What are synthetic pesticides?

Synthetic pesticides are man-made chemicals designed specifically to kill or repel pests. They are used mainly in agriculture, though their use is not limited to the field but also in other industries and also for domestic use. The use of synthetic pesticides began in the United States of America (USA) in the 1930s.

What are the two major kinds of synthetic pesticides?

The two largest classes of synthetic pesticides are insecticides, which are designed to kill insects, and herbicides, which are designed to kill plants. Other classes of pesticides include fungicides (for molds and fungi), rodenticides (for mammals), and antimicrobials (for microorganisms such as bacteria and viruses).

What are natural and synthetic pesticides give one example of each?

They can be made from natural sources, such as pyrethrin insecticide extracted from certain chrysanthemum plants. Another example is azadirachtin, an extract from the neem tree. Pesticides can also be made synthetically, as in pyrethroids, which control insects as pyrethrins do.

Is DDT synthetic?

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.

What type of synthetic chemicals are used in agriculture?

What is synthetic organic insecticides?

The synthetic organic insecticides are relatively new compounds. The first synthetic organic insecticide DDT was synthesized in 1874, and its insecticidal properties were first recognized in 1939. During World War II, research in nerve gases led to the discovery of additional compounds that are effective insecticides.
