Basically, I do Surround/sulphur/spinosad/Bt/Regalia (all in one tank) from petal fall through nickel sized fruits. I then spray on an as-needed basis, e.g. now I am in 2nd generation OFM so am back to Surround/spinosad/Bt spraying. Then in mid-summer am adding Indar for brown rot, and I also spray some Indar earlier to nip it back.
