DIFLUBENZURON is a benzoylphenyl urea used on forest and field crops to selectively control insects and parasites. Principal target insect species are the gypsy moth, forest tent caterpiller, several evergreen eating moths, and the boll weevil. It is also used as a larvae control chemical in mushroom operations and animal houses. Diflubenzuron is a stomach and contact poison. It acts by inhibiting the production of chitin, a compound that makes the outer covering of the insect hard and thus interferes with the formation of the insect’s cuticle or shell.
