One of the functions of the Pesticides Control Authority, under The Pesticides Act, 1975 is the registration of pesticides. A pesticide is defined under the Pesticides Act as 'any product, organism, substance or thing that is manufactured, represented, sold or used as a means of directly or indirectly controlling, preventing, destroying, mitigating, attracting or repelling any pest, and includes-

(a) any compound or substance that enhances or modifies or is intended to enhance or modify the physical or chemical characteristics of a pesticide to which it is added; and

(b) any active ingredient used for the manufacture of a pesticide.'

Registration of pesticide products falls into four categories. These categories include

Pesticides with normal requirements
Pesticides with less stringent requirements
Requirements for re-registration of a pesticide
Procedure for Registration of a Minor Use Pesticide
Procedure to obtain a licence to Sell Restricted Pesticides
Procedure to obtain a licence to Manufacture a Pesticide
