Cucurbit downy mildew confirmed on pumpkin in Morris County – 8/6/13
Cucurbit downy mildew has been reported on pumpkin in Morris County. This is the first report of downy mildew on pumpkin this growing season. Cucurbit downy mildew has also been showing up on cucurbit crops (other than cucumber) in other states this past week. All cucurbit crops in New Jersey are at risk for downy mildew. Downy mildew specific fungicides should now be a part of all weekly fungicide maintenance programs if not already initiated. For current 2013 Cucurbit Downy and Powdery Mildew Management Guidelines please see post from 6/7/13. If you suspect downy mildew on any cucurbit crop please contact your county agent. Please visit http://cdm.ipmpipe.org/ to track the progress of downy mildew throughout the US.

Vegetable Disease Briefs – 8/2/13
Although conditions have been favorable, No Late blight has been reported in New Jersey this past week.
Basil
Downy mildew remains active – All basil growers should scout on a daily basis and should add a labeled downy mildew specific fungicide to their weekly fungicide program. Phosphite fungicides (FRAC code 33), such as Prophyt, K-Phite, and Rampart have shown the best efficacy in trials at RAREC. Actinovate (OMRI- approved) is also labeled for downy mildew control. Please remember, all abandoned basil fields should be worked under immediately after last harvest to kill the foliage! Abandoned fields left unattended after use will only serve as a source of inoculum for other fields. [Read more…]
