Herbicidal mixture composition before seedling stage in soybean field

Abstract

The invention relates to an herbicidal composition, and particularly relates to an herbicidal mixture composition before a seedling stage in a soybean field. The composition is prepared from the following raw materials in parts by weight: 52-60 parts of a thifensulfuron extractive, 28-35 parts of metolachlor, 28-35 parts of propisochlor, 13-22 parts of alachlor, and 10-15 parts of s-metolachlor. The herbicidal composition disclosed by the invention adopts different acting modes for weeding, regards different tissue parts of weeds as absorption paths and uses a synthetic action mode including contact-killing, uptake and translocation to respectively act on different target enzymes of the weeds so as to get rid of the weeds for one time, efficiently avoids succession of weed communities and enhancement of herbicide resistance, can reduce environment pollution and threat to crops and food safety, and achieves obvious effects on field thistle, endive and duck madder.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a soybean field pre-emergence herbicide mixture composition. 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 hi...

Problems solved by technology

[0005] Moreover, in the current production, due to the relatively single herbicide species applied in the soybean field before emergence and the influence of climatic factors, the weeding effect is often unsatisfactory.
