Problems solved by technology

However, its herbicidal spectrum is narrow, and it is difficult to completely kill broad-leaved weeds in wheat fields
[0006] At present, herbicides in wheat fields 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 wheat fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention belongs to the field of pesticides and discloses a herbicidal composition containing clopyralid and thifensulfuron-methyl and application thereof. The herbicide takes clopyralid and thifensulfuron-methyl as the main active ingredients, wherein the mass ratio of clopyralid to thifensulfuron-methyl is (1-80):(1-70) and clopyralid and thifensulfuron-methyl account for 5-85% of the herbicidal composition by mass. The herbicidal composition has obvious effect on preparing the herbicides for controlling the postemergence weeds in the wheat fields, especially the herbicides for controlling various broadleaf weeds in the wheat fields. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does noharm to the wheat and the aftercrops on the premise of improving the drug effect.

Description

technical field [0001] The invention belongs to the field of pesticides and relates to a herbicidal composition, in particular to a herbicidal composition containing clopyralid and thifensulfuron-methyl and an application thereof. Background technique [0002] Wheat is the main food crop in my country. It is reported that every year wheat in the country suffers from weed damage to varying degrees. If weeding is not done in the field, the yield can be reduced by more than 50%. In order to reduce the economic loss caused by weeds and reduce labor intensity, chemical weeding has gradually been accepted by people because of its convenience, quick effect and long control time. [0003] In recent years, with the increase of herbicide varieties and the widespread promotion of chemical control technology in agricultural production, chemical weeding has been widely used in various stages of wheat growth. Due to the different climate characteristics and planting habits in different r...
