The threshold for stink bugs in corn is changing based on recent research conducted in both North Carolina and Virginia. These studies indicated that, while seedling thresholds were effective, there was evidence that the pre-tasseling and early reproductive stages threshold should be lowered. We also shortened the period that stink bugs needed to be controlled from R4 to R2, since there is no evidence that brown stink bugs can cause economic yield loss (except, perhaps at very high levels) past R2. New thresholds are listed on our website.
