Abstract
The invention discloses a kind of pyrazoles of grass containing sulphonyl and the mixed herbicide of pyribenzoxim, for the herbicide using sulphonyl grass pyrazoles and pyribenzoxim as principle active component, the mass ratio of sulphonyl grass pyrazoles and pyribenzoxim is 1~68：1~68.Application of the mixed herbicide of the present invention in wheat paddock postemergence weed control, has the advantages that wide spectrum, quick-acting, efficient, less toxic, safety and environmental protection.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, it is related to sulphonyl grass pyrazoles and pyribenzoxim
Binary built agent.The herbicidal composition can be applied to wheat paddock postemergence weed control.
Background technology
Sulphonyl grass pyrazoles (pyrasulfotole), chemical name：(5- hydroxyl -1,3- dimethyl pyrazole -4- bases) (α, α,
The fluoro- 2- mesyls of α-three-p- tolyl) ketone, structural formula is：Sulphonyl grass pyrazoles is Bayer
Crop science belonged to benzoylpyrazole class compound, is HPPD inhibitor in the new herbicides found in 1999.Due to
Suppression to HPPD suppresses the biosynthesis of carotenoid indirectly, as a result causes plant meristem to produce alphosis, finally
Cause death.The herbicide has wide spectrum removing activity, and before seedling, after seedling can be used, due to wheatland long-time service sulfonylurea
Herbicide prevents and kill off broad leaved weed, causes many resistance broad leaved weeds to occur, and rise to dominant population in some areas.The product
Appearance can solve the problems, such as wheatland resistant weed well.Main control object includes chickweed, lamb's-quarters, black nightshade, amaranth, piemarker
The broad leaved weeds such as numb, spontaneous rape, duck wheat.
Pyribenzoxim (pyribenzoxim), chemical name：O- [double (4,6- dimethoxy -2- pyrimidine radicals) oxygen of 2,6-
Base] benzoylbenzophenone oxime, structural formula is：Pyribenzoxim is wide spectrum selectivity bud
Herbicide afterwards, belongs to acetolactate synthestase (ALS) inhibitor, has interior suction and local conduction.It can be inhaled by plant stem-leaf
Receive, conduct in vivo, influence the activity of acetolactate synthestase, suppress the synthesis of sensitive plant branched-chain amino acid, susceptible weeds
After absorbing medicament, young shoot and root stop growing, and tender tissue such as lobus cardiacus turns to be yellow, and subsequent whole strain is withered.Numerous grass can be prevented and kill off
Section weeds and broad leaved weed.Grassy weed such as amur foxtail, lady's-grass, barnyard grass, green bristlegrass, annual bluegrass, Bermuda grass etc.；Broad leaved weed
As piemarker, ambatch, Amaranthus retroflexus, big bur beggar-ticks, Cassia, lamb's-quarters, field bindweed, clearvers, purslane, sheep hoof, knotweed, sesbania, black nightshade,
Chickweed, dandelion, heartsease, Noogoora burr.It can suppress weed growth after dispenser, but chemical weeding speed is slower.
Wheat field herbicide is limited by crop safety at present, and herbicide controlling spectrum is also limited, and a kind of herbicide single dose is used alone
Cannot completely effectively control the generation of weeds of wheat, furthermore some herbicides due to the water-soluble big or field lasting period too
Short, dosage is excessive or the uneven residual hazard all be easy to causeing to this season crop or succession crop of dispenser.Therefore, it is of the invention
Select can herbicide controlling spectrum it is different, the sulphonyl grass pyrazoles of advantage and disadvantage complementation is made into conjunction after being suitably reduced with two kinds of herbicides of pyribenzoxim
Agent uses, and not only expands herbicide controlling spectrum, hence it is evident that improves herbicidal effect, it also avoid producing this season crop poisoning and to rear stubble
Crop produces the possibility of residual hazard.
The content of the invention
The object of the present invention is to provide a kind of pyrazoles of grass containing sulphonyl and the mixed herbicide of pyribenzoxim.
It is a further object of the present invention to provide application of the herbicide in wheat paddock weeding.
A kind of mixed herbicide of the pyrazoles of grass containing sulphonyl and pyribenzoxim, it is characterised in that the herbicide is with sulphonyl grass pyrrole
Azoles and pyribenzoxim be principle active component, and the mass ratio of sulphonyl grass pyrazoles and pyribenzoxim is 1~68：1~68.It is preferred that
The mass ratio of sulphonyl grass pyrazoles and pyribenzoxim is 1~60：1~61, more preferably 6~59：1, most preferably 12~
24：1.
In mixed herbicide, sulphonyl grass pyrazoles is 1 with mass percentage of both pyribenzoxims in herbicide
~85%, preferred mass percentage composition is 10~80%, more preferably 25~65%.
In the sulphonyl grass pyrazoles of the present invention and the binary built preparation of pyribenzoxim, except sulphonyl grass pyrazoles and pyrimidine oxime
Outside the active ingredients such as careless ether, the conventional surfactants allowed on pesticidal preparations, antidote, thickener, solvent can also be added
Or the auxiliary agent such as solid packing is configured to any one formulation for allowing on pesticide.It is preferred that be processed into missible oil, suspending agent, aqueous emulsion,
Microemulsion, wettable powder, water dispersible granules.
Application of the mixed herbicide of the present invention in wheat paddock weeding, the grass family especially in wheat paddock is prevented and kill off
Weeds and the application of broad leaved weed, have the advantages that broad weed-killing spectrum, quick, low, the less toxic, safety and environmental protection of residual, are good
Wheat crop chemical herbicide.
Compared to the prior art, beneficial effects of the present invention：
The combinations of herbicides of the present invention, it is excellent with broad weed-killing spectrum, quick, efficient, less toxic, the low, safety and environmental protection of residual etc.
Point, it is possible to reduce the advantages that pesticide usage amount, reduces pesticide residue, and Environmental compatibility is good, to safety of human and livestock, is good wheat
Crop chemistry herbicide.
1st, activity of weeding is high.The Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism so that weeds
Resistance produces speed and reduces, and effective ingredient consumption reduces, but drastically increases the removing activity of herbicide.
2nd, herbicidal spectrum is wide, lasting period length.Sulphonyl grass pyrazoles is mainly used for preventing and kill off broad leaved weed, and pyribenzoxim is broad spectrum activity
Herbicide, available for preventing and kill off grassy weed and part broad leaved weed.After both mixing, it is possible to increase to grassy weed and wealthy
The prevention effect of leaf weeds.
3rd, Weed Resistance is delayed.Herbicidal combinations of the present invention reduce resistance of the weeds to medicament, and carry by binary built
The preventive effect of high antagonism weeds, so as to extend the service life of medicament.
4th, it is safe.Since the use content of various active ingredients reduces, medicament is set to improve the premise of drug effect
Under, pesticide residue is reduced, it also avoid also being improved to wheat and succession crop security, avoid pesticide to people
Livestock products give birth to the possibility of residual hazard.
