Abstract
The invention discloses a herbicidal composition containing fluazifop-p-butyl and bentazone and application thereof. The fluazifop-p-butyl and the bentazone serve as main active ingredients of the herbicidal composition, the mass ratio of the fluazifop-p-butyl to the bentazone is 1-65:1-75, and the fluazifop-p-butyl and the bentazone account for 10 to 85 percent of the total mass of the herbicidal composition. The herbicidal composition is used for controlling postemergence weeds in a rape field, and particularly has an obvious effect of controlling various grass and broadleaf weeds in the rape field. Compared with single-component herbicide, the herbicidal composition delays the weed resistance, has broad herbicidal 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 bentazone.
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.
Bentazone has another name called Lysimachia sikokiana pellet, Bentazon.Chemical name: the 3-isopropyl-(1H)-and benzo-2,1,3-thiadiazine-4-ketone-2,2-dioxide, this weed killer herbicide are optionally herbicide after seedling of contact killing type tool, are used for cauline leaf processing in seedling stage, work by the blade contact.Dry land is used, and is transmitted to by the blade face infiltration earlier and suppresses photosynthesis in the chloroplast.The paddy field is used and can be absorbed by root again by the blade face infiltration, is transmitted to cauline leaf, hinders weeds photosynthesis and water metabolism strongly, causes nutrition hunger, makes physiological function lack of proper care and cause death.Active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, and to crop safety, 6-18 week bentazone can be by microbial decomposition in soil after the dispenser.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Herbicide used in rape field 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 rape field weed 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 bentazone.
Another object of the present invention provides the application of this Herbicidal combinations in the weed killer herbicide of preparation rape field weed.
A kind of Herbicidal combinations that contains efficient fluazifop and bentazone is characterized in that this Herbicidal combinations is main active ingredient with efficient fluazifop and bentazone, and the mass ratio of efficient fluazifop and bentazone is 1～65: 1～75.The mass ratio of preferred efficient fluazifop and bentazone is 1～50: 1～60.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of efficient fluazifop and bentazone is 10～85%, and the preferred mass percentage composition is 10～75%.
In the binary built preparation of efficient fluazifop of the present invention and bentazone, except active ingredients such as efficient fluazifop and bentazone, 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 of the present invention can be applicable to prepare in the weed killer herbicide of preventing and kill off rape Tian Miaohou weeds, particularly prevents and kill off to use in the weed killer herbicide of various grass family of rape Tanaka and broad leaved weed 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 bentazone is a weed killer herbicide of preventing and kill off 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, and makes medicament under the prerequisite that has improved drug effect, its safety to rape and succession crop also is improved.
