Description
(1) technical field
The present invention relates to technical field of pesticide, particularly one contains the herbicidal composition of 2,4-Dichlorophenoxybutanoic and derivative thereof.
(2) background technology
One of paddy rice Shi Shi world staple food crop, the population of nearly half, is all food with rice, produces throughout each continent except the South Pole in the world.The cereal crops that China paddy rice is also main, China's Monitoring of Paddy Rice Plant Area accounts for 1/4 of plant of grain crops area, area at 3,500 ten thousand hectares, and output account for over half.No matter cultivated area and output, all ranks first in China cereal crops.
Paddy field weed kind is many, and according to statistics, the kind that can form Weed infestation has kind more than 200, wherein, the most generally, harm the most serious kind have kind more than 20.Main weeds have barnyard grass, moleplant seed, lady's-grass, Monochoria korsakowii, duckweed, short arrowhead, angustifolia arrowhead herb, alternanthera philoxeroides, nutgrass flatsedge etc., and the pattern of farming of paddy rice and tillage method also varied, different Weed infestation is had in rice seedling bed, live field, transplant field, also have different weed killer herbicides to select, the difficulty causing agent for removing grass in paddy field is increasing.
Current herbicide for paddy field is mainly divided into herbicide before seedling stage as Acetochlor, butachlor, isopropyl methoxalamine etc.; Herbicide after seedling such as metamifop, cyhalofop-butyl mainly prevent and treat grassy weed; The control such as bensulfuron-methyl, pyrazosulfuron broad leaved weed, the control such as bentazone, azoles humulone nutgrass flatsedge.Along with a large amount of uses of above-mentioned weed killer herbicide, Weed Resistance problem is more and more serious, and mixing disposable solution rice field grass family broad leaved weed by composite or bucket becomes active demand.
2,4-Dichlorophenoxybutanoic and derivative (A) thereof belong to the growth hormone herbicide of phenoxy carboxylic acid, and it effectively can prevent and kill off the annual or perennial broadleaf weed of major part, also can effectively prevent and kill off various nutgrass flatsedge, invalid to grass family.By with following weed killer herbicide (B1-1) alachlor; (B1-2) Acetochlor; (B1-3) the third careless amine; (B1-4) butachlor; (B1-5) isopropyl methoxalamine; (B1-6) propisochlor; (B1-7) mefenacet; (B2-1) cyhalofop-butyl; (B2-2) fenoxapropPethyl; (B2-3) metamifop; (B3-1) pyrazosulfuron; (B3-2) bensulfuron-methyl; (B3-3) metsulfuron-methyl; (B3-4) halosulfuronmethyl; (B4) dichloro quinolinic acid; (B5-1) two careless ether, (B5-2) KIH 6127; (B5-3) pyribenzoxim; (B6) clomazone, (B7) oxaziclomefone, (B8) bentazone, (B9) molinate, (B10-1) Evil humulone, (B10-2) Bing Que Evil humulone, (B11) azoles humulone are mixed expands herbicide spectrum, reduce by 2,4-Dichlorophenoxybutanoic consumption, it is time saving and energy saving to use.2,4-Dichlorophenoxybutanoic and derivative mixture thereof, as the purposes of herbicide for paddy field, there is not yet open.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the complementation of a kind of herbicide spectrum, uses the time saving and energy saving herbicidal composition containing 2,4-Dichlorophenoxybutanoic and derivative thereof.
The present invention is achieved through the following technical solutions:
A kind of herbicidal composition containing 2,4-Dichlorophenoxybutanoic and derivative thereof, it is characterized in that: comprise active component A and active component B that weight proportion is 1-100:100-1, wherein, active component A is 2,4-Dichlorophenoxybutanoic compounds, and its general formula is
or
, in general formula, R is selected from hydrogen or methyl, ethyl, propyl group, butyl, 2-ethylhexyl; M is selected from sodium ion, potassium ion, ammonium ion, dimethyl amine ion, isopropylamine ion; Active component B is one or more weed killer herbicides following: (B1-1) alachlor; (B1-2) Acetochlor; (B1-3) the third careless amine; (B1-4) butachlor; (B1-5) isopropyl methoxalamine; (B1-6) propisochlor; (B1-7) mefenacet; (B2-1) cyhalofop-butyl; (B2-2) fenoxapropPethyl; (B2-3) metamifop; (B3-1) pyrazosulfuron; (B3-2) bensulfuron-methyl; (B3-3) metsulfuron-methyl; (B3-4) halosulfuronmethyl; (B4) dichloro quinolinic acid; (B5-1) two careless ether, (B5-2) KIH 6127; (B5-3) pyribenzoxim; (B6) clomazone, (B7) oxaziclomefone, (B8) bentazone, (B9) molinate, (B10-1) Evil humulone, (B10-2) Bing Que Evil humulone, (B11) azoles humulone.
The present invention conducts in-depth research active component A, it is unexpected that this compounds of discovery not only have high activity of weeding, and to rice safety, to paddy field difficulty control the broad-leaved such as angustifolia arrowhead herb, Monochoria korsakowii, rhizoma alismatis, firefly Lin and nutgrass flatsedge remarkably productive, shortcoming is invalid to grass family.In order to energy disposable solution rice field standing grain basis, broad-leaved and nutgrass flatsedge weeds, composite with existing weed killer herbicide B is a desirable selection, the application through a large amount of screenings and test, find and active component B composite can reduce usage amount, herbicide spectrum complementation, use time saving and energy saving advantage.
More excellent scheme of the present invention is:
The weight proportion of described active component A and active component B is 1-20:20-1.
In general formula, R is selected from hydrogen, butyl, 2-ethylhexyl; M is selected from sodium ion, potassium ion, ammonium ion.
Active component A is known substance, can prepare by the method for bibliographical information.
The present invention has herbicide spectrum widely, can prevent and treat grassy weed, broad leaved weed and nutgrass flatsedge; Can play good synergy, compared with single dose, there is obvious synergistic effect, and herbicide speed is fast, has good safety to paddy rice.
(4) embodiment
Following is a list part the compounds of this invention, in order to the present invention to be described, but do not limit the present invention.
Following table is part the present invention 2,4-Dichlorophenoxybutanoic compounds
.
Following table is the derivative of part the present invention 2,4-Dichlorophenoxybutanoic
.
Due to Late Cambrian of the present invention as active component A demonstrates good safety to paddy rice, therefore can be used as herbicide for paddy field and use.Active component A is particularly suitable for the sedge weed such as the broad leaved weed such as Monochoria korsakowii, alternanthera philoxeroides, rhizoma alismatis, angustifolia arrowhead herb, short arrowhead, firefly Lin, difformed galingale herb preventing and treating the more difficult control of other existing weed killer herbicides.Active component B is one or more following weed killer herbicides, can remove all weeds of disposable solution by wealthy pair of standing grain, and to rice safety.
