Apple Pest Report July 30, 2003

Apple Pest Report: Wednesday, July 30 , 2003
Vol. 11 No. 11

A few quick notes: 1. Apple maggot trap catches at Highmoor Farm are very high this year. This does not appear to be a year to take chances with letting apple maggot coverage lapse. Unless you have trap data indicating otherwise, continuous protection should be maintained until a final insecticide application is made no earlier than August 15 (and preferably a bit later if preharvest interval allows it.) 2. Second generation leafminer mines are now appearing, but population at Highmoor is very low. Brian will be checking for LM at IPM Scouting Co-op blocks next week. Because first generation populations were very few around Maine, I do not expect second generation problems, but still worth a look.			3. European red mites continue to be remarkably low. 4. Second generation codling moth egg hatch expected to begin around August 9 at Highmoor Farm in Monmouth. See Orchard Radar for other sites. 5. Time to consider status of your fungicide coverage against flyspeck. Full dose captan applied before July 11 has probably lost efficacy at preventing flyspeck. See New England Apple Pest Management Guide for flyspeck fungicide interval guidelines. Captan at full dose is good for 21 days or 2.5 inches of rain between applications. See Orchard Radar tables for updated estimates based on recent and forecast weather.

Sincerely,
Glen
