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.

Sweet Corn

Fall armyworm (FAW) infestations in whorl stage plantings in northern and central counties have dropped to very low levels.    This may not be the case in southern counties.  Growers are advised to check whorl and seedling stage corn plantings weekly for signs of FAW.  Consider treating if infestation rates exceed 10%.  This pest is capable of significant injury to sweet corn plants, resulting in severe stunting and failure to produce viable ears.  Note that growers of Attribute II type genetically engineered corn are unlikely to see damage from FAW.

We will provide updates on new FAW appearances and severity as reports come in.  FAW are resistant to synthetic pyrethroids.  Effective sprays should include IRAC grp. 5 (spinosyns) or IRAC grp. 28 (diamides).  The carbamate (IRAC grp. 1A) Lannate is also still effective.  Sufficient water should be used in the applications to allow the solution to penetrate the layer of droppings that may have formed above the caterpillar.

Fall armyworm (FAW) infestations in whorl stage plantings remain a presence, although in many scouted fields in northern and central counties, the incidence of FAW has declined.  Re-infestation rates are fairly low, even in coastal areas.    This may not be the case in southern counties.  Growers are advised to check whorl and seedling stage corn plantings weekly for signs of FAW.  Consider treating if infestation rates exceed 10%.  This pest is capable of significant injury to sweet corn plants, resulting in severe stunting and failure to produce viable ears.  Note that growers of Attribute II type genetically engineered corn are unlikely to see damage from FAW.

Fall armyworm (FAW) infestations in whorl stage plantings remain a presence, although in many scouted fields in northern and central counties, the incidence of FAW has declined.  Treated fields are not typically experiencing re-infestation.    This may not be the case in southern counties.  Growers are advised to check whorl and seedling stage corn plantings weekly for signs of FAW.  Consider treating if infestation rates exceed 10%.  This pest is capable of significant injury to sweet corn plants, resulting in severe stunting and failure to produce viable ears.  Note that growers of Attribute II type genetically engineered corn are unlikely to see damage from FAW.

Sweet Corn

 Fall armyworm (FAW) infestations in whorl stage plantings remain a presence.  In scouted fields, some infestations in whorl corn are in excess of 20%, and are likely much higher in the southern coastal areas.   Growers are advised to check whorl and seedling stage corn plantings weekly for signs of FAW.  Consider treating if infestation rates exceed 10%.  This pest is capable of significant injury to sweet corn plants, resulting in severe stunting and failure to produce viable ears.  Note that growers of Attribute II type genetically engineered corn are unlikely to see damage from FAW.
