The invention discloses an insecticidal composition containing cyprosulfuron and application of the insecticidal composition. The effective components of the insecticidal composition are composed of cyprosulfuron and
pyrethroid, wherein the
pyrethroid is perfluthrin, dimefluthrin, trifluthrin, dextro-trans-
propargyl chloride pyrethrin, perfluthrin, dextro-phenothrin, dextro-
tefluthrin, chlorenthrin, beta-
cypermethrin, meperfluthrin,
bifenthrin,
deltamethrin, cis-
cypermethrin and beta-
cyhalothrin, and the
pyrethroid is a mixture of dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin, dimefluthrin and dimefluthrin. Any one of beta-
cyfluthrin and beta-
cyfluthrin; the total weight of the cyprosulfuron and the pyrethroid accounts for 2.2%-40% of the insecticidal composition, and the weight ratio of the cyprosulfuron to the pyrethroid is (10: 1)-(1: 2). The
pesticide has the characteristics of high efficiency,
low toxicity and the like, is used for space spraying or retention spraying, is quick in effect, thorough in killing and long in lasting period, reduces the
pesticide application amount, and reduces the
pesticide application
irritation. The composition can be widely applied to hotels, schools, factories, farms, families and public places, and has a special effect on preventing and treating sanitary pests.
