Branching Out is a newsletter prepared by faculty and staff in Cornell’s Department of Plant Pathology. From mid-April through mid-July we publish one issue every two weeks and from July through September, we publish every three weeks for a total of 11 issues per season. Information published in Branching Out informs pest managers throughout New York state and surrounding states of the progress of insect and disease pests in trees and shrubs in their areas. We also report growing degree days and phenological observations.
