Abstract
Pesticides are chemical compounds that are toxic and are used to control different types of pests and uncontrolled growth of weeds for plant protection in crop production and food storage. A large number of pesticides are being used all over the world. Pesticides play a great role in food security. Crop production has been increased by controlling insect attack, removing weeds by herbicides, controlling crop loss by rodenticides. To get a high yield of products, a higher amount of fertilizers is also needed. The growth of plants is associated with the growth of weeds by which nutrients for the plants are consumed by herbs. So higher amounts of herbicides are also needed to remove herbs as traditional weed removal by humans has become expensive. The residue of pesticides in the foodstuff is reducing food safety as well as a threat to the environment. Pesticides are ubiquitous in the environment and are found in air, soil, and water. Judicial and sustainable use of pesticides is required for food security and ensuring a healthy environment.
