A program for SCAB CONTROL

摘要

Growers producing apples in the cool, damp northeast quadrant of the United States need to take a step-by-careful-step approach to apple scab control— starting early and being meticulous—or they can be in for a long summer of expensive spraying andstill lose part of their crop to this fruit-disfiguring disease. Dr. Kerik Cox, a Cornell University plant pathologist who advises growers in western New York, said that he and other plant pathologists in his state—and across the Great Lakes, Midwest, and Mid-Atlantic region—are in close agreement on the advice they give growers and in explaining the reasons for it.
