Cucurbit downy mildew has been confirmed on pumpkin and butternut squash in New Jersey. Cucurbit downy mildew was confirmed on summer squash in southern New Jersey a few weeks ago and cucumber earlier this season. Remember, some CDM isolates fall into Clade I which predominately infect watermelon, pumpkin, and squash, where other CDM isolates in Clade II predominately infect cucumber and cantaloupe. All cucurbit growers should scout on a regular basis and initiate a weekly CDM fungicide program.

Aspergillus mold species often show up after drought conditions, posing a significant risk of aflatoxins in the corn crop if present. Aspergillus molds are carcinogenic to people and cause losses in livestock and poultry. Combine operators and elevator operators should take precautions against inhaling fungal spores. Signs of Aspergillus ear rot include evidence of powdery olive-green mold on the ear tip or on kernels in the ear.
