Embodiment approach

[0033] As a particularly preferred embodiment of the present invention, the herbicidal composition is preferably in the form of a suspoemulsion formulation, and the herbicidal composition contains flutrachlor and pretilachlor, relative to 1 part by weight of flutrachlor , the content of pretilachlor is 10-30; the herbicide composition also contains polyvinylpyrrolidone, sodium lignosulfonate, styrylphenol polyoxyethylene ether phosphate, fatty alcohol polyoxyethylene ether, xanthan Glue, methyl oleate and water; the total weight of propargylflufen and pretilachlor with water, polyvinylpyrrolidone, sodium lignosulfonate, styrylphenol polyoxyethylene ether phosphate, aliphatic alcohol polyoxygen The ratio of vinyl ether, xanthan gum and methyl oleate is 1: (0.2-1.5): (0.02-0.15): (0.02-0.2): (0.04-0.35): (0.05-0.5): (0.02-0.2 ): (0.06-0.5). In the case of this preferred embodiment, the herbicide composition is especially suitable for controlling weeds in paddy fields, and has a...

Embodiment 1

[0043] In this example, a herbicide composition in the form of suspoemulsion was prepared.

[0044] Get 2 weight parts of propargyl fluoride, 40 weight parts of pretilachlor, 3 weight parts of polyvinylpyrrolidone, 2 weight parts of sodium lignosulfonate, 4 weight parts of styrylphenol polyoxyethylene ether phosphoric acid Esters, 7 parts by weight of fatty alcohol polyoxyethylene ether, 2 parts by weight of xanthan gum, 10 parts by weight of methyl oleate and 30 parts by weight of water were uniformly mixed to obtain the herbicide composition of the present embodiment.

Embodiment 2

[0046] In this example, a herbicide composition in the form of suspoemulsion was prepared.

[0047] Get 3.8 parts by weight of fluorine fluoride propargyl, 38.2 parts by weight of pretilachlor, 3 parts by weight of polyvinylpyrrolidone, 2 parts by weight of sodium lignosulfonate, 4 parts by weight of styrylphenol polyoxyethylene ether phosphoric acid Esters, 7 parts by weight of fatty alcohol polyoxyethylene ether, 2 parts by weight of xanthan gum, 10 parts by weight of methyl oleate and 30 parts by weight of water were uniformly mixed to obtain the herbicide composition of the present embodiment.

Abstract

The invention discloses a herbicide composition, and the herbicide composition contains 1 parts by weight of flumioxazin and 0.15-500 parts by weight of pretilachlor. . The invention also provides the use of the herbicide composition in the prevention and control of weeds in rice lands. Through the technical proposal, the herbicide composition, compared with flumioxazin and pretilachlor, can obtain the obviously enhanced prevention and control effect so as to improve the prevention and control effect of herbicides.

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a herbicide composition and the use of the herbicide composition. Background technique [0002] Rice is one of the main grain crops in my country, accounting for about 29% of the planting area of ​​grain crops. [0003] According to statistics, the area of ​​weed-damaged rice accounts for more than 46% of the total planting area, so weeds compete with rice for water and fertilizer, which is one of the main factors affecting rice yield. If it is not controlled, it will cause a large reduction in yield. [0004] The weeds in the paddy fields are mainly divided into three categories: Gramineae weeds: barnyardgrass, paspalum bispacia; broad-leaved weeds: Arthia chinensis, Yujiuhua, eye vegetable, Alisma, wolfberry, and lotus ; Cyperaceae weeds: special-shaped sedge, flat-stalked sedge, Japanese sedge, firefly (small water onion), and goosegrass; in addition, there are underwater w...
