Dicyclanil is primarily used as a growth regulator in agriculture, specifically for the control of insect pests in rice crops. It disrupts the normal development of insects by interfering with their metamorphosis, effectively preventing larvae from developing into adults. This makes it highly effective against rice plant hoppers, a major pest in rice farming. Its unique mode of action reduces the likelihood of cross-resistance with other insecticides, making it a valuable tool in integrated pest management programs. Dicyclanil is applied as a foliar spray or soil treatment and offers long-lasting protection due to its systemic properties, being absorbed and distributed within the plant. It is especially useful in early crop growth stages, providing protection during critical periods of plant development.
