Abstract
The invention discloses a weeding composition comprising tembotrions, isoxaflutole and fluroxypyr, the effective ingredients are tembotrions, isoxaflutole and fluroxypyr, the weeding composition comprises commonly used additives, the mass fraction ratio of tembotrions to isoxaflutole to fluroxypyr in the composition is (1-20):(1-20):(1-20), and the weight percentage of the sum of the weights of the effective ingredients in the weeding composition is 1%-60%. The weeding composition has a remarkable synergistic effect, the use amount of the effective ingredients of the compound agent is remarkably reduced as compared with the exclusive use amount of the effective ingredients, and the weeding composition is suitable for preventing and killing weeds in a corn field at the 3-5 leaf stage, and is more suitable for even spraying.
Description
Technical field
Composition pesticide according to the present invention, be with ring sulphur ketone, isoxaflutoles, fluroxypyr as effective ingredient,
For preventing and treating farmland weed, it is particularly useful for preventing and kill off corn field annual gramineous weed and broad leaved weed.
Background technology
Chemical method weeding is agriculturally to control one of Main Means of weeds.In recent years, due to some herbicide kinds
Large area is used alone, and already leads to many weeds and develops immunity to drugs.Meanwhile, grass when weeds occur is mutually complicated, not only 1 year
The mixed life of raw and perennial weeds, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, and low age, advanced age are miscellaneous
Grass staggeredly occurs, so when herbicide kind is used alone, can show defect in a certain respect and limitation.
Ring sulphur ketone, three ketones corn field herbicide, its activity are higher than nitre sulphur ketone (mesotrione, mesotrione), to making
Thing safety, is mainly used in the preventing and treating of corn field annual gramineous weed, while also having certain preventive effect to broad leaved weed；Ring sulphur
Ketone can efficiently prevent and kill off resistance green Herba Setariae Viridis, resistance barnyard grass, resistance open country broom corn millet, resistance open country broomcorn millet and resistance to Semen Maydiss high safety
The noval chemical compound of property of medicine weeds Digitaria ischaemum (Schreib.) Schreib. Ex Mubl..
Isoxaflutole is done in a kind of organic heterocyclic class selectivity of soil treatment for the Dry crop such as Semen Maydiss, Caulis Sacchari sinensis field
Suction type herbicide before seedling stage, mainly works via weeds young root Assimilation and conductivity.After susceptible weeds absorb this medicine, by suppression
Ethyl-para-hydroxyphenyl ketone dioxygenase processed and destroy chlorophyllous formation, cause aggrieved weeds chlorosis wither.Isoxaflutole is being applied
When or apply after, though the effective ingredient being stranded in topsoil because soil moisture content is bad can not give play to anti-remove impurity in time
The effect of grass, but remain to be kept for the long period be not decomposed, rainfall to be run into or irrigation, remain to play the effect of management of weeds,
Susceptible weeds even to growing to 4~5 leaves can also be killed and be suppressed.
Fluroxypyr is the inner sucting conduction type herbicide after seedling of LG-DOW exploitation, is absorbed by plants after medicine quickly,
Sensitive plant is made the reaction of classical hormones class herbicide occur, plant deformity, distortion are final withered.Suitable for Semen Tritici aestivi, Fructus Hordei Vulgaris,
Prevent and kill off broad leaved weed in the ground such as Semen Maydiss, Fructus Vitis viniferae, orchard, pasture, forest land, lawn；Such as Herba Galii Teneri, volume stem smartweed, Herba Portulacae, Herba Solani Nigri, field
Flos Calystegiae sepii, knotweed, Herba Amaranthi tricoloriss etc., it is invalid to grassy weed.
During the single use of ring sulphur ketone, isoxaflutole, fluroxypyr, there are certain defect and limitation.
The present inventor is had made intensive studies to the mixture of ring sulphur ketone, isoxaflutoles, fluroxypyr, substantial amounts of
On the basis of formula indoor screening test and field medicine effect test, it is found that ring sulphur ketone, isoxaflutoles, fluroxypyr are carried out
Mixture, in the range of certain mixed ratio shows obvious potentiation, after further study, completes to corn field weed
The present invention.
Ring sulphur ketone, isoxaflutoles, the mixture of fluroxypyr and application there is no report at present.
The content of the invention
It is an object of the invention to develop immunity to drugs to farmland weed in solving prior art problem and actual prevention effect
It is poor, there is provided one kind is efficiently, low toxicity, quick-acting are good and the lasting period is long, are conducive to the Herbicidal combinations of farmland weed comprehensive control.
It is a further object of the present invention to provide being used to prevent and kill off farmland weed by the Herbicidal combinations, it is particularly useful for preventing and kill off Semen Maydiss
Annual gramineous weed and broad leaved weed etc..
Technical solution of the present invention：With ring sulphur ketone, isoxaflutoles, fluroxypyr as effective ingredient, mixture medium ring
Sulphur ketone, isoxaflutoles, the quality parts ratio of fluroxypyr are 1-20,1-20,1-20, and remaining is permission use in pesticide
With acceptable auxiliary element.
The known method of Herbicidal combinations of the present invention is prepared into any one dosage form for being adapted to agriculturally use, relatively good
Dosage form be the common dosage forms such as suspending agent or water dispersible granules in one kind, in preparation effective ingredient total content be 1%~60%.
Auxiliary agent used in the present composition includes solvent, dispersant, stabilizer, emulsifying agent, antifreezing agent, thickening agent etc.
And other are beneficial to effective ingredient known substance that is stable and playing drug effect in the formulation, are all conventional or permissions in pesticidal preparations
The various composition for using, is not particularly limited, and concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can be provided in the form of finished product preparation, i.e., in compositionss, each material is blended, group
The composition of compound can also the form of single dose provide, directly mixed in tank or bucket using front, it is dense required for being then diluted to
Degree.The frequency of administration and amount of application of the present composition changes with weather condition and crop condition and changes, can be by using
Appropriate dosage form reaches the purpose of preventing and treating.
The present composition is primarily adapted for use in preventing and treating corn field annual grassy weeds.
Compared with prior art, the beneficial effects of the present invention is, compounding improves preventing and treating with obvious potentiation
Effect；Expand preventing and treating spectrum；Two kinds of effective ingredient compounding, reduces Pesticide use amount, so as to reduce cost and reduce it is right
The pollution of environment.
Specific embodiment
