Thirty-three sites reporting this week. European corn borer (ECB)-E was trapped at fourteen sites and ECB-Z was trapped at five sites. Corn earworm (CEW) was trapped at sixteen sites, with ten sites high enough to be on a 4, 5, or 6 day spray schedule (see chart below). Fall armyworm (FAW) was trapped at thirteen sites and Western Bean cutworm (WBC) was trapped at thirty sites this week.
Where CEW are being caught in high enough numbers to determine the spray schedule, those applications will be sufficient to take care of other worm pests that are present. Where CEW are not determining the spray schedule, scout to be sure other pests are not above threshold. Click on the scouting and thresholds information link to the right for more information.
Below is a graphical representation of moth emergence for the season. All reporting sites have been averaged to show the general trend for the 5 moth species for NY from May 23 to August 1 (please see the map for site locations). Western bean cutworm is clearly still on the rise and will probably peak in the next week or two.
Average sweet corn trap catches for all reporting sites from 5.23.17 – 8.1.17
