Stink Bugs Still a Threat to Cotton

Article by Jack Bacheler

Stink bugs remain a potential threat in many areas of NC, both because of our generally late crop and high proportion of susceptible bolls and due to high stink bug populations, although exceptions of “cut-out” cotton where stink bugs are no longer a threat are also common. Because stink bug levels vary so much from field to field and across the agricultural landscape, opening and inspecting the inner surface of soft 1-inch diameter or quarter-sized bolls is needed to determine if a spray is needed. Remember to use a protective 10% internal boll damage threshold during weeks 3 through 5 of the bloom period, probably extending this 10% threshold into week 6 this year.
