Peach
Oriental Fruit Moth (OFM): While overall pest pressure in peaches is very low for oriental fruit moth, we are at the proper time to treat if your farm has trap captures above 6 males per trap. Timing for third brood OFM applications are as follows:
| OFM 3nd Generation Timing | ||||
| Insecticide Type | ||||
| County/Region | Degree Days by 7/22 base 45 |
Conventional | Intrepid/IGRs | Diamides |
| Gloucester-Southern | 2317 | 1st – 7/17-19, 2nd – 7/27-28 |
1st – 7/14-15, 2nd – 7/25-27 |
1st – 7/13-18, 2nd – 7/24-27 |
| Hunterdon-Northern | 2053 | 1st – 7/24-28, 2nd – about 8/5-7 |
1st – 7/22-24, 2nd – about 8/3-5 |
1st – 7/22-23, 2nd – about 8/3-5 |

Brown Rot Management in a Wet Growing Season: Part I
Mid-July has arrived and the 2015 peach harvest season has begun in earnest.

Since spores of this pathogen require water to germinate, the number of fruit infection periods and therefore severity of the 2015 epidemic will be very much dependent on the number of rainfalls.
