Description
Technical field
The invention belongs to mixture of herbicides field, particularly relate to a kind of containing dichloroquinoline oxadiazon and different grass pine remove
Grass compositions.
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
Point be weeds root, leaf Assimilation and conductivity 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.
Different grass pine is a kind of selective herbicide, and applicable crops is quite varied, the most at home Semen sojae atricolor, Caulis Sacchari sinensis, Oryza sativa L.,
Brassica campestris L all obtains registration.Different grass pine can suppress the pigment synthesis of weeds, after the root of weeds, plumelet, absorption medicament, to uploading
Leading, be diffused into blade through xylem, the pigment synthesis of suppression weeds presents albinism, makes weeds can not pass through photosynthesis system
Make nutrient substance, finally dead because nutrition exhausts.Sand soil is in the case of rainy, or temperature low soil moisture is bigger
In the case of.Different grass pine broad weed-killing spectrum, can prevent and kill off annual multiple grassy weed and broad leaved weed such as: barnyard grass, Herba Digitariae, cattle
Muscle grass, Herba Setariae Viridis, Herba Abutili, Semen Euphorbiae, few, Herba Solani Nigri, Herba stellariae mediae etc..
Reasonably chemical herbicide mixture has expansion weed control spectrum, improve preventive effect, reduce dosage, reduce key,
Reduce residual, delay feature, mixture of herbicides or the mixtures such as drug-fast generation and development to be having the most of solution the problems referred to above
One of method of effect.Present inventor, on the basis of lot of experiments, filters out dichloroquinoline oxadiazon and different grass pine
Complex weedicide, this complex weedicide has obvious potentiation in certain scope.Currently, with respect to dichloroquinoline oxadiazon
Complex composition and application with different grass pine there is no people's report.
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 integrated control of thing, beneficially crop weeds, described activity of herbicidal compositions composition comprises dichloroquinoline oxadiazon and different
Grass pine.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of containing dichloroquinoline oxadiazon and different grass
The Herbicidal combinations of pine, wherein, dichloroquinoline oxadiazon is 1:50-25:1, preferably 1:20-20 with the weight ratio of different grass pine:
1。
The herbicidal composition of the present invention can be aided with pesticide auxiliary element and be prepared by customary preparation methods applicable
Any one dosage form agriculturally used, such as, can be wettable powder, water dispersible granules, aqueous emulsion, microemulsion, suspension
Agent, dispersible oil-suspending agent, dry suspending agent etc..
Further, in the Herbicidal combinations of the present invention, the weight ratio of active component is 0.1-90%.
The Herbicidal combinations of the present invention may also include the herbicide of other agricultural active composition, such as other kind, parasite killing
Additive conventional in agent, antibacterial, fertilizer and herbicides and safeners and/or plant protection and/or insecticides adjuvant, or can be with them
It is used together.
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.
