β-Endosulfan solution is primarily used as an insecticide in agricultural practices to control a wide range of pests on crops such as cotton, tea, coffee, fruits, and vegetables. It is effective against pests like aphids, whiteflies, and bollworms, helping to protect crop yields and quality. Additionally, it has been utilized in forestry to manage insect infestations in timber. However, due to its high toxicity and environmental persistence, its use has been restricted or banned in many countries to mitigate harmful effects on non-target organisms, including humans, wildlife, and aquatic ecosystems. Proper handling and application are critical to minimize risks when used in regions where it is still permitted.
