Embodiment 1

[0036] Embodiment 1 prepares the emulsifiable concentrate preparation that active ingredient content is 20%

[0037] Weigh foramsulfuron-methyl and atrazine and dissolve in xylene and dimethylformamide, then add emulsifier Nongru 2201 and stir evenly to obtain the emulsifiable concentrate.

[0038] The specific ratio is:

[0039] Raw material dosage (parts by weight)

[0040] Foramsulfuron 0.5

[0041] Atrazine 19.5

[0042] Farm Milk 2201 10

[0043] Xylene 50

[0044] Dimethylformamide 20

Embodiment 2

[0045] Embodiment 2 prepares the emulsifiable concentrate preparation that active ingredient content is 30%

[0046] The active ingredients nicosulfuron and atrazine were weighed and dissolved in xylene and methylformamide, and then the emulsifier Nongru 2201 was added and stirred evenly to obtain the emulsifiable concentrate.

[0047] The specific ratio is:

[0048] Raw material dosage (parts by weight)

[0049] Nicosulfuron 1

[0050] Atrazine 29

[0051] Farm Milk 2201 10

[0052] Xylene 40

[0053] Dimethylformamide 20

Embodiment 3

[0054] Embodiment 3 prepares the emulsifiable concentrate preparation that active ingredient content is 50%

[0055] The active ingredients foramsulfuron-methyl and cyanazine were weighed and dissolved in xylene and methylformamide, and then the emulsifier Nongru 2201 was added and stirred evenly to obtain the emulsifiable concentrate.

[0056] The specific ratio is:

[0057] Raw material dosage (parts by weight)

[0058] Foramsulfuron 2

[0059] Cyanazine 48

[0060] Farm Milk 2201 10

[0061] Xylene 20

[0062] Dimethylformamide 20

Abstract

The present invention provides a weedicide composition. It is characterized by that it contains sulfonylurea weedicide and s-tripyridine weedicide as active component.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a herbicide composition. Background technique [0002] Due to competing with crops for glory and water and fertilizer, farmland weeds cause great losses to crop production every year. At present, the main method for preventing and controlling weeds in farmland is to spray pesticides. [0003] Atrazine belongs to the triazine herbicides, the English common name is Atrazine, the chemical name is 2-chloro-4-ethylamino-6-isopropylamino-1,3,5,-triazine, is a A selective soil treatment and foliar herbicide that kills plants by inhibiting their photosynthesis. The disadvantage is that the range of weeding is narrow, it is not easy to decompose, and it is easy to cause phytotoxicity to the next crop after use. [0004] Foramsulfuron belongs to the sulfonylurea herbicides, the English common name is Foramsulfuron, the chemical name is 1-(4,6-dimethoxypyrimidin-2-yl)-3-(2-dimethylaminocarbonyl...
