Fruit IPM for 7/13/17
Peach:
Oriental Fruit Moth (OFM): The 3rd OFM flight is well underway in all counties. These adults produce 3rd brood of larvae, which primarily infest the fruit.
Fruit IPM for 7/7/17
Peach:
Oriental Fruit Moth (OFM): The next and 3rd flight for OFM has begun in southern counties. This will produce the 3rd brood of larvae. First generation eggs are laid primarily on leaf petioles and larvae mine down the petiole into new shoot growth, causing the flagging on terminal growth. The second generation has a similar behavior, but also lays eggs on the fruit, producing fruit infestations. This generation lays eggs primarily on the fruit, and can cause considerable fruit infestation or ‘wormy fruit’ if left uncontrolled or improperly sprayed.

Fruit IPM for 06/27/17
Blueberry:
Spotted Wing Drosophila (SWD): Adult trap captures have remained close to the averages seen the previous week, but maximum trap captures increased in Atlantic County to 30 males per trap on 1 farm. Weekly applications are still required on both Duke and Bluecrop. The same type of program should also include late varieties like Elliott. No infested harvested fruit have been found on any commercial farms as of this date.
