Twenty-six sites reporting this week. European corn borer (ECB)-E was caught at six sites and ECB-Z was caught at two sites. Six of the ten sites reporting corn earworm (CEW) were over threshold, indicating a need for a spray, please see the chart at the bottom of this page to determine the correct spray interval for your field. Fall armyworm (FAW) was caught at five sites and Western bean cutworm (WBC) were caught at five sites this week.
Below is a graph showing the average trap catch for all reporting sites since the beginning of the trapping season. Average trap catch numbers for all species is low to date. In the next few weeks I am expecting WBC and FAW to increase. WBC usually peaks the last week of July into early August.
Average sweet corn trap catches for all reporting sites from 5.28.19 – 7.16.19.
Degree day accumulations for sweet corn trap sites range from 702-1187 (base 50F) with an average of 935. WBC emergence is predicted to be at 50% when degree day accumulations reach 1422 (chart below). With the cool spring we are still below the predicted 25% emergence for all sites.
