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.

Sweet Corn

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.

Sweet Corn

European corn borer (ECB) adult activity is starting to increase in parts of the state now. This is the beginning of the second adult flight. Areas of highest activity are currently 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.

Sweet Corn

There is still very little European corn borer (ECB) adult activity at this time. Few individuals have been captured throughout NJ this past week (see ECB map). ECB infestations are absent from sweet corn plantings. We would expect to see signs of the second flight within the next week or so.

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

We are still between European corn borer (ECB) adult generations at this time. Very few individuals have been captured throughout NJ this past week (see ECB map). ECB infestations are almost gone from all sweet corn plantings. We would expect to see signs of the second flight within the next two weeks.

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

We are between European corn borer (ECB) adult generations at this time. Only scattered individuals are being captured throughout NJ (see ECB map). ECB infestations are still present in some sweet corn plantings, but whorl stage corn is now largely free of ECB injury.

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.
