Parathion-methyl solution is widely used in agriculture as an effective insecticide to control a variety of pests on crops such as cotton, fruits, vegetables, and cereals. It targets insects like aphids, mites, and leafhoppers by inhibiting their nervous system, ensuring crop protection and improved yields. Additionally, it is applied in stored grain management to prevent infestations. Due to its high toxicity, it is essential to follow strict safety protocols during handling and application to minimize risks to humans, animals, and the environment. Its use is regulated in many countries to ensure responsible and limited application.
