Problems solved by technology

However, many weeds have developed resistance to it at present, which has caused great restrictions on its sales and use
[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 chlortoluron and application thereof. The nicosulfuron and the chlortoluron serve as main active ingredients; and the mass ratio of the nicosulfuron to the chlortoluron is 1-60:1-80. 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 improving a herbicide effect, is safe for corns and succeeding crops and can be used for preparing herbicides for controlling postemergence weeds in 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 nicosulfuron and chlorotoluron and its application. 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 by people ...
