This should already have been done when choosing an even set of nozzles. Regular calibration ensures the right amount of chemical will be applied to the target without costly wastage. How much is needed for a4800 square foot area? As every sp rayer has a different capacity, different nozzles with higher or lower output, a different operator who works at a different speed and pumps at a higher or lower pressure, calibration is the only answer. Introduction. To determine how much pesticide or fertilizer is needed to do a job, first calculate the size of the area to be treated. Calibration for treating small land areas. Calculate the volume of spray tank (if you don’t know it from the handbook): For square or rectangular tanks: Text and illustrations in this module are derived from a 70-page booklet entitled “Pesticide Applicator’s Handbook”. calculations. Nozzle material is important in reducing inaccurate applications due to nozzle wear. A pesticide label specifies that the product be applied at a rate of 5 pints per acre in a spray volume of 30 gallons per acre. Adjust travel speed if the measured output varies by more than 10 percent, but less than 25 percent. Students should be made aware that calculators must be calibrated just like other instruments. If output varies by more than 25 percent, change nozzles and repeat the pre-calibration and calibration processes. To determine the use rate in ounces, again To utilize the TeeJet Nozzle Calculator use this link: TeeJet Nozzle Calculator. The Fertilizer calculator has entries for N, P, K. values, Rate of Application, Area of Application and Cups and Pounds conversions. Using just the right amount of pesticide and fertilizer minimizes the potential for personal, property, or environmental damage and maximizes consumers' return on the dollar. 23.1 gallons per acre X 24 acres = 554.4 gallons. The average nozzle output is 44 OPM or 0.34 GPM (44/128). The 1/128 acre method is a simplified form of calibration based on spraying 1/128 acre. This requires preparation and dilution of stock solutions, the accuracy of which can be increased significantly by using gravimetric methods instead of volumetric. Step 1. Recalibrate the sprayer every 10 hours of operation or anytime there is a change in the pesticide formulation. As every sp rayer has a different capacity, different nozzles with higher or lower output, a different operator who works at a different speed and pumps at a higher or lower pressure, calibration is the only answer. Banding and directed crop foliar applications require a change in the value used for “W” in the formula. The less solution that is leftover, the less there is that has to be disposed of. Calibration of Hand-Held Calculators | Journal of Chemical Education ACS The first approach deals with MU estimation based on intra-laboratory QC data for individual pesticides in a commodity group. The majority Calculation of pesticide in spray tanks. Choose a calm, cool day to make applications to the lawn or garden in order to avoid movement (drift) of the material onto non target areas. The low setting and brisk pace will necessitate covering the area twice, thus guarding against depletion of the measured product before the total area is covered. At 5 pints per acre, the amount of pesticide needed is 120 pints. However, the MG may encounter more complex conversion when working with products such as:  wettable powders, emulsion concentrates, dry and water based products and soluble solutions.
