Abstract

The invention discloses a pymetrozine oil suspending agent and a preparation method thereof. The pymetrozine oil suspending agent comprises the following components in mass: 3-60% of pymetrozine, 2-25% of emulsifying agent, 0.1-10% of thickening agent, 0-5% of PH adjusting agent and a solvent to 100%. The pymetrozine oil suspending agent has stable physical and chemical properties and is difficult to decompose and deteriorate; and the adsorption and the osmosis of the drug to a target are enhanced, and the effective utilization rate of the drug is increased.

Description

technical field [0001] The invention belongs to the field of pesticide formulations, and in particular relates to a pymetrozine oil suspension and a preparation method. Background technique [0002] Pymetrozine belongs to pyridine or triazinone insecticides. It is a brand-new non-biocide insecticide. It was first developed by Ciba-Geigy in Switzerland in 1988. Pests showed excellent control effect. Studies using electropenetrography (EPG) techniques have shown that no matter in drip, feeding or injection experiments, as long as aphids or planthoppers are exposed to pymetrozine, they almost immediately produce a stylet blocking effect, stop feeding immediately, and eventually starve. fatal, and the process is irreversible. Therefore, pymetrozine has an excellent function of blocking insect transmission. Although the mechanism of the stylet blockage caused by pymetrozine is not yet clear, existing studies have shown that this irreversible "stop eating" is not caused by "ant...
