The Fluorescent Tracer (FT) Technique was developed for pesticide applicator safety education, training, and self-evaluation. It was designed for pesticide safety educators, including agricultural extension agents, integrated pest management trainers, farm supervisors, safety managers, and anyone interested in teaching safe farming practices. The technique is a powerful tool for showing pesticide contamination and for helping workers evaluate their practices and protective equipment.

Modern synthetic insecticides, including DDT (dichloro-diphenyl-trichloroethane) came into use in the 1940s. Concerns about the harmful effects of these pesticides were voiced in the entomological and other scientific literature well before Rachel Carson's 1962 book Silent Spring sounded an alarm. Among the concerns were for their broad toxicity which killed beneficial insects and that not enough was known about their effects on plants, animals and soils. Some scientist urged caution and more limited use until research was complete on health and environmental effects. For a good review of this debate, read Professional Entomology and the 44 Noisy Years since Silent Spring at [ Ссылка ] This 1958 film, Health Hazards of Pesticides, was produced by the Public Health Service of the U.S. Communicable Disease Center (CDC). The film emphasizes the potential public health hazards resulting from the widespread use of pesticides and explains the work of the Communicable Disease Center's toxicology laboratories in Wenatchee, Washington, Savannah, Georgia and Chattanooga, Tennessee . The technical advisor, Wayland Hayes was a toxicologist with the CDC who strongly supported the use of pesticides and generally believed the major problem was with misuse and accidental poisonings.
