Problems solved by technology

[0011] However, clopyralid is ineffective against gramineous weeds, and the herbicidal spectrum is not wide enough, so its use is limited
[0012] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also li

Abstract

The invention discloses a herbicidal composition containing nicosulfuron and clopyralid, and application thereof. The herbicidal composition takes the nicosulfuron and the clopyralid as active ingredients; and the mass ratio of the nicosulfuron to the clopyralid is (1-70) to (1-80). Compared with a single-component herbicide, the herbicidal composition delays weed resistance, has a broad herbicidal spectrum and acts for a long time on the premise of enhancing herbicide effect, and is safe for corns and afterculture crops. The herbicidal composition can be used for preparing herbicide for controlling and killing weeds of the grass family and broad leaves in the corn fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound composition of clopyralid and nicosulfuron and an application thereof. The herbicidal composition can be applied to post-emergence weeding in corn fields. Background technique [0002] Corn is the main food crop in my country, with a planting area of ​​20 million ha. Left and right, divided into spring sowing and summer sowing, the three northeastern provinces and Xinjiang mainly produce spring corn, and the Huanghuaihai region mainly produces summer corn. It is reported that about 1 / 2 area of ​​corn in the country is affected by weeds in different degrees, and the area of ​​severe weeds is about 10-20%. If weeding is not done in the field, the corn 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 been gradually accepted ...
