To promote plant development and enhance agricultural yield, farmers utilise a variety of agrochemicals. Insecticides, herbicides, fungicides, weedicides, and other pesticides are among the agrochemicals. The agrochemicals and their classification are mentioned in this chapter. The pros and cons of agrochemicals are also discussed in the report. Focus is also placed on how agrochemicals affect the ecology and how they work. Included are the risks and protective measures related to the usage of agrochemicals. These crucial agrochemical issues will be covered in full in the study. Future research into the molecular basis of agrochemical mechanisms must be done.
