Codling Moth: In Henderson County and similar elevations, approximately 680 DD have accumulated, which is equivalent to about 50% egg hatch of the first generation. Hence, codling moth remains a potential threat and will be for another 10 days or so. At lower elevations such as Cleveland County, approximately 925 DD have accumulated since biofix, which coincides with about 75% egg hatch of the first generation. Hence, the first generation in nearly complete and there is a low threat of first generation damage at this time.

Tufted Apple Bud Moth:  In Henderson County about 850 TABM degree days have accumulated since biofix, so we are now in the window where a single insecticide application will provide season-long control – provided an insecticide recommended for TABM is used (i.e., Intrepid, Delegate, Altacor, Exirel or Verdepryn).

Aphids, Leafhoppers and Mites:  We are now approaching the time when these indirect pests traditionally begin to become problems on apples. At the research station we detected a few European red mites this week and potato leafhoppers. Green aphids were essentially non-existent, but they are not far off as plenty of winged aphids were present.
