WNY Sweet Corn Trap Network Report 9.20.11

ECB counts were uniformly low this week at all locations still reporting.  Corn earworm numbers are down from last week, but remain very high at a couple of locations.  The few remaining fields will be very attractive to egg-laying females, so sprays need to be continued until a week before harvest where numbers warrant.  Remember that a day can be added to the intervals in the table below, because of the lower temperatures.  Fall armyworm are being caught at most locations in moderate numbers.
