what is the ratio for a 4 gal sprayer? how many ounces per gallon. I have a bunch of trees 1-6 inches in diameter
For lower volume basal stem applications of Garlon 4 Herbicide to control seedlings, you would use 20-30 gallons of Garlon 4 in enough oil to make 100 gallons of solution. This breaks down to 25-38 oz of Garlon 4 per gallon of oil solution. Per page 7 of the product label under "Low Volume Basal Bark Treatment": Spray the basal parts of brush and tree trunks to a height of 12-15 inches from the ground in a manner that thoroughly wets the lower stems, including the root collar area, but not to the point of runoff.
