Applications of pesticides must reach their intended targets. Matching the application technique to the crop, the pest, and the pesticide is critical, for example, the use of low-volume spray equipment can considerably reduce overall pesticide use and operational costs. [3]

Ultra-low volume (ULV) application of pesticides has been defined as spraying at a Volume Application Rate (VAR) of less than 5 L/ha for field crops or less than 50 L/ha for tree/bush crops. VARs of 0.25 – 2 L/ha are typical for aerial ULV application to forest or migratory pests.
A pesticide is a substance or a mixture of substances used for killing pests: organisms dangerous to cultivated plants or to animals.The term applies to various pesticides such as insecticide, fungicide, herbicide and nematocide.
