To date we have seen very low brown marmorated stink bug (BMSB) adult trap captures that are well below threshold for management. However, scouting for the insect in trees has shown BMSB nymphs in late stages of development with adults emerging.
The presence of eggs and early instar nymphs found over the next few weeks may indicate the development of a second generation of BMSB this season. If this occurs we will begin to see high numbers of BMSB moving into crops at which point orchard management for the pest should begin.
One of the most effective tools for use to manage BMSB is the active ingredient bifenthrin in a number of formulations.
Bifenthrin has a 12 hr. re-entry interval, 14 day pre-harvest interval and a 30 day re-application interval.
We received notice by the EPA that they approved the Section 18 application for bifenthrin for use against the brown marmorated stink bug for 2019. Links below provide access to PDF copies of the Section 18 labels for materials containing the A.I. bifenthrin.
Labels should be made available to the applicator during bifenthrin applications. These can be printed or available as digital files such as PDF’s on tablets or smart phones. We were able to approve a total of 7521 treated acres for 2019 for use in apple, peach and nectarines. The exemption is valid now through October 15th as a “Section 18 EXEMPTION, FOR DISTRIBUTION AND USE ONLY IN Columbia, Dutchess, Orange, Ulster, Monroe, Orleans, Wayne and Niagara Counties this year. Use in any other counties is prohibited. in New York State”.
