Rutgers Cooperative Extension
The Plant & Pest Advisory serves NJ growers by reporting on important pests and recommending responses that are grounded in reproducible trials.
Articles in this section contain information helpful to the NJ commercial organic grower.
Sharing organic practice trial results between land-grant universities is a cost effective way to create a common knowledge base built on the strengths of individual programs. In the sidebar, find institutions with programs in organic agriculture which augment knowledge developed at the Rutgers New Jersey Ag Experiment Station.
Rutgers Cooperative Extension Field Guides: These concise guides help with decision making from pre-planting to harvest. For each crop listed, learn what pests to proactively look for as the season progresses, how to look for them, and when to take action.
Sweet Corn
European corn borer (ECB) moths have been captured at a few more locations over the past week, although recording sites are relatively few and numbers are very low. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 08/04/21 are as follows:
| Blairstown 1 | Hillsborough 1 | New Egypt 1 |
| Downer 1 | Medford 1 | |
| Flanders 1 | Milltown 1 |
Sweet Corn
European corn borer (ECB) moth catches continue to be extremely low around the state. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 07/28/21 are as follows:
| Crosswicks 1 |
| Matawan 1 |
Sweet Corn
European corn borer (ECB) moth catches continue to be extremely low around the state. We are in between adult generations at this time. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 07/21/21 are as follows:
| Centerton 1 |
| Milford 1 |
Sweet Corn
European corn borer (ECB) moth catches continue to be extremely low around the state. We are in between adult generations at this time. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 07/14/21 are as follows:

NOTE: Cucurbit downy mildew (CDM) was detected on cucumbers at the Snyder Research and Extension Farm in Hunterdon County on Wednesday 07/07/21. No other cucurbit crops exhibited signs of infection. Growers should assume that CDM races that infect cucumber and possibly muskmelons are now active in ALL parts of the state. See the Pumpkin and Winter Squash section below for more information.
Sweet Corn
European corn borer (ECB) moth catches continue to be extremely low around the state. The few remaining infestations are in pre-tassel stage sweet corn. Whorl is largely un-infested with ECB at this time. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 07/07/21 are as follows:
| Blairstown 1 |
| Downer 1 |
| East Vineland 1 |
| Milford 1 |
Sweet Corn
European corn borer (ECB) moth catches have dropped to nearly nothing around the state. Remaining infestations are in pre-tassel stage sweet corn. Whorl is largely un-infested with ECB at this time. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 6/30/21 are as follows:
| Asbury 1 |
| Downer 1 |
| Milltown 1 |
| Oldwick 1 |
