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 limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

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, especially the field of herbicides, and relates to a binary compound composition of clopyralid and nicosulfuron and its application. The herbicidal composition can be used for post-emergence weeding in corn fields. Background technique [0002] Corn is my country's main food crop, with a national planting area of ​​20 million hectares. It is divided into spring sowing and summer sowing. Spring corn is mainly used in the three northeastern provinces and Xinjiang, and summer corn is mainly used in the Huang-Huai-Hai region. It is reported that about 1 / 2 of the country's corn area is affected by varying degrees of weed damage, and about 10-20% of the area with severe weed damage. If weeding is not carried out in the field, the corn yield can be reduced by more than 50%. In order to reduce the economic losses caused by weed damage and reduce labor intensity, and also because of its convenience, ...
