Abstract
The invention discloses a kind of Herbicidal combinations containing Mediben, its active component is Mediben, Herba Carpesii macrocephali extract and cottonsedge-like thistle herb extract composition, and weight ratio is 10 40:100‑200:150 300, the Herbicidal combinations can be configured to aqua with surfactant, stabilizer, antifreezing agent and solvent and use, for rice terrace postemergence weed control, particularly have favorable effect, environmentally safe, noresidue to broad leaved weed.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, and in particular to a kind of Mediben is dug with great Hua gold
The ternary built Herbicidal combinations of ear extract and cottonsedge-like thistle herb extract, the Herbicidal combinations can be applied to rice terrace after seedling and remove
Grass.
Background technology
Mediben, also known as wheat straw prestige, Dicamba, chemical name are the chloro- O-Anisic Acids of 3,6- bis-, belong to benzoic acid
It is herbicide, with uptake and translocation effect, has notable preventive effect to annual and perennial broadleaf weed.Mediben is used for seedling
After spray, medicament can quickly by weeds leaf, stem, root absorb, conducted, focused mostly in separate living tissue up and down by bast
And the vigorous position of metabolic activity, the normal activity of plant hormone is hindered, so that it is dead.Grass is absorbed after medicament
Carry out metabolic breakdown that can be quickly is allowed to fail, therefore the stronger resistance to the action of a drug of performance.
Herba Carpesii macrocephali (Carpesium macrocephalumFranch. Et Sav) for the smart platymiscium of composite family daybreak,
Stem is high 60-140 centimetres, and blade is larger, gradually small upwards, and in width egg shape, ellipse to Long Circle, capitulum, fruit is round shape
It is avette, have capitate trichomes.It is distributed in the ground such as China northeast, North China and Henan, Southern Shaanxi, Gansu, Sichuan.
Cottonsedge-like thistle herb(Cep halanop los setosum Kitam it is) composite family field thistle platymiscium, perennial herb,
It is high 50~100 centimetres.Stem is upright, top branch, by thin hair or wool.Leaf alternate, base portion leaf tool handle, top leaf base embraces stem,
Blade pinnation spinosity.Capitulum is big, single raw or several consor branch ends, close by wool；Phyllary outer layer top has lunge；
Premium color.Achene, pappus pinniform.It is distributed in the ground such as China Sichuan, Yunnan and Tibet.
Current herbicide for paddy field is limited by crop safety, and it is difficult to efficiently control paddy rice that a kind of herbicide, which is used alone,
The generation of field weed, and residues of pesticides also influence people's healthy closely for the harm of this season crop or succession crop.
Botanical pesticide derives from nature.Do not pollute the environment and agricultural product typically, the possibility of accumulation toxicity is not in environment and human body
Greatly, it is comparatively safe to people and livestock, small is injured to pest natural enemy, and insect is difficult to produce antibody to it, with low toxicity, low-residual
The characteristics of, the high-quality of agricultural product can be adhered to, therefore botanical pesticide has wide market.But botanical pesticide, which has, to be seen
The inferior position that effect is slow, price is high, therefore the botanical pesticide of single component has certain difficulty in China's popularization.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of safe and effective Herbicidal combinations, by by traditional chemical weeding
Agent Mediben is answered with plant herbicidal active component Herba Carpesii macrocephali extract and cottonsedge-like thistle herb extract according to a certain amount
Match somebody with somebody, both avoided residues of pesticides, food-safety problem that single use chemical pesticide is brought, botanical pesticide is compensate for again and is taken effect
Slow shortcoming, and acted synergistically between various active composition, activity of weeding can be greatly improved.
The invention provides a kind of Herbicidal combinations, its active component is Mediben, Herba Carpesii macrocephali extract and big thorn
Youngster's dish extract is constituted, and weight ratio is 10-40:100-200:150-300.
The preparation method of the Herba Carpesii macrocephali extract is：Take Herba Carpesii macrocephali complete stool to cross pulverizer crushing, cross 40 mesh
It is placed in after sieve in refluxing extraction kettle, adds the ethanol of its 3 times of quality, be heated to 75-85 DEG C, extract 12h, filtering is concentrated under reduced pressure
Filtrate produces Herba Carpesii macrocephali extract into medicinal extract.The preparation method of the cottonsedge-like thistle herb extract is：Take cottonsedge-like thistle herb complete stool
Pulverizer crushing is crossed, is placed in after crossing 40 mesh sieves in refluxing extraction kettle, adds the methanol of its 3.5 times of weight:Acetone volume ratio is 1:1
Mixed solvent, be heated to 65-75 DEG C, extract 12h, filtering, the filtrate that is concentrated under reduced pressure produces cottonsedge-like thistle herb extract into medicinal extract.
Herbicidal combinations of the present invention can be configured to water together with surfactant, stabilizer, antifreezing agent and solvent
Agent is used.Wherein described surfactant can for APG, tallow amine APEO, neopelex, have
Organic silicon surface active agent, APES etc.；The stabilizer can be malic acid, pyrophosphoric acid, phthalic acid, phosphorus
Sour tributyl etc.；The antifreezing agent can be urea, ethylene glycol, propane diols, glycerine, polyethylene glycol etc.；The solvent can be with
For deionized water, methanol, ethanol, acetone etc..
Herbicidal combinations of the present invention can be applied in rice terrace postemergence weed control, particularly in rice terrace is prevented and kill off
Application in broad leaved weed has remarkable result.
Herbicidal combinations of the present invention have advantages below：
1st, activity of weeding is high.By the combination of chemical pesticide and botanical pesticide, weeds, reduction are killed by different mechanism
Weed Resistance produces speed, drastically increases activity of weeding.
2nd, Weed Resistance is delayed.The Herbicidal combinations of the present invention are ternary built product, reduce weeds and medicament is resisted
Property, the imitation of antagonism weeds is improved, so as to extend the service life of medicament.
3rd, it is safe.The Herbicidal combinations of the present invention, greatly reduce the usage amount of chemical pesticide, so as to making
The harm of thing reduces, environmentally friendly, decreases the residues of pesticides harm healthy to people.
