Abstract
The invention discloses a kind of pyrazoles of grass containing sulphonyl and the mixed herbicide of fluoroglycofen-ethyl, for the herbicide using sulphonyl grass pyrazoles and fluoroglycofen-ethyl as principle active component, the mass ratio of sulphonyl grass pyrazoles and fluoroglycofen-ethyl is 1~68：1~68.Application of the mixed herbicide of the present invention in wheat paddock postemergence weed control, there is 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 fluoroglycofen-ethyl
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 right
HPPD suppression suppresses the biosynthesis of carotenoid indirectly, as a result causes plant meristem to produce alphosis, finally leads
It is lethal to die.The herbicide has wide spectrum removing activity, and before seedling, after seedling can be used, because wheatland long-term use sulfonylurea removes
Broad leaved weed is prevented and kill off in careless agent, 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 include chickweed, lamb's-quarters, black nightshade, amaranth, piemarker,
The broad leaved weeds such as spontaneous rape, duck wheat.
Fluoroglycofen-ethyl (fluoroglycofen), chemical name：O- [5- (the fluoro- p- toluene oxygen of 2- chloro- a, a, a- tri-
Base) -2- nitro benzoyls] hydroxyl ethyl acetate, structural formula isFluoroglycofen-ethyl is two
Benzene ether-derivative herbicides, it is protoporphyrin oxidase inhibitor, once being absorbed by plants, only just plays effect under illumination condition.
The compound is reacted with mol-chloric, generates and has virose compound tetrapyrrole to plant cell, gathers and have an effect.Accumulation
During, plant cell membrane is wholly absent, then causes cell inclusion seepage.Available for early soybean, wheat, peanut, water
Rice etc. prevents and kill off that annual broadleaf weed is simultaneous to control grassy weed such as：Barnyard grass, amur foxtail, clearvers, shepherd's purse, lady's-grass, eleusine indica, thousand
Gold, wild oat, Veronica, green bristlegrass etc..
Variety classes herbicide mixture, has that herbicidal spectrum is wide, lifts actual effect, delays herbicide resistance, time and labour saving
Advantage.Screened by formulation of pesticide, actual prevention effect can be effectively improved, reduced dosage, reduce cost, delay disease, worm, grass
The drug-fast generation of evil, it is the important means that agricultural synthesis is administered.Therefore, the present invention selects sulphonyl grass pyrazoles and fluoroglycofen-ethyl
Mixture use is made into after two kinds of herbicides suitably decrement, not only expands herbicide controlling spectrum, hence it is evident that improve herbicidal effect, it also avoid
Poisoning is produced to this season crop and the possibility of residual hazard is produced to succession crop.
The content of the invention
It is an object of the invention to provide a kind of pyrazoles of grass containing sulphonyl and the mixed herbicide of fluoroglycofen-ethyl.
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 fluoroglycofen-ethyl, it is characterised in that the herbicide is with sulphonyl grass pyrrole
Azoles and fluoroglycofen-ethyl be principle active component, and the mass ratio of sulphonyl grass pyrazoles and fluoroglycofen-ethyl is 1~68：1~68.It is preferred that
The mass ratio of sulphonyl grass pyrazoles and fluoroglycofen-ethyl is 1~60：1~61, more preferably 6~59：1, most preferably 24~
59：1.
In mixed herbicide, sulphonyl grass pyrazoles is 1 with weight/mass percentage composition of both fluoroglycofen-ethyls 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 fluoroglycofen-ethyl, except sulphonyl grass pyrazoles and second carboxylic fluorine
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 agricultural chemicals.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, there is broad weed-killing spectrum, quick, low, the less toxic, safety and environmental protection of residual, be high-quality
Wheat crop chemical herbicide.
Compared to the prior art, beneficial effects of the present invention：
The combinations of herbicides of the present invention, have broad weed-killing spectrum, quick, efficient, less toxic, the low, safety and environmental protection of residual etc. excellent
Point, it is possible to reduce pesticide usage amount, reduce residues of pesticides, the advantages that Environmental compatibility is good, to person poultry safety, is high-quality 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 reduced, 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 broad spectrum weeding agent, is mainly used in preventing and kill off broad leaved weed, second
Fluoroglycofen is mainly used in wheat paddock and prevents and kill off that annual broadleaf weed is simultaneous to control grassy weed.After both mixing, it is possible to increase right
Grassy weed and the prevention effect of broad leaved weed.
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.Because the use content of various active ingredients reduces, medicament is set to improve the premise of drug effect
Under, residues of pesticides are reduced, it also avoid also being improved to wheat and succession crop security, avoid agricultural chemicals to people
Livestock products give birth to the possibility of residual hazard.
