Enter the amount of water in your tank.
This calculates dilution only. Always follow the per-acre application rate; a larger water volume does not change that rate.
At a 1:500 dilution, a 2-gallon container mixes with approximately 1,000 gallons of water. Follow the foliar per-acre rate and crop water-volume needs.
