Abuse and misuse of insecticides is common in Africa. Although the use of pesticides in Africa represents less than 5 percent of the global total, misuse is disproportionately high. The use of insecticides is determined largely by export crops, such as cotton and cocoa. Trends are therefore dependent on world prices. Without specific measures, a continued increase in insecticide consumption is likely to be matched by continued misuse. Such chemicals are associated with environmental pollution, human contamination, rising costs, and resistance to development. The following technology describes methodologies relating to technical, regulatory, and policy issues concerning the development and implementation of legislation for registration of biological pesticides in sub-Saharan Africa.
