Abstract

The invention relates to an insecticidal composition of pyrifluquinazon and cyenopyrafen, wherein the weight ratio of two active ingredients is 1: 30-30: 1; the total mass percentage content of the active ingredients in the insecticidal composition is 4-80%; and the rest are auxiliary ingredients which are allowed to be used and acceptable in pesticides, and the composition can be prepared into asuspending agent, an aqueous emulsion, a microemulsion, missible oil, a wettable powder agent, a microcapsule suspending agent, a water dispersible granule, a soluble powder agent and a soluble granule. The composition has obvious synergistic crops, can reduce the utilization rate of pesticides, and is environment-friendly and safe.

Description

technical field [0001] The invention relates to the field of pesticide compositions, in particular to a pesticide and insecticidal composition containing fifluraquine and pyrazafen. Background technique [0002] Pyrifluquinazon, chemical name: (1-acetyl-1,2,3,4-tetrahydro-3-[(3-pyridylmethyl)amino]-6-[1,2, 2,2,-Tetrafluoro-1-(trifluoromethyl)ethyl]quinazolin-2-one, fifluraquine, is known and described, for example, in EP1097932; its molecular formula is: [0003] . [0004] Fluramid, developed by Nippon Pesticides, is a new quinazoline insecticide. Fluramiquin is generally used in water-dispersible granules in actual production. Its mechanism of action is to stop pests from feeding and starve to death, thereby preventing more damage to plant tissues and controlling the spread of some important diseases. At present, it is mainly used to control whiteflies, aphids and scale insects on vegetables, fruit trees and tea leaves. [0005] Cyenopyrafen (common name in English: ...
