Detailed explanation-1: -DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.
Detailed explanation-2: -DDT 1 is an organochlorine2 insecticide that was first synthesized in 1874 (1, 2). • DDT was a commonly-used pesticide for insect control in the United States until it was canceled in 1972 by the United States Environmental Protection Agency (EPA).
Detailed explanation-3: -Today, DDT is only used in certain countries, mainly to kill mosquitoes that cause malaria. DDT poses a risk to people and wildlife because it takes many years to break down in the environment. The insecticide also builds up in animals’ bodies.
Detailed explanation-4: -Through GEF funding, India has taken the first step to eliminate dependency on the insecticide DDT by promoting locally appropriate, cost-effective, and sustainable alternatives, including the Long-Lasting Insecticidal Net (LLIN) and Neem-based and bacteria-based biopesticides.
