Fluensulfone is primarily used as a nematicide in agriculture to control nematode infestations in various crops. It is effective against root-knot nematodes, which are known to cause significant damage to plant roots, leading to reduced crop yields. The chemical works by disrupting the nervous system of the nematodes, ultimately killing them. It is applied to the soil either before planting or during the growing season, depending on the crop and the severity of the infestation. Fluensulfone is valued for its ability to protect crops like tomatoes, potatoes, and cucumbers, ensuring healthier plants and improved agricultural productivity. Its use helps farmers manage nematode populations sustainably while minimizing the impact on non-target organisms and the environment.
