Eighteen sites reported this week for Western NY. European corn borer (ECB)-E was caught at five sites and ECB-Z were caught at six sites. Corn earworm (CEW) are still increasing with twelve sites reporting trap catches this week. Eleven of the CEW catches were high enough to require a 4, 5, or 6 day spray schedule (see table at bottom of post). Fall armyworm (FAW) was caught at fourteen sites and Western bean cutworm (WBC) was caught at ten sites this week. Please see the bottom of this post for a table of Eastern NY trap locations.
Average sweet corn trap catches for all reporting sites from 5.31.16 – 8.23.16
Both CEW and FAW increased this week. At sites 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 that FAW and other pests are not above threshold.
