Problems solved by technology

However, with the extensive use of bensulfuron-methyl, many weeds have gradually developed resistance to it, seriously affecting the use of bensulfuron-methyl
[0010] 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 discloses a synergistic herbicidal composition containing clopyralid and bensulfuron-methyl and application thereof. The main active ingredients of the herbicidal composition are the clopyralid and the bensulfuron-methyl in a mass ratio of 1-70:1-60. The synergistic herbicidal composition can be used for controlling post-emergence weeds in a wheat field, and particularly has an obvious effect of controlling various broadleaf weeds in the wheat field. Compared with a single-component herbicide, the herbicidal composition delays resistance of weeds, has broad herbicidal spectrum and acts for a long time on the premise of improving herbicide effect, and is safe for wheat and afterculture crops.

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 of clopyralid and bensulfuron-methyl. The herbicide composition can be applied to stem and leaf weeding in wheat fields. Background technique [0002] Wheat is the main food crop in my country. It is reported that wheat in the whole country suffers from weed damage in different degrees every year. If weeding is not done in the field, it can reduce its yield 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 cl...
