5-14-13 Potato Report Updated report. Sorry folks, the information at the bottom of the original 5/14/13 report was not intended. No reports of Late blight in NJ.
Welcome to the new potato report for 2013! As always, we will be tracking DSVs for Late blight development and calculating P-days for initiating the first early blight fungicide application. Remember the threshold for P-days is 300! Once 300 P-days is reached for your location early blight fungicide applications should be initiated.
With the wet weather we’ve experienced in New Jersey over the weekend and the warm temperatures to follow this coming week Phytophthora blight (P. capsici) and Pythium are likely to start showing up in pepper, tomato, and cucurbit fields. [Read more…]

The strobilurin, or QoI fungicides (FRAC code 11) are extremely useful in controlling a broad spectrum of common vegetable pathogens. You may know some of strobilurins as azoxystrobin (Quadris), trifloxystrobin (Flint), pyraclostrobin (Cabrio), or Pristine (pyraclostrobin + boscalid, 11 + 7). [Read more…]
