Problems solved by technology

[0006] Imperata praecox, red thistle, iron mango, goosegrass, and small fly canopy are common weeds in various crop fields, forest land, and non-cultivated land. Using glufosinate-ammonium, glyphosate, or mefentrazone alone cannot effectively To control these weeds, the best control effect can only be increased
However, achieving the control effect by increasing the dosage will inevitably increase the herbicide resid

Embodiment 1

[0031] Embodiment 1 (32% glufosinate-ammonium · glyphosate · fentrazone wettable powder):

[0032] By weight percentage, glufosinate-ammonium 1.9%, glyphosate sodium salt (calculated as glyphosate) 30%, fenflumezone 0.1%, calcium lauryl sulfate 5%, sodium lignosulfonate 5%, Sodium methylene bis-naphthalene sulfonate is 8%, and the balance is light calcium carbonate.

[0033] According to the conventional pesticide preparation processing technology, according to the above formula, glufosinate-ammonium, glyphosate, fenflutrazone, calcium lauryl sulfate, sodium lignin sulfonate, sodium methylene bis-naphthalene sulfonate, and light calcium carbonate were sequentially Add it into a mixer and mix thoroughly, and the uniformly mixed material is added into a jet mill and pulverized until the fineness reaches 325 mesh, and a wettable powder of the composition with an active ingredient content of 32% is obtained.

Embodiment 2

[0034] Embodiment 2 (65% glufosinate-ammonium · glyphosate · fentrazone wettable powder):

[0035] By weight percentage, glufosinate-ammonium 15%, glyphosate sodium salt (calculated as glyphosate) 40%, fenflumezone 10%, sodium lauryl sulfate 5%, calcium lignosulfonate 3%, Sodium butylnaphthalene sulfonate 2%, balance is light calcium carbonate.

[0036] Add glufosinate-ammonium, glyphosate, fenflutrazone, sodium lauryl sulfate, sodium lignin sulfonate, sodium butylnaphthalene sulfonate, and light calcium carbonate into the mixer in sequence according to the above formula, and mix thoroughly. The homogenized material was put into a jet mill and pulverized until the fineness reached 325 mesh, and a composition wettable powder with an active ingredient content of 65% was obtained.

Embodiment 3

[0037] Example 3 (65.4% glufosinate-ammonium glyphosate-metaflutrazone wettable powder):

[0038] By weight percentage, glufosinate-ammonium 20.2%, glyphosate potassium salt (calculated as glyphosate) 35%, fenflumezone 10.2%, sodium lauryl sulfate 2%, sodium lignosulfonate 3%, Sodium lauryl ether sulfate 1%, the balance is kaolin.

[0039] According to the conventional pesticide preparation processing technology, according to the above formula, glufosinate-ammonium, glyphosate, fenflutrazone, sodium lauryl sulfate, sodium lignosulfonate, sodium lauryl ether sulfate, and kaolin were sequentially added into the mixer to fully Mixing, the homogeneously mixed material is put into a jet mill and pulverized until the fineness reaches 325 mesh, and a composition wettable powder with an active ingredient content of 65.4% is obtained.

Abstract

The invention discloses a herbicide composition containing glufosinate ammonium, glyphosate and carfentrazone-ethyl. The herbicide composition is characterized in that the pesticide active ingredients of the composition are glufosinate ammonium, glyphosate or salts thereof and carfentrazone-ethyl; based on the herbicide composition, the weight percent of the pesticide active ingredients is 31.1-85%, wherein the weight percent of the glufosinate ammonium is 1-30%, the weight percent of the glyphosate or salts thereof is 30-70%, the weight percent of the carfentrazone-ethyl is 0.1-20%, and the balance is non-pesticide ingredients. The dosage forms of the herbicide composition are wettable powder, water dispersible granules, soluble powder, soluble granules, aqueous solutions, emulsion in water and microemulsion. The herbicide composition has the advantages that after compounding, the herbicide composition has obvious synergistic effects, expands the weed control spectrum, increases the weed control speed, obviously reduces the usage amount and numbers of use of herbicides and can be applied to controlling imperata cylindrica, ageratum conyzoides, dicranopteris dichotoma, eleusine indica, erigeron canadensis and other weeds in arable lands and non-arable lands.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and in particular relates to a herbicide composition, especially a herbicide composition with glufosinate-ammonium, glyphosate or a salt thereof and fenclozone as active ingredients. The herbicide composition It can be used to control weeds such as Imperata cylindrica, Ageratum conyzoides, Dicranopteris dichotoma, Eleusine indica, Erigeron canadensis and other weeds. technical background [0002] Glufosinate-ammonium is also known as glufosinate, Baoshida, English common name glufosinate ammonium, CA registration number: 77182-82-2, chemical name; (RS)-2-amino-4-(hydroxymethoxyl)butyl ammonium acid. Molecular formula C 5 h 15 N 2 o 4 P, molecular weight 198.16. It is a phosphonic acid herbicide, a glutamine synthesis inhibitor, and a non-selective contact herbicide with partial systemic action. After application, the ammonium metabolism in the plant can be disturbed within ...
