Abstract
The invention belongs to the field of weeding, and discloses a mixing weed killer containing bentazone, acifluorfen-sodium and fluazifop-p-butyl, and an application thereof. The mixing weed killer adopts the bentazone, the acifluorfen-sodium and the fluazifop-p-butyl as main effective components, wherein a mass ratio of the bentazone to the acifluorfen-sodium to the fluazifop-p-butyl is 0.1-80:0.1-80:0.1-80, the total mass percentage of the three materials in the mixing weed killer is 1-85%. The mixing weed killer provided by the present invention can be applicable for weeding in the soybean field after seedling, specifically provides significant effects for prevention and elimination of various grassy weeds and broadleaf weeds in the soybean field. Compared to the single weed killer, in the premise of improvement of the efficacy, the weeding composition provided by the present invention delays the resistance generating of the weeds, and has wide weeding spectrum and long effective duration, and provides safeties for the soybean and the succeeding crops.
Description
Technical field
The invention belongs to the weed killer herbicide field, relate to a kind of mixed herbicide and application thereof that contains bentazone, acifluorfen and fluazifop-p-butyl.
Technical background
Bentazone has another name called Lysimachia sikokiana pellet, Bentazon, chemical name: the 3-isopropyl-(1H)-and benzo-2,1,3-thiadiazine-4-ketone-2, the 2-dioxide, structural formula is:
This weed killer herbicide is an optionally herbicide after seedling of contact killing type tool, is used for cauline leaf processing in seedling stage, works by the blade contact.When in dry land, using, be transmitted to by the blade face infiltration earlier and suppress photosynthesis in the chloroplast.Can absorb by root again by the blade face infiltration when in the paddy field, using, be transmitted to cauline leaf, hinder weeds photosynthesis and water metabolism strongly, cause nutrition hunger, make physiological function lack of proper care and cause death.Bentazone active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, to crop safety, and 6-18 week after the dispenser, can be in soil by microbial decomposition.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Fluazifop-p-butyl has another name called efficient fluazifop, 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 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.Efficient fluazifop is 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 (acifluorfen-sodium), other titles: weeds are burnt, Da Keer, chemical name: 5-[2-chloro-4-(trifluoromethyl)-phenoxy group)-and 2-nitrobenzoic acid sodium, be a kind of diphenyl ether herbicide.Its structural formula is:
Acifluorfen is a kind of tagging property weed killer herbicide, early time treatment behind the seedling, can be absorbed by weeds stem, leaf, the mode of action can be impelled stomatal closure for tagging, by means of light performance activity of weeding, increase the plant corpus temperature and cause necrosis, and the transmission of inhibition mitochondria electronics, to cause the stagnation of respiratory system and energy production system, suppress cell division and make weeds death.This weed killer herbicide can be prevented and treated annual broadleaf weeds such as soybean Tanaka's black nightshade, knotweed, acalypha copperleaf, Amaranthus retroflexus, dayflower, artemisiifolia, piemarker, lamb's-quarters, Siberian cocklebur, beggar-ticks, and perennial corn sow thistle, field thistle, setose thistle, meadow pine etc. are had stronger inhibitory action.But acifluorfen is invalid to grassy weed and nutgrass flatsedge, and soybean has the property of tagging poisoning, therefore, wants strict control consumption in the use, or with other herbicide mixtures, reduce poisoning and improve preventive effect grassy weed.
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 mixed herbicide that contains bentazone, acifluorfen and fluazifop-p-butyl.
Another object of the present invention provides this herbicide applications.
A kind of mixed herbicide that contains bentazone, acifluorfen and fluazifop-p-butyl, it is characterized in that this weed killer herbicide is main active ingredient with bentazone, acifluorfen and fluazifop-p-butyl, the mass ratio of bentazone, acifluorfen and fluazifop-p-butyl is 0.1～80: 0.1～80: 0.1～80, and the mass ratio of preferred bentazone, acifluorfen and fluazifop-p-butyl is 1～60: 1～50: 1～40.
In mixed herbicide, bentazone, acifluorfen and the fluazifop-p-butyl three gross mass percentage composition in weed killer herbicide is 1～85%, and preferred gross mass percentage composition is 20～75%.
In the ternary built preparation of bentazone of the present invention, acifluorfen and fluazifop-p-butyl, except active ingredient bentazone, acifluorfen and fluazifop-p-butyl, 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 aqueous emulsions such as suspending agent, missible oil, water dispersion granule, wetting powder.
Mixed herbicide of the present invention can be used in the weed killer herbicide of preparation soybean field postemergence weed control, particularly uses in preventing and kill off various grass family of soybean Tanaka or broad leaved weed.
Herbicidal composition of the present invention has the following advantages:
1, activity of weeding height.Herbicidal composition of the present invention can kill weeds by three kinds of different mechanism, makes weeds resistance generation speed reduce, and has greatly improved the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Three kinds of weed killer herbicides to kill the grass spectrum different, the three is combined the herbicidal spectrum and the activity of these three kinds of medicaments with the be mixed medicament that makes of special ratios, make that the herbicidal spectrum of mix preparation is wideer, the lasting period is longer.
3, delay the weeds resistance.The present invention can significantly improve the preventive effect to various resistant weeds, delays the drug-fast generation of weeds, prolongs the service life of medicament.
4, safe.Herbicidal composition of the present invention is applied to soybean field postemergence weed control, and it can prevent and kill off various grass family of soybean Tanaka or broad leaved weed, under the prerequisite that has improved drug effect, soybean and succession crop is all had safety.
