Overview[1]
Although many insecticides and acaricides have been developed to control various pests (such as agricultural and horticultural pests or pests harmful to health) and have been used individually or in mixtures in practice, the results of repeated use of these agents Yes, pests have developed resistance to various pesticides. In particular, economically important insects in agriculture and horticulture, such as spider mites that are susceptible to insecticide resistance due to their ability to lay large numbers of eggs and produce large numbers of offspring, can develop resistance in just a few days. is attracting a lot of attention. Para-chlorophenyl-chlorobenzene sulfonate is a relatively effective and anti-drug-resistant acaricide.
Purpose[2]
P-chlorophenyl p-chlorobenzene sulfonate can be used as acaricide, and the pure product is colorless crystal. The industrial product is white or brown solid. Insoluble in water, soluble in a variety of organic solvents. It will definitely become sexual and have a fishy smell. p-Chlorophenyl p-chlorobenzene sulfonate is chemically stable and can be decomposed when exposed to alkaline substances. The dosage forms are emulsifiable concentrate, wettable powder and powder. It can control the larvae and eggs of various red spider mites on a variety of crops. Low toxicity to humans and animals. Rat oral administration LD502000mg/kg. The acceptable daily intake of p-chlorophenyl p-chlorobenzene sulfonate is 0.01mg/kg (body weight). Japan’s pesticide registration retention standard stipulates 0.8 mg/kg for fruits and 0.5 mg/kg for vegetables. .
