Fruit IPM Report 8-26-2015

Peach

Oriental Fruit Moth (OFM): A fourth flight is now being seen as trap captures start to increase (in apples). Since most peaches are off, this is not a concern in most blocks. However if you have very late varieties, especially if close to apple plantings, then treatments are needed.

Tufted Apple Budmoth (TABM): All treatment timings are over for this pest statewide. The only exceptions would be in northern counties where there may be visible injury, and growers want to continue the use of B.t. products.

Fruit IPM Report 8-18-2015

Peach

Oriental Fruit Moth (OFM): The third flight and all required treatment timings are now over throughout the state. Additional treatments will only be required on very late varieties, and only if trap counts exceed 6 moths per trap. We are seeing some high trap captures in some orchards.

Tufted Apple Budmoth (TABM): We are in the middle of the second flight, but pest pressure is very low. On most farms treatments are not needed. If you did have feeding injury from the first generation or have high trap counts, then you may wish to observe the following TABM timings.
