Sweet Corn

The second European corn borer (ECB) generation continues to be weak. Catches are limited to scattered pockets registering more than one moth per week (see ECB map).

As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.

Sweet Corn

European corn borer (ECB) adult catches have become somewhat more consistent in southern NJ over the past week, but with very few individuals captured north of Burlington County (see ECB map). This late summer flight appears to be a fairly week one. As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.

Sweet Corn

European corn borer (ECB) adult activity has declined somewhat over the past week, with only scattered individuals outside of western Gloucester and Salem Counties (see ECB map). It remains to be seen whether we get another surge in moths as the summer winds down. As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.

Sweet Corn

European corn borer (ECB) adult activity is on the increase, with low catches in parts of the state now. The second adult flight is underway. Areas of highest activity are scattered throughout the state with one notable hot spot in central Morris County (see ECB map).

As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.

European corn borer (ECB) adult activity is stable, with low level activity in parts of the state now. This is the beginning of the second adult flight. Areas of highest activity are still along the Delaware Bay Shore and in central Morris County (see ECB map), but areas between should fill in over the next week.

As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.
