Biopesticides For a Better Environment

Often the use of several synthetic and artificial pesticides is harmful to beneficial insects, domestic animals as well as human beings. Biopesticides can serve as an effective measure in protecting plants without affecting the ecosystem.

Biopesticides are certain types of pesticides which are derived from natural materials such as animals, plants, bacteria and certain minerals. They work by activating the natural systems in plants and insects to work as pesticides.

Microbial pesticides for example consist of a microorganism like fungus, virus, or protozoa that have natural abilities to control the growth of certain weeds or to kill specific insects.

Sometimes plants are injected with genetic material that produces the substance which destroys the pest, for example, the gene for the Bt pesticidal protein is introduced into the plants genetic material.

Biochemical pesticides are naturally occurring substances such as insect sex pheromones which interfere with mating and thus help to reduce the insect population.

To know more about the benefits of biopesticides on the environment, you can refer to the various books published by the National Institute of Science and Media.

Joel Ball, the lead author on the various titles published under the NISM name is a renowned figure in the scientific and publishing circle.
