How much 24d is in a 15 gallon sprayer?

The amount of 2,4-D in a 15-gallon sprayer depends on the desired concentration and the specific product's formulation. For example, if you're aiming for a 1% solution, you would add 1.5 pints of a 2,4-D product that is 4 pounds per gallon. Always refer to the product label for precise mixing instructions based on your target application rate.
