Abstract
The invention belongs to the field of pesticides and discloses a herbicidal composition containing high-efficiency haloxyfop and quizalofop-P-tefuryl and application thereof. The main active ingredients of the herbicidal composition are high-efficiency haloxyfop and quizalofop-P-tefuryl in a mass ratio of 1-70:1-80, wherein the high-efficiency haloxyfop and the quizalofop-P-tefuryl account for 1 to 85 percent of the total mass of the herbicidal composition. The herbicidal composition provided by the invention can be used for controlling postemergence weeds in a soybean field, and particularly has remarkable effects when used for controlling various poaceae weeds in the soybean field. Compared with a single-component herbicide, the herbicidal composition reduces dosage, delays the resistance of the weeds, has a broad herbicidal spectrum and acts for a long time on the premise of improving herbicide effects, and is safe for corn 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 haloxyfop-methyl spirit and quizalofopPtefuryl.
Technical background
The efficient haloxyfop-methyl spirit has another name called haloxyfop-r-methyl, chemical name: 2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxygen base) phenoxy group] methyl propionate.Belonging to phenoxy carboxylic acid herbicides, is the fatty acid synthetic inhibitor, is fluorinated heterocycle highy potent herbicide of new generation.This medicament is the inner sucting conduction type weed killer herbicide, is absorbed by blade, stem stalk and root system, suppresses the biosynthesis of fatty acid in plant corpus, and cell growth, division are stopped, and cell membrane etc. contain the fat structural deterioration and cause weeds death.Can be absorbed very soon after this weed killer herbicide cauline leaf is handled, conduct to whole plant, suppress the plant meristematic tissue and kill dogstail by the leaf of grass family class grass.The medicament that sprinkling falls into soil is easily absorbed by root, also can play and kill grass effect, average 55 days of half life period in soil.Compare with cover grass energy, haloxyfop-r-methyl is structurally with the ethoxyethyl in the methyl substituted cover grass energy; And owing to the a-carbon of propionic acid in the cover grass energy structure is asymmetric carbon atom, so have R and two kinds of optical isomers of S, wherein the S body does not have activity of weeding, and haloxyfop-r-methyl is highly finished product (R body) of having removed non-active portion (S body).It is active higher than cover grass energy under the Isodose, and efficacy stability is subjected to adverse environment condition influence such as low temperature, rainwater few.Behind the medicine after one hour rainfall just very little to drug effect influence.Divide evil, the annual and perennial standing grain herbaceous weed at heading initial stage to arriving behind the seedling, good preventive effect is arranged, invalid to broadleaved herb and nutgrass flatsedge, and its herbicidal effect is influenced seriously by weather and rainwater, therefore, be subject to the influence that local climate changes in the use, in addition, because this medicament is used in the soybean field for a long time, some weeds have produced serious resistance to it.
QuizalofopPtefuryl has another name called spray spy, the careless ester of health.Chemical name: (RS)-2-methylfuran hydrogen ester base (R)-2-[4-(6-chloro-2-quinoxaline oxygen) phenoxy group] ethyl propionate is a kind of acetyl-CoA carboxylase (ACCase) inhibitor.Can be absorbed very soon after cauline leaf is handled, conduct to the meristematic tissue of whole plant, suppress the synthetic of fatty acid, stop germination and root growth and kill weeds by the grassy weed cauline leaf.QuizalofopPtefuryl lasting period in the weeds body is longer, and weeds stop growing very soon behind the spray medicine, 3-5 right overhead leaf base browning, and obvious flavescence necrosis appearred in weeds in 5-10 days, whole strain death in 14-20 days.At present, quizalofopPtefuryl is mainly by import, the price comparison height, and therefore unit are use cost height has restricted the usage amount of this medicament.
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 defective that the objective of the invention is to overcome above-mentioned prior art provides a kind of Herbicidal combinations that contains efficient haloxyfop-methyl spirit and quizalofopPtefuryl.This Herbicidal combinations, has reduced dosage and has delayed the weeds resistance under the prerequisite that has improved drug effect with respect to single agent, and herbicidal spectrum is wide, and the lasting period is long, and corn and succession crop are all had safety.
Another object of the present invention provides the application of this Herbicidal combinations in the weed killer herbicide of preparation soybean weeds.
A kind of Herbicidal combinations that contains efficient haloxyfop-methyl spirit and quizalofopPtefuryl is characterized in that this Herbicidal combinations is main active ingredient with the efficient haloxyfop-methyl spirit with quizalofopPtefuryl, and the efficient haloxyfop-methyl spirit is 1～70: 1～80 with the mass ratio of quizalofopPtefuryl.Preferred efficient haloxyfop-methyl spirit is 1～50: 1～60 with the mass ratio of quizalofopPtefuryl.
In Herbicidal combinations, the efficient haloxyfop-methyl spirit is 1～85% with the two quality percentage composition in Herbicidal combinations of quizalofopPtefuryl, and the preferred mass percentage composition is 10～75%.
In the binary built preparation of efficient haloxyfop-methyl spirit of the present invention and quizalofopPtefuryl, except active ingredients such as efficient haloxyfop-methyl spirit and quizalofopPtefuryl, 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 soybean Tian Miaohou weeds, particularly prevents and kill off to use in the weed killer herbicide of soybean Tanaka grassy 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.The efficient haloxyfop-methyl spirit is the broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and quizalofopPtefuryl is a weed killer herbicide of preventing and kill off grassy weed.Both can improve the preventive effect to multiple annual gramineous weed and perennial grassy weed, thereby prolong the lasting period of medicament 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.
