35367-38-5 Diflubenzuron Insecticide / Wood Borer Insecticide for Tree , Plant

Description:

Diflubenzuron is a benzamide insecticide used on forest and field crops to selectively

control insects and parasites. Principle target insect species are the gypsy moth, forest

tent caterpiller, several evergreen eating moths and the boll weevil. Diflubenzuron is a

stomach and contact poison which acts by inhibiting the production of chitin (a compound

that makes the outer covering of the insect hard) and so interferes with the formation of

the insect's cuticle or shell. It is also used as a larvae control chemical in mushroom

operations and animal houses.

Diflubenzuron is classified as a Restricted Use Pesticide (RUP) in the United States.

Restricted Use Pesticides may be purchased and used only by certified applicators.

Applications:

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). Formulation types GR; HN; OF; SC; UL; WG; WP.
