Note: The fungicide listed above are examples. Week numbers are estimates.Spray #3-#8 need to be flexible. Spray schedule will depend on the growth stage and rainfall. You may need to combine two into one spray or need an additional spray (e.g. spray #2.5). Around bloom, Ridomil would be a good choice especially when there are significant rain events. Please limit the use of Ridomil. Alternatives are Revus, Ranman, or Phos acid.
If powdery mildew is the chronic issue for you, it is better to use DMI or other powdery material (mix with sulfur) at prebloom, rather than wait until bloom.
Watch out for 66-d PHI for mancozeb!#6 - whether to include Quintec or Vivando may depend on the level of PM. #7 - You may need to repeat it based on the growth, e.g., #7 was repeated in 2010 and 2011.
We do not have many modes of action for downy. Use mancozeb, captan, and copper as a backbone, and mix and rotate with Revus and Ranman. Do not over use Revus or Ranman (twice/year is ideal). When night time tem gets low (#10 or 11?), you may want to use Revus or Ranman for the last application before fall downy season
If you have an issue with ripe rot, make sure to mix QoI (Abound) or SDHI (Luna or Aprovia) with mancozeb or copper and rotate!
Bird netting maybe needed. Last 3 applications will depends on the level of disease and weather
