Good fungicide coverage is important for disease control. Check fields for the presence of powdery mildew. Do not make any more than two successive applications of Quadris to prevent resistance development in the powdery mildew population. Nova or Quadris will provide excellent powdery mildew control and Quadris will also provide black rot control. Bravo is still very good for downy mildew, and black rot, again good coverage is very important.
Fungicides are important for good fruit quality including good handles.
This will be the last late blight FAX for the 1998 season. Most potatoes are done and conditions for late blight certainly have passed for this season. The weather monitors will continue to collect data, but I will not be faxing anymore reports this season. If anyone has very late potatoes and wants the information, please give me a call. I hope digging and marketing season is successful for you.
