Seventeen sites reporting this week. Eight sites had European corn borer-E (ECB-E) and five sites had ECB-Z. Corn earworm (CEW) was reported at 3 sites, with two of the sites over threshold indicating a need for a spray, please see the chart at the bottom of this page. Fall armyworm (FAW) was reported at 8 sites and 16 sites reported Western bean cutworm (WBC).
Western bean cutworm peaked last week and total number caught in traps is dropping but the total number of sites with WBC remains high. No reports of WBC egg masses seen in the field this week but it is still important to scout fields that are in the whorl or early tassel stage for egg masses. The threshold for processing sweet corn is 4% and a 1% threshold for fresh market sweet corn. Eggs are usually laid on the top side of the first 3 leaves nearest the tassel.
Average sweet corn trap catches for all reporting sites from 8.5.14 to 8.12.14.
