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 FDA Proposed Produce Food Safety Rule Q & A conference call, coordinated by the Produce Safety Alliance, discussed equipment, tools, buildings and sanitation practices that will be affected by the impending Food Safety Modernization Act produce rule.
Here are the questions and answers from that call:
1. Are cats permitted in packing houses? They serve as effective rodent control.
Note white fungal growth and
black sclerotia developing at plant base.

I have seen a number of corn fields with pokeweed emerging along field edges or in patches. These areas should be sprayed before the plants are 10 to 12 inches tall and as result may require some spot applications before the whole fields need to be treated for summer annual weeds. In addition to glyphosate, other effective postemergence treatments include Callisto, NorthStar, Yukon, dicamba (1 pint/A), or Status (5 oz/A). Also note that NorthStar, Yukon and Status all contain dicamba (Banvel) and take precautions so that sensitive plants will not be affected.
