Sweet Corn
Increasing numbers of European corn borer (ECB) moths have been captured this
past week, but still relatively few moths overall. At present, the highest activity is on the Cumberland-Atlantic border, with minor concentrations in Salem and northern Burlington counties (see ECB map). As early sweet corn plantings progress through whorl and pre-tassel stages, feeding from this pest may be detectable. Look for the characteristic “shot-hole” type of feeding (photo at right) and consider treating when infested plants exceed 12% in a 50 plant sample.
The highest nightly trap catches of ECB for the week ending 5/30/18 are as follows:
East Vineland 2 | Centerton 1 | Eldora 1 |
Allentown 1 | Cinnaminson 1 | Medford 1 |
Belvidere 1 | Crosswicks 1 | South Branch 1 |
Califon 1 | Denville 1 | Woodstown 1 |
