Ultra-Low Volume (ULV)

The term Ultra-Low Volume (ULV) (spraying) is used in the context of pesticide application.
Ultra-low volume 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.
ULV spraying is a well-established spraying technique and remains the standard method of locust control with pesticides in Malaysia. It has also been used in massive aerial spraying campaigns against disease vectors such as the tse-tse fly and bed bugs.
