Downy mildew was confirmed on cucumber in Mifflin County on July 11. Warmer weather throughout the state is helping crops along, but has also been good for insect pests.
Cloudy weather, rainstorms, and variable temperatures across the state have slowed some crops and created very favorable conditions for disease development.
Conditions are optimal for fire blight, apple scab, and rust infections. Growers are encouraged to keep trees protected. Other diseases for the fruit grower radar are also discussed.
Bloom is well underway in parts of PA and MD. Fire blight and scab disease conditions are in full force now. Growers are encouraged to protect trees.
Consider applying dormant sprays soon to manage fungal and bacterial diseases this season.
