Where black rot is a problem, apply a fungicide every 14 days after the "New Shoot" spray up to and including the "Before Ripening" spray. During long rainy periods, shorten the interval to 7 to 10 days between sprays. Spray in the rain, if necessary, to maintain the schedule of applications. Always consult the label before making pesticide applications. Labels vary greatly among commercial products of the same material. It is important to refer to the label for the best timing and application rates when applying pesticides. Also read the text for information on cultural practices to minimize the application of pesticides. Due to a wide array of various products containing the same active ingredient, for insecticide recommendations, when appropriate, the active ingredient is listed instead of the name of formulated product.
Follow all instructions and application rates listed on pesticide labels.
Captan + Mycobutanil or Mancozeb + Mycobutanil for diseases.
Carbaryl (rose chafer) or Imidcloprid (leafhopper)
Mancozeb + Mycobutanil for diseases.
Bacillus thuringiensis (berry moth), or Imidaclprid (leafhopper)
