Abstract
The invention discloses a herbicidal composition containing fluazifop-p-butyl and acifluorfen sodium and application thereof. The herbicidal composition comprises the fluazifop-p-butyl and the acifluorfen sodium which serve as the main active ingredients, wherein the mass ratio of the fluazifop-p-butyl to the acifluorfen sodium is 1-70:1-80; and the fluazifop-p-butyl and the acifluorfen sodium account for 5 to 85 percent of the total mass of the herbicidal composition. The herbicidal composition can be used for controlling post-emergence weeds in soybean fields, and particularly has obvious effect when used for preparing herbicides for controlling various gramineous weeds and broadleaf weeds in the soybean fields. Compared with single-composition herbicide, the herbicide composition postpones the resistance of the weeds, has a broad weeding spectrum and acts for a long time on the premise of improving the herbicide effect and is safe for rape and afterculture crops.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of Herbicidal combinations, be specifically related to a kind of Herbicidal combinations and application thereof that contains efficient fluazifop and acifluorfen.
Background technology
Efficient fluazifop has another name called fluazifop-p-butyl, chemical name: (R)-and the 2-{4-[(5-trifluoromethyl)-2-base-pyridine radicals] the oxygen base } butyl propionate.Belonging to phenoxy carboxylic acid herbicides, is the fatty acid synthetic inhibitor, is fluorinated heterocycle highy potent herbicide of new generation.Be mainly used in annual and perennial grassy weeds such as control barnyard grass grass, wild oat, green foxtail, golden green foxtail, eleusine indica, amur foxtail, moleplant seed, india lovegrass, bromegrass, Hordeum, Secale, millet genus, annual bluegrass, Bermuda grass, Paspalum distichum, false Chinese sorghum, reed, wild silkworm, cogongrass, quackgrass.Full field dispenser or seedling band application medicine all can.The little usefulness of weeds leaf age is hanged down dose, and leaf age is big uses high dose; Under the good situation of moisture condition,, under drought condition, use high dose with low dose.Invalid to broadleaved herb and nutgrass flatsedge, and its herbicidal effect influences seriously by weather and rainwater, therefore, be subjected to the influence that local climate changes in the use, and the part weeds is serious to its resistance.
Acifluorfen has another name called weeds and burns.Chemical name: 5-[2-chloro-4-(trifluoromethyl)-phenoxy group]-2-nitrobenzoic acid (sodium), this weed killer herbicide is a kind of tagging property weed killer herbicide.Early time treatment behind the seedling, absorbed by weeds, the mode of action is for tagging, can impel stomatal closure, by means of light performance activity of weeding, increase the plant corpus temperature and cause necrosis, and suppress the conduction of mitochondria electronics, to cause the stagnation of respiratory system and energy production system, suppress cell division weeds are caused death.But enter in the soybean body,, therefore can selectivity prevent and kill off broad leaved weed by metabolism rapidly.In normal soil, can not penetrate into dark soil layer, can be degraded into carbonic acid gas by microorganism in the soil and daylight.But acifluorfen is bad to the preventive effect of 3 grassy weeds of leaf more than the phase, and, soybean there is certain poisoning, using dosage is required relatively stricter.
Soybean field herbicide is limit by crop safety at present, it is also limited to kill the grass spectrum, be used alone the agent of weed killer herbicide list and can not control the generation of soybean weeds completely effectively, moreover some weed killer herbicide is because water-soluble big or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all causes easily this season crop or succession crop of dispenser.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains efficient fluazifop and acifluorfen.
Another object of the present invention provides this Herbicidal combinations and prevents and kill off application in the soybean weeds weed killer herbicide in preparation.
A kind of Herbicidal combinations that contains efficient fluazifop and acifluorfen, it is characterized in that this Herbicidal combinations is main active ingredient with efficient fluazifop and acifluorfen, the mass ratio of efficient fluazifop and acifluorfen is 1～70: 1～80, and the mass ratio of preferred efficient fluazifop and acifluorfen is 1～50: 1～60.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of efficient fluazifop and acifluorfen is 5～85%, and the preferred mass percentage composition is 10～75%.
In the binary built preparation of efficient fluazifop of the present invention and acifluorfen, except active ingredients such as efficient fluazifop and acifluorfen, can also add the auxiliary agents such as conventional surfactants, thickener, solvent or solid packing that allow on the pesticidal preparations and be mixed with any one formulation that allows on the agricultural chemicals.Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wetting powder etc.
Herbicidal combinations provided by the invention can be applicable to prepare the weed killer herbicide of preventing and kill off soybean Tian Miaohou weeds, particularly prevents and kill off to use in the weed killer herbicides of the various grassy weeds of soybean Tanaka in preparation to have remarkable result.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding height.Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism, makes weeds resistance generation speed reduce, and greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Efficient fluazifop is the broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and acifluorfen is a weed killer herbicide of preventing and kill off grass family and broad leaved weed.Both can improve the control to multiple grassy weed and broad leaved weed after mixing.
3, delay the weeds resistance.Weed killer herbicide of the present invention reduces the resistance of weeds to medicament by binary built, and improves the preventive effect of antagonism weeds, thereby prolongs the service life of medicament.
4, safe.Because its using dosage is under control, make medicament under the prerequisite that has improved drug effect, its safety to field, field such as soybean, cotton, rape and tobacco and succession crop also is improved.
