What is the correct usage rate of Bifen XTS when treating mountain pine beetles using a 2 gal sprayer?
I am using a 2 gal sprayer & need the correct ratio of Bifen xts to water.
When treating for mountain pine beetles the product label recommends using 2.0 pints of product per 100 gallons of water. If you only need to mix 2 gallons at a time you will 0.64 oz of Bifen XTS diluted in 2 gallons of water. Treat the main trunk from the base of the tree to at least halfway into the live crown spraying the tree directly and until the bark is completely wet (usually 1 to 4 gallons of spray per tree). Be sure to read the Bifen XTS product label for complete usage instructions.
