Abstract
The invention discloses a herbicidal composition containing fluazifop-p-butyl and clethodim and application thereof. The herbicidal composition takes fluazifop-p-butyl and clethodim as the main active ingredients, wherein the mass ratio of fluazifop-p-butyl to clethodim is (1-70):(1-80) and fluazifop-p-butyl and clethodim account for 5-85% of the herbicidal composition by mass. The herbicidal composition has obvious effect on preparing the herbicides for controlling the postemergence weeds in the soybean fields, especially the herbicides for controlling various grass weeds in the soybean fields. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the rapes and the aftercrops on the premise of improving the drug effect.
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 clethodim clethodim.
Technical background
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.
Its structural formula is as follows:
Be mainly used in preventing and treating annual and perennial grassy weeds such as 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, with low dose, under drought condition, use high dose.And its herbicidal effect influences seriously by weather and rainwater, therefore, is subjected to the influence that local climate changes in the use.
Clethodim has another name called and receives happy leading to.Chemical name: (±)-2-[(E)-3-chloroallyloxyamino imino group] propyl group-5-[2-(ethylmercapto group) propyl group]-3-hydroxyl hexamethylene-2-ketenes.Belong to the cyclohexenone analog weed killer herbicide.Structural formula is:
This weed killer herbicide is inner sucting conduction type cauline leaf inorganic agent, and good selectivity is arranged, and grassy weed is had very strong lethal effect, to dicotyledonous crops safety.Cauline leaf is handled and is absorbed rapidly by leaf, be transmitted to meristematic tissue, in sensitive plant, suppress the biosynthesis of branched chain fatty acid and flavonoids and work, its cell division is destroyed, suppress the merismatic activity of plant, plant strain growth delayed, after the dispenser in 1-3 week plant move back green necrosis, it is withered and dead to burn with posterior lobe, effective to most of annual and perennial grassy weeds.In the resistance plant body, can degrade rapidly, form the polarity product, and loss of activity rapidly, to dicotyledon, the nutgrass flatsedge activity is very little or non-activity.But it is invalid to broad leaved weed, because clethodim is used in the soybean field for a long time, some weeds have produced serious resistance to it.
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 clethodim.
Another object of the present invention provides this weed killer herbicide and prevents and kill off application in the weed killer herbicide of soybean weeds in preparation.
A kind of Herbicidal combinations that contains efficient fluazifop and clethodim is characterized in that this Herbicidal combinations is main active ingredient with efficient fluazifop and clethodim, and the mass ratio of efficient fluazifop and clethodim is 1～70: 1～80.The mass ratio of preferred efficient fluazifop and clethodim is 1～50: 1～60.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of efficient fluazifop and clethodim 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 clethodim, except active ingredients such as efficient fluazifop and clethodim, 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 clethodim is the weed killer herbicide of preventing and kill off grassy weed.Both can improve the control to multiple annual gramineous weed and perennial grassy weed after mixing.
3, delay the weeds resistance.Weed killer herbicide of the present invention reduces weeds to the resistance of 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.
Safe.Herbicidal combinations of the present invention is applied to soybean field postemergence weed control, and it can prevent and kill off the various grassy weeds of soybean Tanaka, under the prerequisite that has improved drug effect, soybean and succession crop is all had very high safety.
