Abstract
The invention discloses a kind of Herbicidal composition for rice field, active ingredient is bensulfuron-methyl, penoxsuam, cyhalofop-butyl.Bensulfuron-methyl percentage by weight is in the composition 1% ~ 10%, and penoxsuam percentage by weight is in the composition 1% ~ 10%, cyhalofop-butyl percentage by weight is in the composition 1% ~ 15%, and all the other are insecticides adjuvant.The invention has the advantages that the composite rear raising herbicidal effect of bensulfuron-methyl, penoxsuam, cyhalofop-butyl, expand herbicide spectrum, low toxicity, low-residual, and significantly reduce dosage, times for spraying and use cost, composition effect, apparently higher than each single dose, is the good new compositions medicament of current water prevention rice field annual weed.
Description
Technical field
The present invention relates to a kind of Herbicidal composition for rice field, is with bensulfuron-methyl, penoxsuam and cyhalofop-butyl for active ingredient, for water prevention rice field annual weed.
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds.In recent years, because some weed killer herbicide kind large area are used alone, a lot of weeds have been caused to develop immunity to drugs.Meanwhile, grass when weeds occur is mutually complicated, and grassy weed, broad leaved weed, the mixed life of nutgrass flatsedge multiclass weeds, single variety weed killer herbicide uses can not solve farmland weed, all can show defect in a certain respect and limitation.Variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.
Bensulfuron-methyl, English name: bensulfuron-methyl, chemical name: α-{ [(4,6-dimethoxypyridin-α-Ji) amino carbonyl amino] sulfonvlmethvl } methyl benzoate, structural formula:
Bensulfuron-methyl is selectivity inner-adsorption conduction-type herbicide, can spread rapidly in water, transfers to each portion of weeds, the biosynthesis of hindered aminoacid, lysine, isoleucine, stop division and the growth of cell for weeds root and blade absorb.Susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the growth of leaf portion, hinders root growth and downright bad.Entering rapid metabolization in paddy rice body is harmless inert chemi-cal thing, to rice safety.Bensulfuron-methyl not only to the broad leaved weeds such as Monochoria vaginalis, special-shaped nutgrass flatsedge, duckweed, alternanthera philoxeroides, nutgrass flatsedge effectively, also has activity to barnyard grass.
Cyhalofop-butyl, English name: cyhalofop-butyl, chemical name: (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate, structural formula:
Cyhalofop-butyl is kind paddy rice in fragrant phenoxy phenoxy propionic acid weed killer herbicide to tight security.Cyhalofop-butyl is also Uptake and translocation weed killer herbicide, by blade and the leaf sheath absorption of plant corpus, phloem conducts, accumulate the meristem zone in plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized and stops, the growth division of cell can not normally be carried out, membranous system etc., containing fat structural deterioration, finally cause Plant death.Cyhalofop-butyl, not only to moleplant seed, also can prevent and treat the grassy weeds such as barnyard grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail.
Penoxsuam, English name: penoxsulam, chemical name: 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) triazole-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN), structural formula:
Penoxsuam is inner-adsorption conduction-type herbicide, through cauline leaf, young shoot and Root Absorption, and can by soil rapid adsorption, conduct to meristematic tissue by xylem and phloem, suppress plant strain growth, make growing point chlorosis, after process, 7-14d terminal bud reddens, downright bad, and 2-4 week plant is dead; This agent is strong inhibitor of acetolactate synthetase, and medicament presents comparatively slow, needs certain hour weeds just dead gradually.Rice field broad-spectrum herbicide, effectively can prevent and kill off barnyard grass and annual sedge weed, and have numerous broad leaved weed, also anti-bensulfuron-methyl weeds in rice field can be prevented and kill off, and to many broad-leaveds and sedge weed and barnyard grass etc., there is residual activity, be the kind that herbicide spectrum in current herbicide for rice field is the widest.
Variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.Being screened by formulation of pesticide, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay disease, worm, the drug-fast generation of crop smothering, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to bensulfuron-methyl, penoxsuam and cyhalofop-butyl conducts in-depth research, find that bensulfuron-methyl, penoxsuam and cyhalofop-butyl carry out mixture, synergy or summation action is had to paddy field annual weed in certain mixed ratio scope, after further study, the present invention is completed.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention is used for preventing and kill off paddy field annual weed etc. by this Herbicidal combinations.
Technical scheme: for achieving the above object, the invention provides a kind of Herbicidal composition for rice field, and active ingredient is bensulfuron-methyl, penoxsuam, cyhalofop-butyl.Bensulfuron-methyl percentage by weight is in the composition 1% ~ 10%, and penoxsuam percentage by weight is in the composition 1% ~ 10%, cyhalofop-butyl percentage by weight is in the composition 1% ~ 15%, and all the other are insecticides adjuvant.
