they are especially subject to burning.” ******************************************** Dave Rosenberger, Plant Pathologist, Hudson Valley Lab, P.O.

It is listed as having 72-96 hours back-action in the New England Tree Fruits Management Guide. In my particular situation, Half-Inch Green stage tissues were exposed many hours during two of the previous three nights to 18-20 degrees F, and are probably extra sensitive to captan penetration and phytotoxicity.
