Silafluofen is primarily used as an insecticide in agricultural settings. It is effective against a range of insect pests, especially those that affect crops such as rice, vegetables, and fruit trees. It works by disrupting the nervous system of insects, leading to paralysis and death. Due to its high lipophilicity and stability, it adheres well to plant surfaces and provides prolonged protection. It is often applied in low doses because of its high potency, reducing environmental impact. Silafluofen is particularly useful in integrated pest management programs where selective control of pests with minimal harm to beneficial insects is desired.
