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: 3-isopropyl-(1H)-benzo-2,1, and 3-thiadiazine-4-ketone-2, the 2-dioxide, structural formula is:
This weed killer herbicide is optionally herbicide after seedling of contact killing type tool, is used for cauline leaf processing in seedling stage, contacts by blade and works.When using in dry land, first permeate by the blade face and be transmitted to inhibited photosynthesis in chloroplast.Can permeate and can pass through root absorption by the blade face when using in the paddy field, be transmitted to cauline leaf, strongly hinder weeds photosynthesis and water metabolism, cause nutrition hunger, physiological function is lacked of proper care and lethal.Bentazone active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, to crop safety, in 6-18 week after dispenser, can be decomposed by microorganism in soil.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Fluazifop-p-butyl has another name called efficient fluazifop, chemical name: (R)-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 the annual and perennial grassy weeds such as barnyard grass, wild oat, green foxtail, Setaria glauca, 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 the dispenser of seedling band all can.The little use of weed size is hanged down dose, and leaf age is large uses high dose; In the situation that moisture condition is good with low dose, use high dose under drought condition.Efficient fluazifop is invalid to broadleaved herb and nutgrass flatsedge, and the impact of its herbicidal effect climate and rainwater is serious, therefore, be subject in the use the impact that local climate changes, 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)-2-nitrobenzoic acid sodium is a kind of diphenyl ether herbicide.Its structural formula is:
Acifluorfen is a kind of tagging property weed killer herbicide, early time treatment after 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 suppress the transmission of mitochondria electronics, to cause the stagnation of respiratory system and energy production system, suppress cell division and make weeds dead.This weed killer herbicide can be prevented and treated the annual broadleaf weeds such as black nightshade in Soybean Field, 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, will strictly control consumption in use procedure, or with other herbicide mixtures, reduce poisoning and improve preventive effect to grassy weed.
Soybean field herbicide is limit by crop safety at present, the herbicide spectrum is also limited, be used alone the weed killer herbicide single dose and can not control completely effectively the generation of soybean weeds, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all easily causes 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 is to provide the application of this weed killer herbicide.
A kind of mixed herbicide that contains bentazone, acifluorfen and fluazifop-p-butyl, it is characterized in that this weed killer herbicide is take bentazone, acifluorfen and fluazifop-p-butyl as main active ingredient, 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 pesticidal preparations and be mixed with any one formulation that allows on agricultural chemicals.Preferably be processed into the 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 various grass family or broad leaved weed in preventing and kill off Soybean Field.
Herbicidal composition of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal composition of the present invention can kill weeds by three kinds of different mechanism, makes Weed Resistance produce Speed Reduction, has greatly improved the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.The herbicide of three kinds of weed killer herbicides spectrum is different, and the three is combined herbicidal spectrum and the activity of these three kinds of medicaments with the be mixed medicament that makes of special ratios, makes the herbicidal spectrum of mix preparation wider, and the lasting period is longer.
3, delay Weed Resistance.The present invention can significantly improve the preventive effect to various resistant weeds, delays the generation of herbicide resistance, extends the service life of medicament.
4, safe.Herbicidal composition of the present invention is applied to the Soybean Field postemergence weed control, and it can prevent and kill off various grass family or broad leaved weed in Soybean Field, under the prerequisite that has improved drug effect, soybean and succession crop is all had safety.
