Subject: Powdery mildew of pepper discovered in New York

Powdery mildew of pepper, caused by the pathogen Leveillula taurica, was observed for the first time on pepper in western NY in August 1999 and on Long Island, NY in 2000, both in commercial fields planted with transplants from Georgia and Florida. Symptoms were observed on all cultivars of bell and chili pepper in the Long Island field, but not on tomato or eggplant in adjacent rows. Powdery mildew of pepper was first reported in North America in 1971, when it was observed in southwestern Florida. Presently, powdery mildew is considered a recurring problem on tomatoes and/or peppers in California, Utah, Nevada, and Arizona. This disease is expected to be different from that in the western US because environmental conditions are different than those in the northeast.
