Rhetorical and practical commitment to pesticide use in developing
countries is frequently well established especially to broad-spectrum
compounds such as organophosphates and carbamates that are noted
for their acute toxicity. These products remain attractive to farmers in
part because they are no longer under patent protection and are thus
considerably cheaper than many newer products. Indeed many pesticides
that have been prohibited in developed countries are still produced
and sold in developing countries, either by domestic companies
or by multinationals acting through subsidiaries or joint ventures
