Insecticidal composition containing fluensulfone and allyl isothiocyanate

Abstract

The invention discloses an insecticidal composition containing fluensulfone and allyl isothiocyanate, and relates to the field of pesticides. Chloroplatinic acid is added into isopropanol to obtain a catalyst, allyl glycidyl ether and the catalyst are added into a three-necked flask, a toluene solution containing hydrogen silicone oil is dropwise added to obtain an intermediate A, the intermediate A and polyether amine are added into the three-necked flask, ethanol is added as a solvent, a stabilizing aid is obtained; the stabilizing aid is added into the composition, the problems that foams are easily generated in the dilution process of the existing pesticide, the dispersion uniformity of the pesticide is reduced, the pesticide effect is influenced and the spraying operation is interfered are solved; the amino group is introduced, so that the hydrophilicity is increased, and the amino group can be ionized, is positively charged, has a good bubble breaking effect on a negatively charged bubble film, remarkably reduces the surface tension, enables a pesticide to be quickly spread, wet and permeate on the surface of a plant, and enables the pesticide to exert higher efficiency, thereby achieving the purpose of reducing the generation of bubbles.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an insecticidal composition containing fluorine sulfone and allyl isothiocyanate. Background technique [0002] Plant nematode disease is a plant disease caused by the invasion and parasitism of plant parasitic nematodes. The normal growth and development of the damaged plants are affected by the invading nematodes absorbing nutrients in the body. The secretions of the nematodes in the metabolic process will stimulate the cells and tissues of the host plant, resulting in plant deformities , so that the production and quality of agricultural products are reduced. At present, the more serious plant nematode diseases include root-knot nematode disease of peanuts and other crops, soybean cyst nematode disease, wheat grain nematode disease, sweet potato stem nematode disease and rice stem nematode disease, etc. Plant parasitic nematodes are mostly linear, colorless or milky white, without se...
