Abstract
The invention discloses a herbicide composition containing fluazifop-p-butyl and sethoxydim and application thereof. In the herbicide composition, the fluazifop-p-butyl and the sethoxydim are taken as the main active ingredients; and the mass ratio of the fluazifop-p-butyl to the sethoxydim is 1-70: 1-80, and the fluazifop-p-butyl and the sethoxydim account for 10 to 85 percent of the total mass of the herbicide composition. The herbicide composition can be used for preparing herbicide for controlling post-emergence weeds in a soybean field, and particularly has an obvious effect when used for preparing herbicide for controlling various graminaccae and broadleaf weeds in the soybean field. Compared with a single-composition herbicide, the herbicide composition postpones the resistance of weeds, has a broad herbicide spectrum and acts for a long time on the premise of improving herbicide effect, and is safe for the rapes and the 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 sethoxydim.
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.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.And its herbicidal effect influences seriously by weather and rainwater, therefore, is subjected to the influence that local climate changes in the use.
Sethoxydim has another name called Sethoxydin.Chemical name: (±) 2-[1-(ethoxy imino) butyl-5-(2-ethylsuleenyl propyl)-3-hydroxyl-2-cyclohexene-1-ketone, structural formula is:
This weed killer herbicide is the strong inner sucting conduction type cauline leaf inorganic agent of selectivity, can be absorbed rapidly by the grassy weed cauline leaf, and be transmitted to top and internode meristematic tissue, and its cell division is destroyed.Begin necrosis by growing point and internode meristematic tissue, stopped growing after 3 days by the medicine plant, young leaves fades or cyanine plain color occurs after 7 days, and 2-3 week complete stool is withered.This agent selectivity between grass family and dicotyledon is very high, to broad leaf crop safety.The sethoxydim conductivity is strong, but in all dispensers between a tillering stage of Gramineae ruderal 2 leaves to 2.Rainfall does not influence drug effect substantially.Can be used for soybean, cotton, rape, peanut, beet, flax, broad-leaved vegetables, potato and orchard, nursery control cogongrass, grape wheatgrass, Bermuda grass etc.But it is invalid to broad leaved weed, because sethoxydim is used in the soybean field for a long time, some weeds such as annual bluegrass, bavin fescue grass etc. 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 sethoxydim.
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 sethoxydim, it is characterized in that this Herbicidal combinations is main active ingredient with efficient fluazifop and sethoxydim, the mass ratio of efficient fluazifop and sethoxydim is 1～70: 1～80, and the mass ratio of preferred efficient fluazifop and sethoxydim is 1～50: 1～60.
In Herbicidal combinations, the two gross mass percentage composition in Herbicidal combinations of efficient fluazifop and sethoxydim is 10～85%, and preferred gross mass percentage composition is 10～75%.
In the binary built preparation of efficient fluazifop of the present invention and sethoxydim, except active ingredients such as efficient fluazifop and sethoxydim, 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 sethoxydim is a 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 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.
