BIFENTHRIN APPROVED AGAINST BMSB IN THE HUDSON VALLEY FOR 2015

New York’s Section 18 application for the use of products containing bifenthrin has been approved by the EPA. This is a renewal by 

the EPA and NYS DEC of a ‘Section 18 Emergency/Crisis Exemption Approval’ use permit for the pyrethroid bifenthrin to control brown marmorated stink bug on apples, peaches, and nectarines this year. The regional application request was submitted to EPA from the mid-Atlantic states of DE, MD, NC, NJ, PA,VA, WV and NY state.



Bifenthrin is one of the most effective insecticides for use against the brown marmorated stink bug (BMSB). Its use is limited to Columbia, Dutchess, Orange and Ulster Counties of NY. Upon determining the presence and trap threshold for BMSB in counties where the pest has caused injury to fruit in the past, applications of bifenthrin should be considered as the first step in managing the insect, taking into account the 30-day interval between applications. Consider a first application to be made along the orchard edge, bordering deciduous woodland and hedgerow or clusters of host trees such as catalpa, black locust, Tree of Heaven, maple, or ash. The need for a second application can be triggered as the insect is observed on fruit and/or captured in pheromone traps using 10 BMSB adult per trap per week as indicated by the EDDMaps.org site or trap presence on site.

Bifenthrin is a pyrethroid sold under the trade names of Brigade WSB (10% bifenthrin, EPA Reg. No. 279-3108, FMC Corp.), Bifenture EC (25% bifenthrin, EPA Reg. No. 70506-227), and Bifenture 10DF (10% bifenthrin, EPA Reg. No. 70506-227, United Phosphorus Inc.). 

 Regardless of the product used, a maximum of 0.08 to 0.2 lb[AI]/acre/season will be allowed, with no more than 0.5 lb a.i./acre applied per year with multiple applications made at a minimum of 30 day intervals; a restricted entry interval (REI) of 12 hours and pre-harvest interval (PHI) of 14 days must be observed.

 When applying either of these materials for BMSB control on apples, peaches, or nectarines, growers must have possession of the Section 18 label. Presently the 2014 label is available at: 
(http://pmep.cce.cornell.edu/regulation/sec18/2014/index.html). The 2015 labels will be posted as soon as they are made available.
