Abstract: Organophosphorus pesticides are a critical class of agricultural chemicals that play a significant role in pest and disease control and in enhancing crop yields. However, their widespread use has also led to serious environmental concerns and potential health risks, prompting the ban and discontinuation of many products. Despite these challenges, organophosphorus pesticides continue to be favored for their high efficiency, low cost, and ease of production. A few types remain essential in agricultural practices, particularly in less-developed regions where their use still holds potential for growth. This article provides a comprehensive review of the development, current status, and future prospects of organophosphorus pesticides.
