The Biopesticides program serves as an information source on biopesticides, biologically based products such as semiochemicals and microbial agents, used by State and Private Forestry staffs, nationwide, for short-term control of pest species. The program is instrumental in coordinating support for advancing the development of biopesticides for use in limited markets such as forestry. We also help coordinate support for the development and advancement of biopesticides as part of integrated pest-management programs.`
The focus of the FHTET-Biopesticide Program is to demonstrate a strong leadership role in the development and implementation of biopesticide technologies to manage invasive species.

The FHTET-Biopesticide Program benefits managers by:

  • Increasing awareness of technology on the use of biopesticides, via publications and FHTET-sponsored workshops, training sessions, and scientific meetings
  • Forming partnerships and coordinating the development and implementation of biopesticide technologies

FHTET has co-sponsored seven meetings, "Emerald Ash Borer National Research and Technology Development": FHTET-2011-06, 2010-01, 2008-07, 2007-04, 2005-16, 2004-02

Ongoing development areas are:

  • Coordinating the production of Gypchek (the gypsy moth nucleopolyhedrovirus) by private industry
  • Optimizing Gypchek and TM-biocontrol-1 (the Douglas-fir tussock moth nucleopolyhedrovirus) for operational use
  • Coordinating the use of Gypchek as part of the Gypsy Moth Suppression, Eradication, and Slow-the-Spread Program
  • Maximizing efficacy of spinosad and Bt toxins for landscape treatment of emerald ash borer
  • Maximizing efficacy of entomopathogens for landscape treatment of hemlock woolly adelgid
  • Developing herbicides for invasive plants
