Problems solved by technology

[0004] 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...

Abstract

The invention discloses a weeding composition containing metazosulfuron and bentazone. The weeding composition adopts the metazosulfuron and bentazone as main effective components, and a mass ratio ofthe metazosulfuron to the bentazone is 1:50 to 59:1. The invention also discloses an application of the weeding composition in wheat field weeding. The weeding composition can be used in wheat fieldweeding, and especially has a significant prevention and control effect on sedge broad leaf weeds in the wheat field. Compared with single doses, the weeding composition has the advantages of drug effect improvement, weed resistance delaying, broad weeding spectrum, long persistent period, and safety to wheat and later crops.
