Interpretive Summary: Pesticides are applied to nearly all commercial potato crops to help manage nematodes, insect, weeds, and diseases. In order to obtain the maximum effect of a pesticide, the proper application method should be used. Pesticides are most commonly applied by ground rigs, aircraft, and through irrigation systems (chemigation). Each method has unique advantages and shortcomings depending on the pesticide and target pest. Considerations for choosing the most effective and appropriate application method for herbicides, fungicides, insecticides is outlined. Factors such as, spray coverage, droplet distribution, penetration in canopy, and carrier volumes impact pesticide effectiveness and require a thorough understanding in order to make proper decisions when choosing pesticide application methods. Comparisons of application time, cost, labor, and drift potential of different application methods are also presented.

Technical Abstract: Pesticides are an important component of most management programs for nematodes, diseases, weeds, and insects that impact yield and/or quality in potatoes. The appropriate pesticide, correct timing of application, effective rate, and appropriate method of application must be selected for effective pest control. Three major methods of applying pesticides; ground, aerial, and through irrigation systems (chemigation) are utilized by potato growers and are discussed in this chapter. Considerations for choosing the most effective and appropriate application method for herbicides, fungicides, insecticides is outlined. Factors such as, spray coverage, droplet distribution, penetration in canopy, and carrier volumes impact pesticide effectiveness and require a thorough understanding in order to make proper decisions when choosing pesticide application methods. Comparisons of application time, cost, labor, and drift potential of different application methods are also presented.
