Technical Abstract: Pesticide manufacturers spend large amounts of time and money to determine the recommended application rate for pesticides. The recommended rate must be large enough to control the target pests under most field conditions, but must be as low as possible so use of the pesticide is as economical as possible for the farmer. The effect of pesticides are greatly influenced by ythe method and timing of application and the operation and accuracy of the equipment used. Applying too little pesticide causes ineffective pest control that may require the added expense of respraying. Applying too much pesticide adds to the cost, may damage the crop, and may lead to environmental pollution. Labels on pesticide containers indicate proper application rates. However, these rates can be achieved only if the application equipment is suitable for the job, calibrated frequently, and operated properly. Now, more than ever before, applicators need to do a better job of spraying because pesticides are more potent and require more precise application. An applicator has to consider at least the six major factors to achieve best results from a pesticide application. These factors are: 1) know the exact volume of the tank, 2) carefully calculate how much pesticide to add to the tank, 3) measure the ground speed, 4) consider the influence of soil type and soil conditions on the amount of pesticide needed, 5) make sure the pressure gauge is working properly, and 6) calibrate the sprayer and make sure the coverage across the field is uniform.
