Defoliators

  • Defoliator outbreaks can cause significant mortality and growth loss and treatment can be justified on known impacts

  • Operational monitoring and treatment conducted for WSBW and DFTM

  • ESBW and other defoliators cause damage but treatment not justified

  • Annual Budget: $843,000 for Btk treatments
