Abstract

South African agriculture is at an intermediate stage of development. It is not as intensive and highly mechanized as in the industrialized countries of North America or Europe but, on the other hand, it is far removed from the subsistence farming practiced in most of Africa. This intermediate stage of development is reflected in the application or use of pesticides1. Organic pesticides have been in use since their development in the mid-1940s,but the proportion of arable land and veld treated and the number of applications per season have never been on a par with western Europe or North America. This may be due to the unpredictable climate experienced by most areas of the country, the greater availability of cheap labor for weed control, or the strict administrative controls that were placed on the sale and use of pesticides in South Africa where a registration scheme was embarked upon in 1947. Although the State has on occasion had to treat large areas of veld for the control of brown locusts, it has not been common practice to spray pastures and forests. Mosquito control has been confined to malarial areas and tsetse fly-infested areas have only been sprayed when absolutely imperative. The lower intensity of pesticide usage in South Africa has thus prevented most of the serious environmental pollution problems encountered in many countries.
