Twenty sites reported this week for Western NY. European corn borer (ECB)-E was caught at nine sites and ECB-Z was caught at seven sites this week. Corn earworm (CEW) are beginning to increase with eight sites reporting trap catches this week, with six sites high enough to require a 4, 5, or 6 day spray schedule (see table at bottom of post). Fall armyworm (FAW) numbers are increasing and were caught at eleven sites. Western bean cutworm (WBC) seemed to have peaked last week and are now declining (see graph below) but there were still 17 sites reporting trap catches. Trap catches from only two sites for Eastern NY were available at this time but the remaining ones will be updated as they come in. Please see the bottom of this post for a table of Eastern NY trap catches.
Where CEW are being caught in high enough numbers to determine the spray schedule (see the chart below), 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.
Average sweet corn trap catches for all reporting sites from 5.31.16 – 8.9.16
