Banded Application Using Two Nozzles Per Row: Postemergence-directed Active ingredient in % You then spray the . Rinse the containers three times, and pour the rinsate into the tank before finishing the fill. Use the following formula to convert the broadcast output into the banded output: [broadcast output (L/ha) x travel speed (km/h) x (swath width (cm) number of nozzles per swath)] 60,000 = nozzle output (L/min)[100 L/ha x 8 km/h x (50 1)] 60,000 = 0.67 L/min, For completeness, heres the US formula:[broadcast output (gal/ac) x travel speed (mph) x (swath width (in) number of nozzles per swath)] 5,940 = nozzle output (gal/min).

Quantity of material required per hectare = ----- X 100. The active ingredient must then be converted to the actual product. However, questions still exist on how the Maximum Return to Nitrogen (MRTN) rate affects yield and profitability on individual farms. Now multiply the area you want to spray (step 1) by the rate (step 2). How Do I Calculate The Area To Be Treated? 0000000854 00000 n For boom sprayers, the application rate is usually given in gallons per acre (GPA). Email: pested@unl.edu 0000011528 00000 n Gallons of spray mixture = application rate (gallons per acre) area to spray (acres) Therefore, put (20 12 =) 240 gallons of pesticide and carrier in the tank. Step one; select the proper pesticide and application equipment; step two, determine the size of the treatment area; and step three, determine the correct amount needed. Since the application rates and the pounds of active ingredient per gallon are identical for each formulation, the amount of active ingredient applied would be the same for each formulation. The second label recommendation not only requires proper calibration and operation of the sprayer, but it also requires that the spray mixture contains the right concentration of the actual product applied. Keep in mind that acres sprayed in the equation above is the acres driven over (includes any overlap). Equipment calibration involves the same three steps, regardless of the equipment or pesticide used. 0000004108 00000 n You may be familiar with other formulae for calculating your output.

Yes, watch your units: Multiply the area you have left to spray (Step 5) by the sprayer output (determined through calibration). ft. This means only a portion of the field or orchard/vineyard floor receives spray, so the total amount of product applied per hectare (or per acre) should be less for banded than for broadcast. Therefore, when using wettable powders, make a slurry in a separate container and then add the slurry to the tank to ensure good mixing. Pesticides for aquatic weed control may be recommended at certain rates per surface acre, concentrations in the treated water column, and percentage dilution mixed with water in the spray tank. f. The application rate for any given area: Labels give two types of application rates: volume of spray mixture (pesticide and water) applied per unit area (gallons per acre, ounces per 1,000 square feet, etc. Step Two: Establish sprayer settings Spray Tank Capacity (L) = total capacity of the sprayer tank.
