Abstract
The invention discloses a mixed herbicide composition containing bispyribac-sodium and pyriftalid. The herbicide composition adopts the bispyribac-sodium and the pyriftalid as main active components, the weight ratio of the bispyribac-sodium and the pyriftalid is 1 to 99:1 to 99. Different surfactants, thickening agents, solvents, solid fillers or the like can be added to the herbicide composition to become a variety of agents, such as emulsifiable concentrate, suspending agents, emulsion in water, dry suspension, water-dispersible granules, wettable powder and the like. The herbicide composition can prevent and get rid of gramineous weeds, broadleaf weeds and cyperaceous weeds in paddy fields, and compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the pesticide effect is enhanced, has a broad weeding spectrum and long persistence period, is safe for rice and next-stubble crops, and therefore is an ideal paddy field herbicide.
Description
Technical field
The invention belongs to pesticide field, especially weed killer herbicide field, relates to the mixed herbicidal composite of two careless ether and pyriftalid.This Herbicidal combinations can be applied paddy field postemergence weed control.
Background technology
Two careless ether, has another name called Nong Meili, salicylic acid Sulfadiazine Compound, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of chemical name: 2,6-.Belong to phenoxy carboxylic acid herbicides, mainly by the acid of root leaf absorption inhibition vinegar milk is synthetic, hindered aminoacid biosynthesis side chain is selective herbicide, rice direct-seeding Tanaka, uses, and herbicidal spectrum is wide.Its structural formula is as follows:
Pyriftalid, chemical name: 7-[(4,6-dimethyl-2 pyrimidine radicals) sulphur]-3-methyl isophthalic acid (3H)-isopropyl furanone, structural formula is:
This medicine belongs to miazines oxygen (sulphur) benzoates weed killer herbicide, is early stage broad-spectrum herbicide after rice seedlings, aims at and transplants and direct seading rice exploitation.Its mechanism of action is suppress acetolactate synthestase (ALS) synthetic.Be used for preventing and treating paddy field grassy weed and part broad leaved weed, at paddy field, pyriftalid is absorbed by paddy rice root tip, and seldom a part can be transmitted on blade, and the grass cutting blade that small part medicament can be sprouted absorbs.
At present, herbicide for paddy field is limit by crop safety, herbicide spectrum is also limited, uses separately a kind of weed killer herbicide single dose can not control completely effectively the generation of paddy field weed, moreover weed killer herbicide consumption is excessive or dispenser is inhomogeneous also easily causes the residual hazard to this season crop or succession crop.Therefore, the present invention selects the two careless ether of pluses and minuses complementation and pyriftalid to be made into combination agent use, the consumption that had so both reduced medicament, has obviously improved herbicidal effect, has also avoided this season to make deposits yields poisoning and the possibility to succession crop generation residual hazard.
Summary of the invention
The present invention is according to the present situation of current paddy field herbicide after seedling, and after paddy field seedling weeds a situation arises, provide a kind of by two careless ether and the composite binary mixed herbicidal composite of pyriftalid, this Herbicidal combinations can not only improve the preventive effect to weeds, and to when stubble and succession crop safety, reduced peasant's drug cost simultaneously.
The object of this invention is to provide a kind of mixed herbicidal composite containing two careless ether and pyriftalid, it is characterized in that this Herbicidal combinations is take two careless ether and pyriftalid as main active ingredient, the mass ratio of two careless ether and pyriftalid is 1～99: 1～99.The mass ratio of preferably two careless ether and pyriftalid is 1～50: 1～50, and further the mass ratio of preferably two careless ether and pyriftalid is 1～30: 1～30, and most preferably the mass ratio of two careless ether and pyriftalid is 1～10: 1～15.
In mixed herbicidal composite, the two quality percentage composition in Herbicidal combinations of two careless ether and pyriftalid is 1～85%, and preferred mass percentage composition is 10～80%.
In the binary built preparation of two careless ether of the present invention and pyriftalid, except two kinds of active ingredients, the auxiliary agent allowing on the agricultural chemicals such as different surfaces activating agent, thickener, solvent or solid packing can also be added, the multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder can be processed into.
This Herbicidal combinations can, with respect to single dose having improved under the prerequisite of drug effect, delay Weed Resistance, and herbicidal spectrum is wide, and the lasting period is long, enough prevents and kill off paddy field annual gramineous weed, broad leaved weed and sedge weed, and to paddy rice and second stubble crop safety.Herbicidal combinations of the present invention can be used for preparing the weed killer herbicide of paddy field postemergence weed control, can be used in especially preparation and prevent and kill off the weed killer herbicide of various annual weed and perennial weed, especially can prepare the weed killer herbicide of preventing and kill off grassy weed, broad leaved weed and sedge weed.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism, makes Weed Resistance produce Speed Reduction, greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Two careless ether is broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and pyriftalid is to be mainly to prevent and kill off grassy weed, the weed killer herbicide of sedge weed and part broad leaved weed.After both mix, can improve the preventive effect that has of the preventive effect, particularly annual gramineous weed of grassy weed and broad leaved weed and sedge weed and broad leaved weed and sedge weed, thereby extend the lasting period of medicament.
3, safe.Medicament of the present invention is improving under the prerequisite of drug effect, and its safety to paddy field and succession crop is also improved.
