Chitin synthesis inhibitor; and so interferes with the formation of the insect cuticle. This action is quite specific; related biochemical
processes, such as chitin synthesis in fungi, and biosynthesis of hyaluronic acid and other mucopolysaccharides in chickens, mice and rats
are not affected.

For control of a wide range of leaf-eating insects in forestry, woody ornamentals and fruit. Controls certain major pests in cotton,
soya beans, citrus, tea, vegetables and mushrooms. Also controls larvae of flies, mosquitoes, grasshoppers and migratory locusts.
Used as an ectoparasiticide on sheep for control of lice, fleas and blowfly larvae. Due to its selectivity and rapid degradation in soil
and water, diflubenzuron has no or only a slight effect on the natural enemies of various harmful insect species. These properties
make it suitable for inclusion in integrated control programmes. Diflubenzuron is effective at 25-75 g/ha against most leaf-feeding
insects in forestry; in concentrations of 0.01-0.015% a.i. against codling moth, leaf miners and other leaf-eating insects in top fruit; in concentrations of 0.0075-0.0125% a.i. against citrus rust mite in citrus; and at a dosage of 50-150 g/ha against a number of pests in
cotton (cotton boll weevil, armyworms, leafworms), soya beans (soya bean looper complex) and maize (armyworms). Also for control
of larvae of mushroom flies in mushroom casing (1 g/m2); mosquito larvae (25-100 g/ha); fly larvae in animal housings (0.5-1 g/m2
surface); and locusts and grasshoppers (60-67.5 g/ha).
