New Function and Preparation of Diflubenzuron

Diflubenzuron is a white to yellowish crystalline solid with a melting point of 210-230°C (decomposition) and a vapor pressure of <0.013 millipascals. It is insoluble in water but slightly soluble in most organic solvents. As a urea insecticide, it exhibits stomach poison and contact killing effects without systemic activity. Its aqueous solution is effective against various leaf-eating larvae and concealed

Can diflubenzuron be compounded with those pesticides?

Diflubenzuron, a new insecticide, exhibits stomach poison effects on the larvae of many important pests. It interferes with cuticle deposition, preventing insects from undergoing normal molting or metamorphosis, leading to their death. It can also inhibit the formation of the cuticle during embryo development inside insect eggs, resulting in abnormal development and hatching. Additionally, it has a certain inhibitory effect
