Kudzu Bug Found on Soybeans in Henderson County

Kudzu bug has moved into soybean fields in Henderson County in the past few weeks, some of which were flowering. So far, kudzu bug has been relatively easy to kill with insecticides (except with neonicotinoid insecticides), but will often reinvade. A preliminary economic threshold, based on Georgia data, is one bug per sweep with large nymphs present, or three bugs per plant with large nymphs present. This is the threshold that we will be using in our state until more information is gathered. Like stink bugs, this insect seems to invade the field edges first, so be sure to scout entire fields.
