Chlorfluazuron is widely used in agriculture as an insect growth regulator, particularly effective against lepidopteran pests such as bollworms, armyworms, and diamondback moths. It works by inhibiting chitin synthesis, disrupting the molting process of larvae and preventing them from developing into adults. This makes it a valuable tool in integrated pest management programs, especially in crops like cotton, vegetables, and fruits. Its targeted action helps reduce damage to crops while minimizing the impact on beneficial insects and the environment. Additionally, it is often applied in combination with other pesticides to enhance its efficacy and manage resistance in pest populations.
