Problems solved by technology

Weeds are generally controlled with glyphosate, but glyphosate still cannot be used to eradicate the malignant weed rice Lishihe (a perennial grass weed), and its damage is getting worse year by year. Excavation is labor-intensive and incomplete
In addition, glyphosate is completely ineffective against another vicious weed, the water bamboo leaves (commelinaceae), and the damage is serious. In serious cases, the grass must be cut off before mechanical farming

Embodiment 1

[0011] Embodiment 1 The herbicide of the present invention is mixed by glyphosate (glyhosate), fenoxaprop-p-ethyl (fenoxaprop-p-ethyl) and bensulfuron-methyl (bensulfuron-methyl) three kinds of original drugs, wherein each original drug The weight contents are respectively: 80% of glyphosate, 8% of fenoxaprop-ethyl, and 12% of bensulfuron-methyl. During application, every 25 grams of the herbicide of the present invention adds 12.5 liters of dilutions, and is used for removing the weeds such as rice Lishihe and water bamboo leaves in the paddy field.

Embodiment 2

[0012] Embodiment 2 The herbicide of the present invention is mixed by glyphosate, quizalofop-p-ethyl (quizalofop-p-ethyl) and cinosulfuron (cinosulfuron) three kinds of former medicines, wherein the weight content of each former medicine is respectively: glyphosate Phosphine 90%, quizalofop-ethyl 4%, etesulfuron-methyl 6%.

Embodiment 3

[0013] Embodiment 3 The herbicide of the present invention is mixed by glyphosate, refined haloxyfop-p-methyl (haloxyfop-p-methyl) and three kinds of original medicines of ethoxysulfuron (ethoxysulfuron), wherein the weight content of each original medicine is respectively : 80% glyphosate, 7% hachlorpyr-ethyl, 13% ethoxysulfuron-methyl.

Abstract

The invention discloses a herbicide composed by mixing glyphosate, aryloxy-phenoxy-propionic acid herbicidal substances and sulfonylurea herbicidal substances, the weight content being 65-90% of glyphosate, 3-15% of aryloxy-phenoxy-propionic acid herbicidal substances and 5-20% of sulfonylurea herbicidal substances. The herbicide of the invention has perfect eradication effect to various worst weeds, is particularly suitable for controlling the two worst weeds such as Leersia oryzoides and triquetrousc murdannia herb, and is widely used for rice field, ridge, abandoned fields, mulberry garden and tree parks.

Description

technical field [0001] The present invention relates to a herbicide and its use. Background technique [0002] After the beginning of spring, the weeds in the paddy fields grow one after another. Weeds are generally controlled with glyphosate, but glyphosate still cannot be used to eradicate the malignant weed rice Lishihe (a perennial grass weed), and its damage is getting worse year by year. Excavation is labor-intensive and incomplete. In addition, glyphosate is completely ineffective against another vicious weed, the water bamboo leaves (commelinaceae), and the damage is serious. In severe cases, the grass must be cut off before mechanical farming. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a herbicide capable of effectively removing weeds in paddy paddy fields, especially rice prunus and water bamboo leaves, and its application. [0004] In order to solve the above-mentioned technical problems, a kin...
