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 Jing oxazoles
Herbicidal combinations of the diclofop-methyl for 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.
It is inhibitor of acetolactate synthetase that pyribenzoxim (pyribenzoxim), which is pyridine salicylic acid class herbicide, 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.
Fenoxaprop (fenoxaprop-P-ethyl) belongs to heterocyclic oxy group phenoxy propionic acid class herbicide, mainly
By one acetyl-CoA carboxylase of key enzyme that aliphatic acid is inhibited to synthesize, so as to inhibit the synthesis of aliphatic acid, medicament passes through stem
Leaf Assimilation and conductivity is to separate living tissue and the growing point of root, and effect is rapid, stops growing within 2-3 days after dispenser, and lobus cardiacus chlorosis becomes within 5-6 days
Purple, separate living tissue become brown, and blade is gradually withered, are the extremely strong cauline leaf process agent of selectivity.
The present inventor deeply grinds promazine Sulfometuron Methyl and pyribenzoxim and fenoxaprop recipe determination
Study carefully, it is found that three's mixture has synergistic response.
The present inventor has made intensive studies promazine Sulfometuron Methyl, pyribenzoxim, fenoxaprop mixtures, finds third
Piperazine Sulfometuron Methyl, pyribenzoxim, fenoxaprop mixtures have synergistic response, especially to moleplant seed (Leptochloa
Chinensis), barnyard grass (Echinochloa crusgalli), bent grass (Agrostis matsumurae), Paspalum distichum
(Paspalum paspaloides), Yunnan ditch millet (Paspalum delavayi), hairy flowered paspalum (Paspalum
Dilatatum), Leersia Sw (Leersia hexandra), the nit careless (Leptochloa panicea), triquetrousc murdannia herb
(Murdannia triquetra), rhizoma alismatis (Alisma plantago-aquatica), arrowhead (Sagittaria trifolia
Var.sinensis), firefly Lin (Scirpus juncoides), Scirpus tabernaemontani (Scirpus validus), summer dichotomous fimbristylis herb
(Fimbristylis aestivalis (Retz.) Vahl) has apparent synergistic response.
Promazine Sulfometuron Methyl, pyribenzoxim, fenoxaprops compounding without relevant report.
