In her talk, “Resistance to fungicides in vegetable pathogens: current situation and strategies for managing”, McGrath emphasized the importance of resistance management – specifically through monitoring and delaying development of resistance by rotating chemistries. Multi-fungicide resistance remains a constant concern, exemplified by cucurbit powdery mildew isolates present on Long Island that are resistant to 6 […]

September 5 Vegetable Updates | MSU
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 […]
August 31 Vegetable Production Update | NC State
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 […]
August 22 Vegetable Updates | MSU
Vegetable crops and their response to nitrogen Most cucurbit crops do not convert nitrogen to fruit very well. Their response to excess levels of nitrogen is to grow more plant, which potentially leads to increased disease problems and later production. Increased diseases can occur because the increased leaf canopy inhibits air movement leading to increased […]
