Description
Technical field
The present invention relates to composition pesticide technical field, especially a kind of rice herbicide of containing Bispyribac-sodium.
Background technique
Rice herbicide is can to make weeds that withered agriculture agent thoroughly or selectively occur, to eliminate or inhibit weeds raw
A long substance without inhibiting paddy growth.
Currently, the resistant weed in China rice crop field mainly has barnyard grass, Monochoria vaginalis, difformed galingale herb, angustifolia arrowhead herb, duck tongue
Grass, alternanthera philoxeroides (water peanut) etc..The herbicide principal item that paddy field uses has dichloro quinolinic acid, cyhalofop-butyl, five fluorine
Sulphur grass amine, metamifop, butachlor, pretilachlor, bensulfuron-methyl, pyrazosulfuron, Bentazon, 2 first, 4 chlorine and its compound preparation.
The herbicidal performance of above-mentioned herbicide and the popularity of herbicidal spectrum need to be improved
Summary of the invention
In view of the above-mentioned problems existing in the prior art, a kind of the present invention provides drug effects soil that is high, will not influence paddy field
The rice herbicide of the containing Bispyribac-sodium of earth property.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of rice herbicide of containing Bispyribac-sodium, the active constituent of the herbicide is that bispyribac-sodium and methyl iodide sulphur are grand, double
Careless ether and the grand mass ratio of methyl iodide sulphur are as follows: 1-10:2-8.
Further, bispyribac-sodium and the grand mass ratio of methyl iodide sulphur are as follows: 1:2,1:3,1:5,1:8,2:5,2:7.
Further, the dosage form of the herbicide be wettable powder, it is water dispersible granules, aqueous suspension agent, oil-suspending agent, micro-
One of emulsion, suspended emulsion or aqueous emulsion.Wettable powder, water dispersible granules, aqueous suspension agent, oil-suspending agent, microemulsion,
Suspended emulsion or aqueous emulsion are existing known technology, and preferably wettable powder, water dispersible granules, aqueous suspension agent or oil suspend
Agent.Auxiliary material in above-mentioned dosage form be selected from wetting agent, dispersing agent, stabilizer, thickener, antifreezing agent, suspension stabilizer, defoaming agent,
Preservative, disintegrating agent, solvent, filler etc..
Wetting agent is alkyl sulfate, sulfonate, fatty acid or aliphatic ester sulfate, carboxylic acid soaps, phosphate, polyoxy

Preservative is benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, calcium propionate.One of
Disintegrating agent is potato starch, sodium carboxymethyl starch, starch, any one in ammonium sulfate, can accelerate moisture
The disintegration rate of shot agent in water, makes water dispersible granules more rapid and better play a role.
Solvent is methyl oleate, methyl esterification soybean oil, corn oil, any one in white oil, can adsorb and remove well
Effective component in careless agent, reaches slow release effect.
Filler is montmorillonite, talcum powder, white carbon black, silica, any one in precipitated calcium carbonate, can be well
The effective component in herbicide is adsorbed, slow release effect is reached.
Further, the active constituent accounts for the 2%-90% of the total weight of herbicide.
Further, the active constituent accounts for the 10%-60% of the total weight of herbicide.
A kind of rice herbicide of containing Bispyribac-sodium is preventing and kill off the application in paddy field annual grassy weeds.
It is using the beneficial effect of technical solution of the present invention:
In the present invention by after bispyribac-sodium and the grand compounding of methyl iodide sulphur to for examination weeds barnyard grass, Monochoria vaginalis, difformed galingale herb, wild kind
The activity of weeding of aunt is above activity when bispyribac-sodium and grand methyl iodide sulphur is used alone, and has synergistic effect.It is killed after another compounding
Grass spectrum is expanded, and dosage is also reduced.
Using bispyribac-sodium and methyl iodide sulphur is grand compounds in the present invention, the combination of two kinds of effective component expands herbicide
Spectrum, not only sealed but also killed, a drug can be effectively controlled Weed infestation in rice entire breeding time, can make up for it single dose using defect with
Limitation.
