Abstract
The invention relates to vegetative antiseptic, and the raw material contains the following weight-proportioned material medicine: sophora flavescens is 14-15 parts, phellodendron is 0.8-1.2 parts, astragalus is 1.2-1.6 parts, andrographis paniculata is 0.8-1.2 parts, stem of capillary sagebrush is 0.8-1.2 parts, and isatis root is 0.8-1.2 parts. The vegetative antiseptic of the invention is effective, low-toxic, and environment-friendly. The invention also relates to the preparation method and the application of the vegetative antiseptic.
Description
Technical field
The present invention relates to a kind of bactericide, particularly a kind of bactericide that contains matrine and its production and application.
Background technology
Along with the raising and the science and technology development of China's living standards of the people, people have had higher level requirement to clothing, food, lodging and transportion--basic necessities of life, particularly food security have been had higher requirement.That people more and more favor is pollution-free, the green cereal and the vegetables and fruits of non agricultural chemical residuum.But China has caused destruction in various degree owing to all be high poison, the persistent pesticide of chemosynthesis preventing and treating what use aspect the disease for a long time to ecotope, and the food that people and animals are depended on for existence has also caused serious day by day harm.
Have agriculture available water logging kuh-seng liquid of data record and decocting kuh-seng liquid to prevent and treat the vegetable melon and fruit disease, preventive effect is good, and can reduce environment damage.But this class reagent combination is too simple, and effect is comprehensive inadequately, and the preparation method also is not suitable for producing in batches.
Therefore, a kind of novel bactericide need be proposed on this basis, make its comprehensively, effectively can be to not prevented and treated plant and environment pollutes in the sterilization, and be fit to industrialized mass production more.
Summary of the invention
The objective of the invention is to: a kind of novel bactericide is provided, makes it not only have good sterilizing disease-preventing effect but also environmentally friendly, plant noresidue.
The objective of the invention is to be achieved through the following technical solutions:
A kind of bactericide is provided, contains following bulk drugs in its raw material:
0.8～1.2 part of 14～15 parts of kuh-sengs, 0.8～1.2 part of golden cypress, 1.2～1.6 parts of the Radixs Astragali, 0.8～1.2 part of Herba Andrographitis, 0.8～1.2 part of oriental wormwood and Radix Isatidis.
The formulation that described bactericide can be prepared into is a missible oil.
The raw material of described bactericide emulsifiable concentrate is made up of 75～85% bulk drug and 15～25% auxiliary agent; Wherein, bulk drug is: 0.8～1.2 part of 14～15 parts of kuh-sengs, 0.8～1.2 part of golden cypress, 1.2～1.6 parts of the Radixs Astragali, 0.8～1.2 part of Herba Andrographitis, 0.8～1.2 part of oriental wormwood and Radix Isatidis.
The raw material of described bactericide emulsifiable concentrate preferably is made up of 80% bulk drug and 20% auxiliary agent; Wherein, bulk drug is preferably: 1 part of 14.45 parts of kuh-sengs, 1 part of golden cypress, 1.5 parts of the Radixs Astragali, 1 part of Herba Andrographitis, 1 part of oriental wormwood and Radix Isatidis.
Described selection of auxiliary permeable synergistic auxiliary agent, No. 9, preferred commercially available capital.
The present invention also provides the preparation method of described bactericide, may further comprise the steps:
1) get according to described weight portion and mix behind the bulk drug and be ground into powder, standby;
2) solvent that adds its 10 times of weights in step 1) gained mixed-powder is used to extract bulk drug active ingredient, feeds the steam distillation solvent then soup is concentrated, and so the concentrated medicament 6～8 hours while extracting makes and carries to such an extent that relative density of medicine liquid is 1.1～1.2;
3) in step 2) add auxiliary agent according to described percentage by weight in the gained concentrated medicament, fully stirring promptly obtains the emulsifiable concentrate of described bactericide.
The described pulverizing of step 1) is the meal that pulverizing medicinal materials was become 30～40 mesh sieves.
Step 2) described solvent preferred concentration is 95% food grade ethanol.
The present invention also provides the application of described bactericide aspect the common disease of control fruit, wheat, paddy rice, vegetables.The disease of concrete control comprises: the scab of apple, pears, peach, anthracnose, brown spot, ring spot; Wheat powdery mildew, rust; Rice blast; The powdery mildew of grape, watermelon, downy mildew, anthracnose; The powdery mildew of capsicum, vegetables, upright withered, downy mildew, anthracnose etc.
Contain matrine in the kuh-seng among the side of the present invention, belong to thick croak piperidine derivatives class, have the effect of sterilization.The present invention with the main active ingredient of matrine as bactericide, is aided with the alkaloid and the volatile oil that have biocidal efficacies in other raw materials just again, has realized the effective control to plant disease.
The preferred application process of bactericide of the present invention: bactericide of the present invention use with the prevention crop pest be main purpose, the bactericide for preparing is diluted 600～800 times, application dosage according to different diseases kind and the definite unit are of plant size is generally every mu and uses 0.3～0.4g bactericide of the present invention.
Bactericide of the present invention is remarkable to the common disease-controlling effect of above-mentioned fruit, wheat, paddy rice and vegetables, is example with bactericidal agent for preventing and treating cucumber downy mildew of the present invention below, and the effect of controlling plant diseases of the present invention is described:
One, experimental subjects:
Tianjin spring No. 4 cucumber downy mildews
Two, experimental technique:
Experiment place: farmland, Tang Zhuan village, the Baoding city Wu Hua of Qingyuan County township.
Experiment grouping: select 20 sub-districts at random in the field, every sub-district area 14m
2These 20 sub-districts are divided into 5 groups at random, one group of 4 sub-district, every group of bactericide 0.18g/ mu (A), 0.24g/ mu (B), 0.36g/ mu (C), 85% epidemic disease frost clever wetting powder 102g/ mu (D) and clear water (E) of using the embodiment of the invention 1 preparation respectively, dispenser when the field begins to fall ill, sprayed once every 7 days, execute altogether 4 times, each organizes with till spraying under the medicine blade medicine liquid droplet spray value according to design concentration.
The experiment observational technique: investigated in 7 days after the last dispenser, 100 leaves of investigation in every sub-district divide the Pyatyi record incidence of disease and sick level, and calculate every group 4 sub-district disease indexs (disease refers to) and control efficiency average.Control efficiency is calculated according to following formula:
Three, experimental result
Experimental result sees Table 1.
The effect mean value of table 1. bactericide control of the present invention cucumber downy mildew
| Handle | Disease refers to | Preventive effect % |
| A B C D E | 12.3 10.7 5.82 7.34 27.1 | 54.6 60.6 78.5 73.2 |
As seen, bactericide of the present invention has favorable effect to cucumber downy mildew from table 1, and when particularly using with the amount of application of 0.36g/ mu, its preventive effect significantly is better than and presses down the frost spirit.
In addition, compared with prior art, bactericide of the present invention also has following other beneficial effect:
1. bactericide of the present invention is safer to people and animals.
By the SD rat is carried out fragmentation test, the result shows bactericide of the present invention to eyes, skin nonirritant, and bright its acute toxicity of per os skin test checking is a low toxicity, easily decomposes in atmosphere and soil, and non-poisonous material is residual.
2. bactericide of the present invention is little to the influence of farmland natural enemy, helps to keep ecotope.
3. bactericide of the present invention with the traditional Chinese medicine is feedstock production, and is more friendly to environment than the bactericide of chemistry property.
