The original drug was white crystal. The melting point was 19-201 °c. In acetone solubility of lOg/L, soluble in N,N-methyl formamide, pyrrole and other organic solvents, insoluble in water. It is easy to decompose in case of alkali or strong acid, and is stable in storage under normal conditions, and also stable to light and heat.
synthesis from O-chlorobenzoyl chloride and p-chlorophenyl urea in the presence of catalyst. Alternatively, oxalyl chloride (or phosgene) is reacted with O-chlorobenzamide to form o-chlorobenzoyl isocyanate, which is then reacted with P-chloroaniline.
benzoylurea insecticides, inhibit insect chitin synthesis, hinder the larvae peeling, so that the body is not normal and died. To the stomach toxic effect, but also has the effect of killing. It has the advantages of high efficiency and low toxicity, long residual effect and no environmental pollution. It has a good therapeutic effect on wheat armyworm, Dendrolimus punctatus, Brassica rapa, Hyphantria, Mosquito and Fly. Cabbage with 25% suspension 500-1000 times liquid spray, control of citrus leaf moth with 2500-5000 times liquid spray. Should not be used near the mulberry garden.
It has no obvious stimulation effect on rabbit eyes and skin. Teratogenic, carcinogenic and mutagenic effects were not found in animal experiments. There was no cumulative effect in animals. It is safe for fish, birds, natural enemies and bees.
