Long life cycle, high efficiency and low toxicity, uneasy to produce drug resistance
The Company's pesticide products such as cartap, monosultap and bisultap are highly effective broad spectrum insecticides, which are bionical pesticides of the nereistoxion type, and are excellent varieties to replace high-toxic pesticides. Due to the uneasily generated drug resistance and the long life cycle, demand in foreign markets is strong. Phosphorous acid, as a chemical product, is mainly used as a reducing agent; nylon brightener is also used as the raw material for phosphite, pesticide intermediate and the raw material for organophosphorus water treatment agent.
Cartap
It is an insecticide of nereistoxin series, molecular formula: C7H16CLN3O2S2, white powder, soluble in water; slightly soluble in methanol, insoluble in ethanol, insoluble in acetone, chloroform, benzene and other organic solvents. Slightly hygroscopic. It is stable under normal temperature and acidic conditions, but unstable under alkaline conditions. No carcinogenic, teratogenic, or mutagenic effects, toxic to silkworms, low toxic to birds, and safe to natural enemies such as spiders.
It can be absorbed and conducted by the leaves and roots of crops, with stomach action, contact killing and inner-absorption conducting and ovicidal action. It knocks down pests quickly, with a long residual life, and a broad spectrum of pests. It has a good control effect on the rice stem borers. The Company registers and produces 98% TC and 90% SP
Monosultap
An insecticide of nereistoxin series, molecular formula: C5H14NO7S4Na, white to light yellow powdered solid, soluble in water, slightly soluble in methanol, ethanol, dimethylformamide, and dimethyl sulfoxide, and insoluble In carbon tetrachloride, benzene, and ethyl acetate.
It is stable in acidic and neutral solutions, and is easily decomposed in alkaline solutions. It has stomach toxicity, contact killing and inner-absorption conducting effects, with a certain fumigation effect. It is used to control rice leafhoppers, plant hoppers, parnara guttatas, phyllotreta vittutas, cabbage caterpillars, sehizaphis piricolas, etc. The Company registers and produces 95% TC and 90% SP.
Bisultap
An insecticide of nereistoxin series, molecular formula: C5H11NO6S4Na2, soluble in water, stable in acidic and neutral solutions, and easily decomposed in alkaline solutions.
The medicine is a competitive inhibitor of acetylcholine, which acts on the ganglion cholinergic synapse, and inhibits the synaptic transmission of the insect central nervous system, thus causing the death of insects. It has strong contact killing, gastric toxicity, fumigation and inner-absorption conducting effects. This product has a good prevention effect on yellow stem borers. The Company registers and produces 29% AS and 18% AS.
Phosphorous acid
Molecular formula: H3PO3, white crystals, with strong hygroscopicity and deliquescent, soluble in water and alcohol, with strong reducing, slowly oxidized to phosphoric acid in the air.
It is used for synthetic fiber and phosphite,and can also be used as a raw material of stabilizers for plastics.
