In Kenya, the Pest Products Control Board (PPCB) is responsible for importation and use of pesticides in the country. Between 1985-1987, pesticides worth US $69 million (Ksh 1732.3 million) were imported into the country (Mwanthi and Kimani 1993), while between 1987-1990, a total of 31,234 tons of pesticides (PPCB 1994) were imported. Pesticides are used to control pests for crops like coffee, corn, cotton, and in public health they are used to control disease vectors such as, malaria and yellow fever carrying mosquitoes (Mwanthi and Kimani 1993).
