7/20/2021 Plans to Re-spray Briars in the North Fields
For blackberry and dewberry control in pastures see this aces.com paper. It recommends 2 pints of Remedy Ultra per acre. Converting that to a spot spray rate anticipating 1 gallon of liquid spread over 1,000 SF results in the following.
2 pints per ac = 4 cups per ac = 16 tbsp x 4 cups = 64 tbsp for 43.56 k SF = 1.47 tbsp/1000 SF
So: ~1.5 tbsp/KSF or ~1.5 tbsp/gallon spot-sprayed over 1 KSF = 1/4 cup in 2 gallons of water = 1 cup in 8 gallons of water. The label indicates that level will also kill the remaining Chinese Tallow trees.
Mix with 2,4-D Amine at 1 oz. per gallon, i.e. per 1,000 SF. For 8 gallons of water add 8 ounces of 2,4-D.
Add the non-ionic surfactant at 1 Tbsp per gallon added 8 Tbsp (4 oz.) for the 8 gallons of mix.
