Can I mix 2oz/gal of Monterey insect spray with 1oz/3gal of BT??
Monterey B.t. Insecticide? is an organic OMRI rated insecticide and should not be mixed with any other insecticides. Doing so would change its formula and composition and it would not longer work as intended. Monterey B.t. Insecticide is mixed at 1.5 oz. per 3 gallons of water per 1,000 sq. ft. for Fruits and Vegetables and 2 oz. per 3 gallons of water per 1,000 sq. ft. for Ornamentals.
