Hot Dry Weather and Transplant Death

Transplants that are not allowed to harden-off for a few days outside prior to setting in the field may suffer significantly. It is important to expose all transplants to some normal weather conditions before transplanting so they can become acclimated to light intensity as well as the wind and other field conditions.

European corn borer (ECB) adults are being captured with increasing frequency now. At the present, areas of highest activity include Burlington and Warren counties (see ECB map). Cooler nights for later this week may suppress catches for the next several days.

Most early sweet corn plantings are too young to support ECB larval infestations. However, over the next two weeks we should begin to see feeding in the most advanced plantings. Be sure to begin monitoring the earliest plantings for ECB feeding while they are still in the whorl stage. For detailed information see:

 

The highest nightly ECB catches for the previous week are as follows:
Belvidere 2 Allamuchy 1 Port Colden 1
Blairstown 2 Califon 1 Sergeantsville 1
Denville 2 Centerton 1 Tabernacle 1
Medford 2 Pedricktown 1 Woodstown 1
