Abstract

The present invention relates to a wheat powdery mildew control medicament which is prepared by weighing rhubarb, Chinese prickly ash, radix euphorbiae lantu, Sculellaria barbata, cortex phellodendri, dandelion, euphorbia humifusa and Chinese yam, crushing, blending, soaking in ethanol, shaking for extraction, after centrifugation, rotatably evaporating a supernatant to obtain paste, diluting the paste with water, and adding potassium dihydrogen phosphate and 15% triadimefon to prepare a finished product. Active ingredients of the components are extracted and mxied with the potassium dihydrogen phosphate and the triadimefon, the amount of the triadimefon is reduced, the wheat powdery mildew control medicament is sprayed directly to wheat fields, the treatment effect is good, the cure rate is over 97%, and the wheat powdery mildew control medicament has good growth-promoting effect on cured plants, and can reduce the impact of large-scale production reduction.

Description

A kind of wheat powdery mildew pesticide control and preparation method thereof

Technical field

The invention belongs to wheat powdery mildew Prevention Technique field, especially a kind of wheat powdery mildew pesticide control preparation method.

Background technology

Semen Tritici aestivi is the grass of a kind of extensively plantation all over the world, and its caryopsis is one of mankind's main food, can be made into the foods such as bread, steamed bread, cookies, cake, new year cake, it may also be used for fermentation beer, ethanol etc. after wearing into flour. wheat planting process can be subject to the threat of multiple diseases, powdery mildew therein is a kind of worldwide disease, at China coast, Sichuan, Yunnan, Guizhou occurs general, harm also weighs, northeast in recent years, North China, northwest Mai Qu also has the gesture being on the rise, this disease can encroach on each organ of wheat plant overground part, but based on blade and sheath, during morbidity weight, Ying's shell and awns also can be injured, pathogenic bacterium borrow air-flow to propagate on wheat leaf blade by conidium or ascus steamed bun, when running into the suitable environment of temperature and humidity conditions, start morbidity, pandemic time serious, cause the underproduction, have a strong impact on yield, triazolone cream can be used during preventing and treating, lucky star cream, carbendazim, the medicines such as Difenoconazole, growth along with the time of use, consumption is increasing, surrounding enviroment are had a strong impact on.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, it is provided that free from extraneous odour, noresidue, a kind of wheat powdery mildew pesticide control that prevention effect is good.

The present invention adopts the technical scheme that:

A kind of wheat powdery mildew pesticide control, it is characterised in that: include the following components mixed by weight:

And, the following components including mixing by weight:

The preparation method that it is a further object to provide a kind of wheat powdery mildew pesticide control, it is characterised in that: comprise the following steps:

(1) weigh Radix Et Rhizoma Rhei, Pericarpium Zanthoxyli, the Radix Euphorbiae Fischerianae (Radix Euphorbiae Ebracteolatae), Herba Scutellariae Barbatae, Cortex Phellodendri, Herba Taraxaci, Radix seu Caulis Parthenocissi tricuspidatae, Rhizoma Dioscoreae by metering, dry after cleaning;

(2) each component is pulverized, and then mutually blends, and puts in the ethanol of 80% and soak 2 hours after stirring;

(3) shaken at room temperature extracts 12 hours, after standing 1 hour, continues mechanical shaking extraction 3 hours;

(4) taking supernatant after centrifugal for step product (3), the mastic after rotary evaporation adds 200 times of sterilized water dilutions;

(5) continuously add potassium dihydrogen phosphate and 15% triadimefon, after stirring, prepare finished product.

Advantages of the present invention and having the benefit effect that

In the present invention, Radix Et Rhizoma Rhei, Pericarpium Zanthoxyli, the Radix Euphorbiae Fischerianae (Radix Euphorbiae Ebracteolatae), Herba Scutellariae Barbatae, Cortex Phellodendri, Herba Taraxaci, Radix seu Caulis Parthenocissi tricuspidatae, Rhizoma Dioscoreae is weighed by metering, blend after pulverizing, put in ethanol and soak, then mechanical shaking extraction, supernatant rotary evaporation after centrifugal, the mastic dilute with water obtained, adds potassium dihydrogen phosphate and 15% triadimefon prepares finished product. The effective ingredient of each component is extracted and potassium dihydrogen phosphate and triadimefon immixture, reduces the consumption of triadimefon, is directly sprayed in wheatland, therapeutic effect is good, cure rate reaches more than 97%, and the growth promoting function after recovering for plant is good, reduces the impact dropped in production over a large area.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, it is impossible to limits protection scope of the present invention with following embodiment.

A kind of wheat powdery mildew pesticide control, it is a feature of the present invention that: include the following components mixed by weight:

Preferred scheme is: include the following components mixed by weight:

(2) each component is pulverized, and then mutually blends, and puts in the ethanol of 80% and soak 2 hours after stirring;

(3) shaken at room temperature extracts 12 hours, after standing 1 hour, continues mechanical shaking extraction 3 hours;

(4) taking supernatant after centrifugal for step product (3), the mastic after rotary evaporation adds 200 times of sterilized water dilutions;

(5) continuously add potassium dihydrogen phosphate and 15% triadimefon, after stirring, prepare finished product.

In the present invention, Radix Et Rhizoma Rhei, Pericarpium Zanthoxyli, the Radix Euphorbiae Fischerianae (Radix Euphorbiae Ebracteolatae), Herba Scutellariae Barbatae, Cortex Phellodendri, Herba Taraxaci, Radix seu Caulis Parthenocissi tricuspidatae, Rhizoma Dioscoreae is weighed by metering, blend after pulverizing, put in ethanol and soak, then mechanical shaking extraction, supernatant rotary evaporation after centrifugal, the mastic dilute with water obtained, adds potassium dihydrogen phosphate and 15% triadimefon prepares finished product. The effective ingredient of each component is extracted and potassium dihydrogen phosphate and triadimefon immixture, reduces the consumption of triadimefon, is directly sprayed in wheatland, therapeutic effect is good, cure rate reaches more than 97%, and the growth promoting function after recovering for plant is good, reduces the impact dropped in production over a large area.
