Greetings, After some discussion, we have elected to forego having reminders of Entomology updates for degree-day accumulations, management recommendations, and pheromone trap data sent automatically via e-mail notification to those on our e-mail recipient list. We chose this option since we felt that three e-mail notifications per week through most of the growing season may be overkill. Consequently, we ask that users of this information simply bookmark the locations of relevance to them and visit them at your convenience. As we have done in previous years, we are updating degree-days, predicted egg-hatch and management recommendations for OFM, CM and TABM twice weekly, on Monday and Thursday. Data for OFM and CM are provided for Winchester, Timberville, Nelson county, Rappahannock county, and Patrick/Carroll counties. Data for TABM are provided for Winchester. Pheromone trap data from the Winchester research station are updated on Wednesdays.
On April 29, the Environmental Protection Agency approved a Section 18 Emergency Exemption authorizing use of dinotefuran against brown marmorated stink bug in pome and stone fruit in VA, WV, MD and DE (some other eastern States to follow) in the 2014 growing season. Venom Insecticide can be used at rates of 4.0 – 6.75 oz/acre and Scorpion 35SL Insecticide at 8.0 – 12.0 fl oz/acre. A maximum of two applications per season is permitted (not to exceed 0.608 lb/a.i./acre/season). These products have a 12-hour REI and a 3-day PHI in pome and stone fruit crops. Dinotefuran is highly toxic to bees and cannot be used until after petal-fall. Given its efficacy against brown marmorated stink bug and its short PHI, we recommend its use later in the growing season, in the weeks and days preceding harvest. This Section 18 expires on October 15, 2014.
