The present invention relates to the Herbicidal combinations containing promazine Sulfometuron Methyl and pyribenzoxim and bentazone, and active ingredient is promazine Sulfometuron Methyl, pyribenzoxim, bentazone；Weight percent of the promazine Sulfometuron Methyl in Herbicidal combinations is 0.1%~30%, and weight percent of the pyribenzoxim in Herbicidal combinations is 0.1%~40%, and weight percent of the bentazone in Herbicidal combinations is 0.1%~40%.Herbicidal combinations of the present invention have synergistic function, prevent and kill off that rice terrace annual grassy weeds is with obvious effects to be used alone better than each single dose, and expand herbicide controlling spectrum, while reduce dosage, have delayed the generation of herbicide resistance, have alleviated pollution to environment.
Description
Technical field
The invention belongs to technical field of pesticide, and in particular to one kind is with promazine Sulfometuron Methyl and pyribenzoxim and bentazone
For the Herbicidal combinations of the synergistic response of active ingredient, suitable for preventing and kill off rice terrace annual grassy weeds.
Background technology
Promazine Sulfometuron Methyl (propyrisulfuron) is a kind of selective broad-spectrum herbicide, to resistance to sulfonylurea herbicide
Weeds have preferable preventive effect, it is effective to above the average age for marriage barnyard grass, nutgrass flatsedge, broadleaved herb, can foliar spray, get rid of and apply.
Pyribenzoxim (pyribenzoxim) is that pyridine salicylic acid class herbicide is inhibitor of acetolactate synthetase, quilt
It is changed into active acid after plant absorption and plays herbicide effect, be rice field broad-spectrum herbicide, can effectively prevents and kill off barnyard grass (including to enemy
The barnyard grass of barnyard grass, dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), annual sedge weed, it is and miscellaneous to numerous broad-leaveds
It is careless effective, such as the different stamen flower of natural pond life, carp intestines, sesbania, ring flower, Monochoria vaginalis.
Bentazone (bentazone) is a kind of selective killing type herbicide after seedling, at weeds seedling stage cauline leaf
Reason.Be mainly used for the crops such as rice, soybean, peanut, wheat, prevent and kill off broad leaved weed and sedge weed, to grassy weed without
Effect.
The present inventor has made intensive studies promazine Sulfometuron Methyl, pyribenzoxim, bentazone mixture, finds the phonetic sulphur of promazine
Grand, pyribenzoxim, bentazone mixture have synergistic response, especially to moleplant seed (Leptochloa chinensis),
Barnyard grass (Echinochloa crusgalli), green bristlegrass (Setaria viridis), bent grass (Agrostis
Matsumurae), Paspalum distichum (Paspalum paspaloides), Yunnan ditch millet (Paspalum delavayi), hair flower sparrow
Barnyard grass (Paspalum dilatatum), Leersia Sw (Leersia hexandra), the nit careless (Leptochloa panicea), duck
Tongue grass (Monochoria vaginalis), triquetrousc murdannia herb (Murdannia triquetra), rhizoma alismatis (Alisma plantago-
Aquatica), arrowhead (Sagittaria trifolia var.sinensis), firefly Lin (Scirpus juncoides), Scirpus tabernaemontani
(Scirpus validus), difformed galingale herb (Cyperus difformis), summer dichotomous fimbristylis herb (Fimbristylis
Aestivalis (Retz.) Vahl) there is apparent synergistic response.
Promazine Sulfometuron Methyl, pyribenzoxim, the compounding of bentazone are without relevant report.
The content of the invention
It is an object of the invention to solve the problems, such as in the prior art to develop immunity to drugs to farmland weed and actual control effect
It is poor, provide it is a kind of efficiently, low toxicity, quick-acting is good and the lasting period is long, be conducive to the Herbicidal combinations of farmland weed comprehensive treatment.
It is another object of the present invention to which the Herbicidal combinations are prevented and kill off farmland weed, particularly for preventing and kill off rice terrace one
