Embodiment 1

[0022] Embodiment 1: the herbicidal composition is a suspension concentrate, and the percentages of each component are respectively:

[0023]

[0024]

[0025] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A, B and C, grind in a ball mill for 2-3 hours, so that the particle diameter is below 5mm, The suspension formulation of the herbicidal composition of the present invention can be prepared.

Embodiment 2

[0026] Embodiment 2: the herbicidal composition is a wettable powder, and the percentages of each component are respectively:

[0027]

[0028] The specific operation steps are: mix the active ingredients A, B and C with other adjuvants and fillers, fully stir in a stirring tank, pulverize through a jet mill and mix evenly to obtain the wettable powder preparation of the herbicidal composition of the present invention .

Embodiment 3

[0029] Embodiment 3: the herbicidal composition is a water-dispersible granule, and the percentages of each component are respectively:

[0030]

[0031] The specific operation steps are: mix the active ingredients A, B and C with other additives and fillers evenly, pulverize them with an ultra-fine jet mill, and add them to a fluidized bed granulation dryer after kneading for granulation, drying, and screening After that, a water-dispersible granule formulation of the herbicidal composition of the present invention can be prepared.

[0032] In the above dosage form, the auxiliary agent is selected from the following:

[0033] The solvent can be trimethylbenzene, tetramethylbenzene, methylnaphthalene, methyl oleate, fatty acid methyl ester, pine oil, soybean oil, biodiesel, sec-butyl acetate, dimethyl carbonate, diesel oil, white oil, motor oil, etc. one or more of them.

[0034] The emulsifier can be calcium dodecylbenzenesulfonate, fatty alcohol polyoxyethylene ether, t...

Abstract

The invention discloses a corn field weed control composition which comprises active ingredients A, B and C, wherein the active ingredient A is tembotrions; the active ingredient B is atrazine; and the active ingredient C can be metolachlor, s-metolachlor or isoxaflutole; the ratio of the active ingredient A to the active ingredient B to the active ingredient C in parts by weight is (1-5) to (1-15) to (1-10); and the total mass of the active ingredient A, the active ingredient B and the active ingredient C is 3%-85% of the mass of a pesticide composition. The weed control composition disclosed by the invention can be prepared into one of a suspending agent, an oil suspension agent, wettable powder or a water dispersible granule according to the application requirements, and is used for preventing and removing annual weeds of a corn field; the effect of the composition for preventing and removing the annual weeds of the corn field is obviously superior to that of a single dosage; the medicine dose is reduced; and the weed resistance is delayed.

Description

technical field [0001] The invention relates to a ternary mixed herbicide composition for controlling annual weeds in cornfields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, a variety of weeds are mixed, and the use of a single herbicide can not solve the weeds in the farmland, which will show some defects and limitations. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, and saving time and labor. [0003] Tetrasulfone, English common name: tembotrione, chemical name: 2-(2-chloro-4-methanesulfonyl-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl) ring Hexane-1,3 dione. Tetratrione belongs to triketone herbicides. After sensitive weeds absorb this...
