Spraying of Pesticides

26.1 Spraying of Pesticides Spraying utilizes equipment which turns liquid pesticide into a fine spray or mist.

Advantages: It is preferable for horses because they are easily injured in a dip. Spraying is more gentle than dipping, and recommended for valuable stock, heavily pregnant cows, cows with big udders, and weak animals. Because the necessary equipment costs less than a dip vat, and smaller volumes of pesticide are used, spraying is more cost effective when small numbers of animals need to be treated.

Disadvantages: Because spraying takes time for each animal, it is difficult to use for large herds or flocks. In addition, it is easy to miss some spots on an animal during the spraying process. Approximately ten liters of spray is needed per animal for large cattle and horses to completely wet the coat.
