Embodiment 1

[0038] Example 1: 53% rimsulfuron-oxazone-oxoctyl fluroxypyr wettable powder.

[0039] The herbicide composition raw material consumption of the present embodiment is:

[0040] Flumesulfuron-methyl 8kg, fenflurzone 5kg, fluroxypyr isooctyl 40kg, sodium lauryl ether sulfate 2kg, calcium lignosulfonate 8kg, sodium methylene bis-naphthalene sulfonate 7kg, bentonite 20kg, white Carbon black 10kg.

[0041] The preparation method of the herbicide composition of the present embodiment is:

[0042] Add the above materials together into the conical mixer and mix them evenly, then crush them through the jet mill, and then mix the pulverized materials through the conical mixer. powder.

Embodiment 2

[0043] Example 2: 75% rimsulfuron-oxatrazone-isooctyl fluroxyl acetate water-dispersible granules.

[0044] The herbicide composition raw material consumption of the present embodiment is:

[0045] Flumesulfuron 15kg, fenflurzone 10kg, fluroxypyr isooctyl 50kg, sodium alkylbenzene sulfonate 6kg, soluble starch 4kg, ammonium sulfate 5kg, diatomaceous earth 10kg.

[0046] The preparation method of the herbicide composition of the present embodiment is:

[0047] Add the above materials together into the conical mixer and mix them evenly, and then crush them through the airflow mill. The pulverized materials are then mixed through the conical mixer. Knead into a plastic material, and finally put the material into an extruding granulator to extrude and granulate. After granulation, it is dried and sieved to obtain a water-dispersible granule.

Embodiment 3

[0048] Example 3: 40% rimsulfuron-oxatrazone-fluroxypyr-isooctyl oil suspension concentrate.

[0049] The herbicide composition raw material consumption of the present embodiment is:

[0050] Flumesulfuron 25kg, fenflurzone 3kg, fluroxypyr isooctyl 12kg, fatty acid polyoxyethylene ester phosphate 8kg, polyoxyethylene ether sulfonate sodium 10kg, phenylethyl alcohol oleate 3kg, triethanolamine 2kg , organic bentonite 5kg, methyl oleate 22kg, epoxy soybean oil 10kg.

[0051] The preparation method of the herbicide composition of the present embodiment is:

[0052] Put the above materials into the reaction kettle mixer together, stir for 2 hours, then inject the materials into the sand mill for grinding, the fineness of the ground materials is 98% and pass through a 5um sieve before discharging, and the materials are then put into the high-speed shearing machine , After shearing, the oil suspension can be prepared.

Abstract

The invention discloses an herbicide composition. The herbicide composition contains the following active components in parts by weight: 2-50 parts of orthosulfamuron, 1-50 parts of topramezone and 2-70 parts of fluroxypyr-mepthyl. The herbicide composition can be prepared into wettable powder, a water dispersible granule, missible oil, a microemulsion, a suspension agent or a dispersible suspending agent and is used for preventing and killing annual grassy weeds, cyperus weeds and broad leaf weeds in corn fields and sugarcane fields. The herbicide composition is safe to corns and sugarcanes,the use dose of a herbicide in a unit area can be reduced, weeding effect can be improved, and the pharmacy cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide composition and its preparation method and application. Background technique [0002] The control of agricultural weeds has always been the most concerned and important issue in agricultural production. Crops are infested by a variety of weeds for almost the entire growing season. The main weeds in cornfields and sugarcane fields are iron wire grass, barnyardgrass, goosegrass, old crabgrass, Cyperus cyperi, small fly, purslane, solanum nigrum, clover needle grass, pig's weed, cocklebur , Big foxtail, etc. The herbicides currently registered for use in corn fields mainly include mesotrione, nicosulfuron, rimsulfuron, acetochlor, sodium 2-methyl-4-chloride, atrazine, simazine, fluroxypyr One or several active ingredients such as octyl esters are formulated. The herbicides used in sugarcane fields are mainly formulated from one or several active ingredients such a...
