Soybean field post-emergence herbicide mixture

Abstract

The invention relates to a herbicide composition, and in particular relates to a soybean field post-emergence herbicide mixture. The composition is prepared from the following raw materials in parts by weight: 30-45 parts of clomazone, 25-35 parts of flumetsulam and 35-40 parts of s-metolachlor. The herbicide composition disclosed by the invention performs weed killing by adopting different action modes, adopts different tissue parts of weeds as absorption routes, respectively acts on different target enzymes of the weeds by virtue of comprehensive action modes of touch killing and intake and transportation, can remove the weeds for one time, can effectively avoid the succession of weed communities and the enhancement of medicament resistance, can be used for reducing the environmental pollution and the threats to crop and food safety, and has significant effects on difficultly-treated weeds such as common dayflower herb, cephalanoplos segetum, cephalanoplos setosum, bottle brush herb, field sowthistle herb and the like.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a soybean field post-emergence herbicide mixture. Background technique [0002] Soybeans (scientific name: Glycine max) are also known as green kernel black beans, soybeans, mud beans, horse feed beans, and fodder beans. There are varieties, winter beans, autumn beans, and green beans. my country is mainly produced in the Northeast. Chinese ancient name Shu, is a crop whose seeds are rich in protein. The leguminous soybeans are oval and spherical in shape, and the colors are yellow, light green, black and so on. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Okara, or soybeans ground into a meal, are also commonly used in livestock feed. [0003] Annual herb, 30-80 cm high. Stems stout, erect, or nearly coiled at the upper part, more or less ribbed at the upper part, densely covered with brown long hirsute. Lea...

Problems solved by technology

[0005] Moreover, in current production, due to the relatively single variety of herbicides used in soybean fields after emergence and the greater impact of climatic factors, the weeding effect is often unsatisfactory.
