Abstract

The invention belongs to the technical field of pesticides, and discloses an herbicidal composition, which uses oxaziclomefone, penoxsulam, and clomazone as main active ingredients, wherein the mass ratio of oxaziclomefone to penoxsulam to clomazone is (0.1 to 20) to (0.1 to 15) to (0.1 to 50), and the sum of the three is 1 to 80% by mass in the herbicidal composition. The invention also discloses a water dispersible granule, a wettable powder, a suspending agent, an emulsifiable concentrate and a granule prepared by the herbicidal composition, has the advantages of high efficiency, low toxicity, low cost, quick effect and long duration, and can be used for controlling annual grass weeds, broadleaf weeds and cyperaceae weeds of a rice paddy field.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicidal composition, in particular to a herbicidal composition containing oxazicone, penoxsulam and clomazone and an application thereof. Background technique [0002] Rice is the main food crop in my country, accounting for 40% of food production. Rice is a short-day crop that likes temperature and humidity. The country is divided into double-cropping rice, single-cropping rice, and single- and double-cropping rice. It is reported that about 1 / 2 of the country's rice area is affected by weeds to varying degrees, and the area of ​​severe weeding is about 10-20%. If weeding is not done in the field, the rice yield can be reduced by more than 50%. In order to reduce the economic loss caused by weed damage and reduce labor intensity, chemical weeding has gradually become the first choice of farmers because of its convenience, quick effect and long control time. [0003] In re...
