Abstract

The invention belongs to the technical field of pesticide compound, particularly relates to a monosultap contained EW (emulsion in water) and application. Effective ingredients of the composition are bifenthrin and monosultap, wherein the weight ratio of monosultap to bifenthrin is (1:1) to (1:10). The compound combination effectively resists the problem about production of pest resistance, thereby mitigating the conventional resistance to drugs of pests to the largest extent; less use of pesticide reduces influence on the environment, and the trend of environmental protection in future society is conformed; the composition provided by the invention achieves the optimal crop protection effect.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an aqueous emulsion containing monosultap and its application. Background technique [0002] Insecticide list [0003] Product Category: Insecticides [0004] English name: Monosultap [0005] CAS No. 29547-00-0 [0006] Molecular formula C 5 H 12 NNaO 6 S 4 [0007] Molecular weight: 333.4 [0008] Physical and chemical properties Appearance: white to light yellow powdery solid, melting point: 142-143°C, no visible foreign impurities. [0009] Solubility: easily soluble in water, easily soluble in industrial ethanol; slightly soluble in methanol and other organic solvents. Under the condition of strong acid and strong alkali, it can be hydrolyzed into nereistoxin. [0010] Monosultap is a synthetic analogue of nereistoxin, which is rapidly converted into nereistin or dihydronereistin in insects. The drug is a competitive inh...
