In part I of this article series, we discussed the sources of inoculum for fruit infection by the brown rot pathogen, Monilinia fructicola (see July 21, 2015 article).
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 |
Mid-July has arrived and the 2015 peach harvest season has begun in earnest. As each successive crop of fruit mature and ripen, they become susceptible to infection by the brown rot fungal pathogen, Monilinia fructicola. 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.
Oriental Fruit Moth (OFM): The third brood should be treated based on the timings below. Overall pest pressure is light with some exceptions in northern counties.

Oriental Fruit Moth (OFM): While we are still between flights, trap counts indicate a slight pick up of moth activity for the start of the 3rd flight. The first insecticides will be due by the middle of the month in southern counties and about a week later in northern counties. Time your sprays according to the following table:

Oriental Fruit Moth (OFM): We are between 2nd and 3rd generation broods in southern counties, but still treating emerging larvae in northern counties. Growers who have trap counts that are less than 6 moths per trap can skip insecticides that are intended for OFM. If trap counts are higher, then time your sprays according to the following table:
