Abstract
A sulfonylurea herbicide for controlling broadleaf weeds, nutgrass flatsedges and Gramineae weeds in paddy rice field is a two- or three-components mixture including metsulfuron-methyl, cinosulfuron and acetochlor, and features obvious synergism, high safety of paddy rice and long effective period.
Description
Herbicidal compositions of the present invention comprises binary or ternary mixture that metsulfuron-methyl, cinosulfuron, Acetochlor etc. are mixed.
The structural formula of cinosulfuron:
The structural formula of metsulfuron-methyl:
The structural formula of Acetochlor:
Cinosulfuron, the activity of weeding height of sulfonylurea herbicides such as metsulfuron-methyl, can effectively prevent and kill off annual and perennial broad leaved weed, sedge weed, inhibitory action to the barnyard grass grass is relatively poor, therefore, preventing and kill off Gramineae ruderal also needs to be mixed with other weed killer herbicide, it is fine that Acetochlor is prevented and kill off the grassy weed effect, and it is cheap, begun in China south rice field in recent years to use, but because active school height, single agent is used and is easily gone out poisoning, in order to solve above-mentioned existing problems, the present invention proposes agricultural cost lower, to rice safety, herbicidal effect is obvious, can prevent and kill off the Herbicidal compositions of the various weeds of paddy rice whole growing.
Drug effect result shows: the yellow grand and Acetochlor complex preparation of ether, can prevent and kill off broad leaved weed, sedge weed in the paddy rice effectively, and obvious synergistic effect is arranged, enlarged kill grass spectrum, lasting period long, to rice safety, can be used as the one-time weeding preparation of paddy rice.
Metsulfuron-methyl is used for agent for removing grass in paddy field, and activity of weeding is yellow grand also higher than ether, and yellow grand being mixed of metsulfuron-methyl and ether reduced the yellow grand consumption of ether, reduced drug cost, has enlarged and has killed the grass spectrum.
Ether is yellow grand, being mixed of metsulfuron-methyl and Acetochlor, and does not have antagonism between each component.
Prove that by field plot trial Herbicidal compositions of the present invention has no adverse effects to ecotope, the operating period is longer.
The auxiliary agent that is adopted in the preparation has: sodium lignin sulfonate, dispersant NNO, dispersing agent CNF, lauryl sodium sulfate, penetrant t, Nekal BX, farming breast 500
#, farming breast 1600
#, farming breast 200
#, farming breast 100
#, CMC, 1656H, 1656L.
Stabilizing agent used in the preparation has: potassium dihydrogen phosphate, boric acid, ammonium chloride, barium sulfate, sodium phosphate trimer etc.
The filler that is adopted in the preparation has: diatomite attapulgite, kaolin bentonite, precipitated calcium carbonate, sodium bicarbonate etc.
Above-mentioned mixture can be made into wetting powder, water dispersion granule, granule, emulsion.
In binary of the present invention or the ternary mixture, the ratio (percentage by weight) that each composition is shared: metsulfuron-methyl 0.1-10%, the yellow grand 0.1-10% of ether, Acetochlor is 4-60%, auxiliary agent 5-10%, stabilizing agent 5-10%, filler is supplemented to 100%.

Herbicidal compositions of the present invention, the result of the test of cutting weeds at paddy field sees Table 1.
Can find out from table 1, Herbicidal compositions of the present invention, the herbicidal effect of preventing and kill off barnyard grass grass, broad leaved weed than application metsulfuron-methyl, the agent of cinosulfuron list obviously increases.
