Fenthion solution is widely used in agriculture as an effective insecticide to control a variety of pests that damage crops. It is particularly effective against sucking and chewing insects, such as aphids, leafhoppers, and beetles, helping to protect fruits, vegetables, and other plants from infestations. In addition to agricultural use, it is also employed in public health programs to combat disease-carrying insects like mosquitoes, which can spread malaria and other illnesses. Fenthion solution is applied through spraying or fogging methods, ensuring targeted pest control. However, its use requires careful handling due to its toxicity to non-target organisms, including beneficial insects, birds, and aquatic life. Proper application and adherence to safety guidelines are essential to minimize environmental impact.
