PEST FOCUS
Geneva:
Spotted Tentiform Leafminer 3rd flight started 8/14.
Don't forget this annual event, sponsored by the Departments of Plant Pathology and Entomology, which has been scheduled for September 6-7 this year. All those interested are invited to attend this preliminary presentation of results of field trials on the control of diseases and insects attacking N.Y. fruit crops. Results will be discussed from experiments on tree fruits and grapes. In Highland, the tour of research plots will take place on Wednesday, September 6, from 9:00 AM until noon. In the Hudson Valley, the fall fruit tour is being held only on alternate years. Thus, although there was not a fall tour here last year, we do plan to host it this year. The next day, September 7, the activities shift to Geneva, where presentations on tree fruits are scheduled for the morning, and grape research plots will be highlighted after lunch. Registration begins at 8:30 at the Hudson Valley Laboratory in Highland (Wednesday, September 6) and at Barton Laboratory, NYSAES, Geneva (Thursday, September 7). See you there.
