Don't forget this annual event, sponsored by the Departments of Plant Pathology and Entomology, which has been scheduled for September 910 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.
IMPORTANT - Please note the switch in the order of venues. First this year in Geneva, the tour of research plots will take place on Wednesday, September 9, from 8:30 AM until noon. On Thursday, September 10, the activities shift to the Hudson Valley, where there will be presentations on disease and arthropod control in tree fruits. Registration begins at 8:30 am at Barton Laboratory, NYSAES, Geneva (Wednesday, September 9) and at the Hudson Valley Laboratory in Highland (Thursday, September 10). See you there.
