Several new pumpkin, squash, and melon varieties that were developed at the NH Agricultural Experiment Station at the University of New Hampshire were released by cooperating seed companies recently. The new varieties exhibit intermediate resistance to powdery mildew disease. Newly released Renegade pumpkin has powdery mildew resistance. The butternut variety Gabrielle an F1 hybrid is similar […]
Long Island Horticultural Research & Extension Center’s Margaret T. McGrath discussed cucurbit disease management in New York at the 2019 Empire State Producers Expo. Managing diseases is an important component of a successful production program for cucurbit crops because there are several diseases that can reduce yield or fruit quality when not adequately managed. The mildews […]
The group determined that bottle gourd rootstocks were effective in imparting resistance to the susceptible watermelon scion and released the two bottle gourd rootstocks that were the most effective in conferring resistance.

Pumpkin management in the final stretch The evidence of proper management shows up now. Some issues can still be addressed, but others required attention months ago. Poor control of Powdery Mildew will result in defoliation, sunburned fruit and weak, brown handles. There is limited effectiveness with rescue sprays for powdery. Fruit rots are triggered in some fields […]
Plant Disease Management Reports published by The American Phytopathological Society are hosted on the Plant Management Network. CucCAP Plant Pathologists contribute to these reports annually.

Powdery Mildew on cucumber and squash in Western North Carolina Powdery Mildew is caused by the fungal pathogens Podosphaera xanthii and Erysiphe cichoracearum. Disease can occur on all cucurbit crops. However, due to the incorporation of resistance genes, most commercial cucumber and melon cultivars are less susceptible. High-humidity (50-90%), moderate temperatures (68 to 80 ℉), dense foliage, and […]
