Formulations of Insecticides
The majority of insecticides are applied as sprays, dusts, granules, microcapsules, vapors, aerosols, or seed dressings. After an insecticide is manufactured in a relatively pure form ( technical grade), it must be formulated before it can be applied. Formulation is the processing of a compound by such methods that will improve its properties of storage, handling, application, effectiveness and safety to the applicator and the environment, and profitability. Formulation is the final physical condition in which the insecticide is sold commercially. In most cases, it must be diluted according to the formulator’s instructions before use. The price for a given weight of chemical depends largely on the type of formulation, the most expensive being the pressurized aerosol.
