Sweet Corn Cool night temperatures and a declining late European corn borer (ECB) generation have resulted in very few moth captures this past week (see ECB map). Damage from this pest is largely being overshadowed by that of the fall armyworm. Very few plantings remain that are not silking. However, consider treating when the number […]
Continue reading...Extended periods of long, hot dry weather can cause pumpkin fruit to seemingly mature quicker (i.e., turn orange). Sunscald injury occurs when cucurbit fruit are suddenly exposed to direct sunlight during the latter stages of fruit ripening during the fall. Sunscald injury often occurs after plants prematurely defoliate due to powdery mildew or downy mildew infection or when vines collapse […]
Continue reading...Downy mildew remains active on all cucurbit crops. All cucurbit growers should include downy as well as powdery mildew specific fungicides in their weekly maintenance sprays. Please remember different modes-of-Action (i.e., FRAC groups) to help manage fungicide resistance develop in both pathogens. To track the progress of CDM in the US please visit http://cdm.ipmpipe.org/ There […]

Sweet Corn Only a scattering of European corn borer (ECB) moths are being captured now, with somewhat more consistent catches in Mercer County (see ECB map). Damage from this pest is largely being overshadowed by that of the fall armyworm. As always, consider treating when the number of infested plants in a 50 plant sample […]

Phytophthora blight (P. capsici) and bacterial leaf spot (BLS) are the two greatest pathogen threats to pepper production in New Jersey. Articles in the Plant & Pest Advisory, such as Phytophthora Control During Wet Weather, Controlling Phytophthora Blight in Pepper, and Bacterial Leaf Spot Update, have talked about why growers are experiencing increasing crop losses […]

Today’s rain got me thinking about insect damage in turfgrass. Actually I’ve been thinking about insect damage in turf for a week or so, ever since I saw a flock of birds pecking sod webworms out of the bentgrass plots behind the Plant Diagnostic Laboratory.
