β-Endosulfan solution is primarily used as an insecticide in agricultural practices to control pests on a variety of crops, including cotton, tea, and fruits. It is effective against a broad spectrum of insects, such as aphids, whiteflies, and beetles, helping to protect crops from damage and improve yield. In addition to agriculture, it has been utilized in forestry to manage pest infestations in trees. However, due to its high toxicity and environmental persistence, its use is heavily regulated or banned in many countries to prevent harm to non-target species, including humans, wildlife, and aquatic ecosystems. Proper handling and application are crucial to minimize risks to the environment and public health.
