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.
Quick Detail:
Product name: Diflubenzuron 25%WP
Pesticide category: Insecticide
CAS NO.: 35367-38-5

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.
