The water in a droplet under 150 microns in size can evaporate in a few seconds in the right conditions. Wind can … See more WebConduct field calibration when spraying the pesticide. Start with the tank full of solution, spray a known distance in the field (at least 3,000 feet) and determine the number of gallons needed to refill the tank. Determine the application rate (GPA) with the following formula. GPA = (gallons sprayed x 43,560) / (Boom width (ft.) x distance (ft.)) WebNew BackPack Sprayer?
