Pest control programs pesticides

The ability of pests to resist poisoning is called pesticide resistance. Consider this when planning pest control programs that rely on the use of pesticides.

The need for pest control in tropical crops is definitely on the increase, and this is brought out in the papers of this symposium. These by no means cover this important subject. Omission of discussion of many crops from this program does not depreciate their importance, but time does not allow their inclusion. Literature on pesticide control of tropical crops is accumulating in many scattered publications—for example, tea culture has been adequately covered by Lamb and others in World Crops for May 1954. It is hoped that this symposium will pave the way for future discussions of this important subject. Pest control in tropical agriculture is a challenge to both the scientist and the manufacturing chemist. 

Whenever applied, IPM practices have consistendy resulted in decreases in insecticide applications of 50 to 90% over conventional spray programs. By encouraging natural enemies, IPM practices markedly decrease the rigor of natural selection by pesticides that is responsible for resistance. Natural enemy preservation also prevents the great fluctuations and suiges in insect pest populations observed after the injudicious use of broad-spectrum insecticides. Under the IPM concept, insecticides are generally used when other practices are inadequate and the pest population reaches the economic threshold. In order to make the IPM concept effective, insecticides must be used as selectively as possible, with minimal disturbance to all other elements of the ecosystem. Thus IPM practices are essentially blueprints for the proper use of insecticides in insect pest control. 

The Special Registration Program responds to unexpected and temporary pest control problems and supports state governments in registering pesticides for intrastate use. 

Chlorinated hydrocarbon pesticides are widely used in agriculture, stmctural pest control, and malaria control programs around the world. Lindane is used medicinally for the treatment of lice and scabies. Chlorinated hydrocarbons are of major toxicologic concern, and many (eg, DDT and chlordane) are now banned from commercial use because they persist in the environment and accumulate in biologic systems. In 2002, sale of lindane was banned in California.
