Abstract

The invention relates to a pymetrozine micron emulsion and a preparation method thereof. The pymetrozine micron emulsion includes the components by weight: 1-20% of pymetrozine, 5-40% of a solvent, 6-20% of an emulsifier, 1-5% of a penetrant, 1-5% of a synergist and the balance water. The invention discloses a preparation method of the pymetrozine micron emulsion. The pymetrozine micron emulsion can be used for the insect control of agriculture field nuisanceless production. The pymetrozine micron emulsion is stable in performance, high in insecticidal activity, and improved in efficacy, and reduces the dosage of medicament.

Description

Technical field [0001] The invention is a pesticide field, which involves a pyrine micro -emulsion and its preparation methods. Background technique [0002] Pyrephinone is a pyridine pesticide with high efficiency, low toxic, low residue, long -lasting period, and strong internal absorption. It is a new non -killer pesticide.Pests show an excellent prevention and treatment effect.Research using electrical penetrating graphs (EPG) technology shows that whether it is a bit, feeding or injection test, as long as aphids or livelings are exposed to pyrine, a degenerative obstruction effect is almost immediately generated, and the feeding is immediately stopped and eventually hungryDeath, and this process is irreversible. [0003] At present, the use of pyromone is mainly wettable powder. It produces a large amount of dust during the production of wettable powder, polluting the air, and use of dust pollution.Therefore, the development of new liquid preparations to reduce or eliminate ...
