Abstract

The invention provides a weeding composition for monocotyledon crops and application thereof. The weeding composition contains a component A and a component B serving as active components, wherein the component A is an effective detoxification quantity of 2,2-dimethyl-N-[(4-methyl phenyl) sulfonyl]-5-(methyl)-3-oxazolidine formamide, the component B is one of chlorsulfuron, chlorimuron-ethyl, imazethapyr or fomesafen. The weight ratio of effective volume of the component A to effective volume of the component B is (1-8):2. The dosage form is wettable powder, missible oil, a suspending agent, water dispersed granules or a seed coating agent. The weeding composition is applied to monocotyledon crop fields, and compared with mono-agents, the efficacy is improved, a weeding spectrum is also expanded, and the herbicide resistance of weeds can be further delayed. The weeding composition is safe to current-reap crops and after-reap crops, does not bring secondary herbicide damage and can effectively prevent and control the damage brought by herbicides. The performance of the weeding composition can obviously exceed the conventional technological level.

Description

technical field [0001] The present invention relates to a herbicidal composition for monocot crops and its use. Background technique [0002] A large number of herbicides provide a strong guarantee for the modernization of agriculture, effectively suppress the harm of weeds, significantly increase the grain output of farmland, and bring huge economic benefits to the world's agricultural industry. However, herbicides have encountered some difficulties in the application process, the most prominent ones are the residual phytotoxicity and the resistance of weeds. Some herbicides also have a strong killing function on crops, and the application of pesticides during the growth period of crops is likely to cause phytotoxicity to crops. The residues of some herbicides during use can inhibit the growth of the following crops and cause secondary phytotoxicity. Some pesticides can also cause phytotoxicity to crops at normal use concentrations, which can affect yields in mild cases, ...
