Organic Farm Advisory
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.

IPM Update 6/27/18
Sweet Corn
European corn borer (ECB) moth catches in black light traps remain very low. There will be no map in this edition due to insufficient catch. Incidents of feeding are declining as infested plantings proceed to silk and whorl stage corn has not been exposed to egg laying. We should be in a period relatively free of whorl infestations now. The next whorl infesting pest will be fall armyworm (FAW). As yet, no infestation of this pest have been detected. [Read more…]

IPM Update 6/06/18
Sweet Corn
European corn borer (ECB) moths continue to be captured in black light traps, but numbers are low overall. Activity has shifted northward, with the highest activity now from Mercer County northward (see ECB map). Despite these low adult numbers, IPM technicians have reported dramatic increases in feeding in whorl stage plantings in the central and northern counties. Numbers of infested plants have reached 40% in the Somerville area, and 30% near Sparta in Sussex County. In many cases, nearby farms exhibit little or no feeding in similar stage sweet corn, so these elevated infestation rates can be highly localized. [Read more…]
