Veg IPM Update: Week Ending 10/05/16
Sweet Corn
Corn earworm moth (CEW) activity has been fairly steady over the past week. Patches of locally higher activity remain within a generally low population (see CEW map). Catches are now rising and falling with night time temperatures. It is advisable to incorporate materials into the spray program that have different modes of action from the pyrethroids. This includes IRAC 28 materials like Coragen, Exirel and Besiege, as well as IRAC 5 (Radiant, Entrust (OMRI approved), and Blackhawk)). Growers should be checking CEW activity frequently, and adjust spray schedules according to local activity. On this map, green areas correspond to a 3-4 day silk spray schedule, while blue is 4-5 days.
The highest nightly CEW catches for the previous week are as follows:
| Centerton 3 | Denville 1 | Milford 1 |
| Green Creek 2 | Eldora 1 | New Egypt 1 |
| Blairstown 1 | Farmingdale 1 | Sergeantsville 1 |
| Califon 1 | Jones Island 1 | Tabernacle 1 |

Sweet Corn
European corn borer (ECB) moths are nearly non-existent now. There are no particular areas of higher activity, and no map will appear in this edition. It is unlikely that we will realize any further injury from this pest this season.
Nearly all remaining sweet corn plantings are now in the silk stage. Fall armyworm (FAW) however, continues to be a threat to these sweet corn plantings. We should expect this pest to be with us at some level for the remainder of the sweet corn growing season. FAW do not respond well to pyrethroid insecticides. The most useful products are those in the IRAC group 28 class (Coragen, Exirel) or the IRAC group 5 class (Radiant, Entrust), or combination products including these classes. See the 2016 Commercial Vegetable Recommendations Guide for insecticides effective against FAW.

Sweet Corn
European corn borer (ECB) moth numbers have decreased this past week such that only a handful of moths were captured. There are no particular areas of higher activity, and no map will appear in this edition. It is unlikely that we will realize any further injury from this pest this season.
The highest nightly ECB catches for the previous week are as follows:
| Cinnaminson 1 | Milltown 1 |
| Clinton 1 | Pedricktown 1 |
| Hillsborough 1 | Sergeantsville 1 |
