Alan,
I forgot to mention that Strobilurin
(Sovran, Flint) and sterol inhibitor (Nova, Procure, Rubigan) fungicides are
absorbed into the leaf and fruit tissue after application (once the residue has
dried) and are not affected by rain wash-off. The protectant (Dithane, Manzate,
Penncozeb, Captan, Ziram, Thiram, Polyram) fungicide residues can be affected by
rain. I usually mix Nova with Dithane or Captan and Flint with Captan or
Dithane so I have rain pretty much covered.
