Abstract
The present invention relates to the Herbicidal combinations containing dichloroquinoline oxadiazon and Oxadiargyl, described Herbicidal combinations is according to having synergistic function, and wherein, the weight ratio of dichloroquinoline oxadiazon and Oxadiargyl is 1:50 50:1.
Description
Technical field
The invention belongs to mixture of herbicides field, particularly relate to a kind of containing dichloroquinoline quinoline oxadiazon and Oxadiargyl
Herbicidal combinations, this Herbicidal combinations herbicidal effect is good, and the lasting period is long.
Background technology
Dichloroquinoline oxadiazon, chemical name is 2-(3,7-dichloroquinoline-8-base) carbonyl-Ketohexamethylene-1,3-diketone, CAS
Number it is 1350901-36-8, is the new herbicides of China's independent research, main absorb be used for preventing and kill off by weeds root, stem, leaf
Gramineous crop compares difficult barnyard grass, Herba Setariae Viridis, Herba Digitariae and the multiple broad leaved weed prevented and kill off the most at present, after weeds dispenser,
By blade or root absorption, dividing a word with a hyphen at the end of a line up and down in plant, pass to rapidly whole plant, it is HPPD inhibitor, and it acts on spy
Weeds root, leaf Assimilation and conductivity during point and work, after susceptible weeds absorbs this medicine, double by suppression p-hydroxybenzene pyruvate
Oxidasic synthesis, causes the accumulation of tyrosine, makes the biosynthesis block of plastoquinone and tocopherol, and then has influence on carotenoid
Biosynthesis, weeds occur after albefaction dead.
Oxadiargyl, belongs to diazole type herbicides, and the mechanism of action is the inhibitor of proporphyrinogen oxidase, available
In preventing and kill off annual gramineae, Cyperaceae and broad leaved weed and some perennial weeds.
By the screening of the pesticide species compounded formula of the different mechanisms of action, weed control spectrum can be expanded, improve prevention effect,
Reduce dosage, delay the multiple advantages such as drug-fast generation.Present inventor is at lab screening and the base of field test
On plinth, filter out the complex composition of dichloroquinoline oxadiazon and Oxadiargyl, there is obvious potentiation, and about both
Herbicidal combinations and application there is no people at present and reported.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of efficient, Herbicidal combination of low toxicity, low cost
The comprehensive control of thing, beneficially crop weeds, the active component of described compositions includes dichloroquinoline oxadiazon and propine grass
Ketone.
The Herbicidal combinations of the present invention also can comprise other active component, be selected from herbicide, insecticide, antibacterial and
Additive conventional in the pesticide activity component of safener and/or plant protection and/or formulation auxiliary agents, or can make together with which
With.
The herbicidal composition of the present invention has synergistic function so that the consumption of each active component reduces or phase
Strengthen with the drug effect under consumption, it is however generally that, in compositions, the weight ratio of dichloroquinoline oxadiazon and Oxadiargyl is 1:80-
80:1, preferably 1:50-50:1, most preferably 3:2.
In the Herbicidal combinations of the present invention, the content of active component can use in wider scope, such as percentage composition
Can be 1-90%, preferably 20-70%, more preferably 30-50%.
The Herbicidal combinations of the present invention can be with the auxiliary element of routine in formulations of pesticide processing according to customary preparation methods
Prepare the most possible dosage form, such as wettable powder, water dispersible granules, aqueous emulsion, microemulsion, suspending agent, solubility
Liquor, dispersible oil-suspending agent, dry suspending agent etc..
Further, the Herbicidal combinations of the present invention may be used for preventing and kill off in various crop grass family, broad-leaved, Cyperaceae
Weeds.
The use frequency of the Herbicidal combinations of the present invention and usage amount little change with crops, weeds, weather condition,
The purpose effectively prevented and treated can be reached by using suitable dosage.
Compared with prior art, the invention have the benefit that the effect machine of effective ingredient in described Herbicidal combinations
Manage different, by being used by the mixture of herbicides of the different mechanisms of action, the generation of herbicide resistance can be delayed；The present invention
Herbicidal combinations between there is obvious potentiation, can significantly improve preventive effect, extend the useful life of medicament, subtract
Lack the usage amount of pesticide and the risk to environment, meet the demand of " pesticide zero growth rate "；Additionally, the combinations of herbicides of the present invention
Thing safety is high, on the premise of improving drug effect, also has the highest safety to crops.
Detailed description of the invention
In order to be better understood from the essence of the present invention, below in conjunction with embodiment, present disclosure is described further,
But can not be considered as limitation of the present invention, the following stated is only used for explaining the present invention, for without departing from present invention spirit and principle

Two, toxicity measures
1, Application Example 1: the biological of paddy field weed is lived by dichloroquinoline oxadiazon with Oxadiargyl and mixture compositions thereof
Property measure report
Experiment purpose: measure dichloroquinoline oxadiazon and Oxadiargyl and different blended combo compound barnyard grass thereof under the conditions of greenhouse pot culture
Grass preventive effect after 7 days, and have rated its synergy, for formulation development and the examination of agriculture chemical registration field efficacy of Mixed Pharmacy
Offer scientific basis is provided.
For examination target: barnyard grass (Echinochloa crusgalli).
Evaluation methodology: evaluating herbicide mode of application according to Colby method, its formula is: E0=X+Y-XY/100
X, Y respectively dichloroquinoline oxadiazon and the Oxadiargyl preventive effect to weeds when dosage is a or b；E0For dichloroquinoline
Oxadiazon and Oxadiargyl are in the desired value that dosage is during a+b, when the observed value of herbicidal composition is more than according to Colby method
Desired value time, i.e. think the compounding synergistic function that shows of dichloroquinoline oxadiazon and Oxadiargyl, result of the test is shown in
Table 1.
As can be seen from Table 1, after dichloroquinoline oxadiazon is mixed with Oxadiargyl, more respective alone phase comparison rice terrace barnyard grass has
Extraordinary preventive effect, has substantially then potentiation, is worth popularization and application on producing.
2, field control effectiveness test
This test is located at San Shui town, suburb, Fushan City, Guangdong Province, red earth, PH6.0, and organic matter 1.3%, medium fertility, water waters
Condition is good.Spraying period is on May 3rd, 2016, and weather is fine, temperature 26-32 DEG C, first venting water in field before spray medicine, makes miscellaneous
Grass surfaces, and after spray medicine, continuous dry field 5 days, then keep 3-5 centimetre of shallow water 7 days, finally recover normal field management；Oryza sativa L.
Kind is that Foshan oil accounts for (hybrid paddy rice), and during spray medicine, Oryza sativa L. is in the 3-4 leaf phase, and weeds are in 3-5 leaf phase, field main weeds kind
For rice barnyard grass (coverage accounts for whole weed community 75%).Plot area 67 square metres, is repeated 4 times, and random district group arranges.Respectively at
15 days, 30 days investigation preventive effects after medicine.Result of the test is shown in Table 2.
Field control effectiveness test result shows, after dichloroquinoline oxadiazon and Oxadiargyl mixture, to rice terrace barnyard grass preventive effect
Good, and production-increasing function is obvious, in scope of medication, does not finds have poisoning to produce Oryza sativa L., it is seen then that dichloroquinoline oxadiazon and propine
The compounding of benfluralin is worth popularization and application on producing.
The illustrative embodiments that above-described embodiment uses only for explanation inventive principle, but the present invention is not limited only to
This, those skilled in the art, without departing under real situation of the present invention, can make various improvement and change, and these improve and become
More fall within protection scope of the present invention.
