Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of complex preparation of jinggangmeisu and bacillus subtilis
And its it prepares and applies.
Background technology
Rice sheath blight disease and false smut are the Major Diseases in Rice Production.Rice sheath blight disease is one kind by miliary damping-off
Rice disease caused by bacterium Rhizctonia solani is one of three major disease of rice, in countries such as South America, Europe And Africas
There is generation with the main rice workspace in China, causes Rice Yield Loss Caused serious.Rice green smut is by ustilaginoidea virens
Rice Panicle fungal disease caused by Ustilaginoidea virens, is distributed widely in Asia, Africa, South America and Europe
Multiple countries of the rice main producing region such as continent, the generation in China aggravate year by year, and false smut not only influences the yield and product of rice
Matter, reduces rice commodity value, and ustilaginoidea virens is also toxic to people and animals.
Currently, the pharmacy variety for preventing banded sclerotial blight and false smut on rice is relatively single and medication is frequent, usage amount be in by
The trend that year rises.Single medicament, which is used for a long time, makes germ develop immunity to drugs, and not only cost accounting increases, and drug effect also can be significantly
It reduces, therefore market needs new medicament to prevent rice sheath blight disease and false smut.

To mixed liquor；
2) it in the mixed liquor for preparing jinggangmeisu, bacillus subtilis input step 1), is uniformly mixed to get compounding
Preparation.
The complex preparation of above-mentioned jinggangmeisu and bacillus subtilis can be used for preventing rice sheath blight disease or false smut.
The design principle of the present invention：Jinggangmeisu is a kind of low-toxin farm chemicals, it is a kind of antibiotic that actinomyces generate,
It, can be thin by thalline quickly after rice sheath blight disease and false smut germ mycelia touch jinggangmeisu with very strong absorbability
Born of the same parents absorb and are conducted in thalline, somatic cells normal growth and development are interfered and inhibit, to play the effect sterilized well
Fruit；Bacillus subtilis is biological agent, and strain is isolated from soil or axis, is generated during thalli growth withered
Lavendustin, polymyxins, nystatin, gramicidins isoreactivity substance, these active materials are to pathogenic bacteria or autogenous infection
Conditioned pathogen have apparent inhibiting effect；Jinggangmeisu and bacillus subtilis are two kinds of heterogeneities and different role
The two is compounded preferable solution germ resistance problems, delays the generation of drug resistance, and well ridge is mould by the fungicide of mechanism
Element and two kinds of ingredients of bacillus subtilis do not have toxic action to natural enemy, can be effectively protected natural enemy, to rice sheath blight disease and
False smut synergistic effect is notable；Compound synergic agent simultaneously, is effectively increased jinggangmeisu and bacillus subtilis in plant surface
Permeability and the surface tension that can reduce aqua dilution reduce contact angle between crop after medicine liquid spray, make liquid
It is easier to be attached to crop leaf surface, will not just be slid when being stained with blade, improve pesticide utilization rate, increase jinggangmeisu
With bacillus subtilis in the conduction in crop；Composite reagent is synergistic apparent, reduces applications of pesticide amount, reduces agriculture
Industry cost.

Jinggangmeisu and bacillus subtilis are configured to the mother liquor of different ratio in table 1 with sterile water dissolution, according to pre-
It does experiment as a result, this 7 processing of A, B, C, D, E, F, G are diluted to 5 mass concentration gradients with sterile water again：2500、
5000,10000,20000,40000 μ g/mL measure compound drug virulence according to mycelial growth rate method.Wherein, withered grass gemma
The use of bacillus subtilis bacterium solution is made in bacillus.
1 jinggangmeisu of table is handled with bacillus subtilis medicament different ratio
3.2 chemicals treatment
Compound drug virulence is measured according to mycelial growth rate method, heating fusing quantitative culture medium 49mL, it is cooled to 50~
1mL reagent agents are added at 55 DEG C, it (is 1 weight of such processing per ware to be poured into after fully shaking up in 4 sterilizes culture dishes
It is multiple).After to be solidified, mark each ware medicament title and concentration (former diluted concentration gradient dilutes 50 times again, i.e., 50,100,200,
400、800μg/mL).The culture medium of control group adds 1mL sterile waters.
With sterile working, rice sheath blight disease with transfer needle take one piece of bacteria cake (bacteria cake diameter 0.5cm) accomplished fluently in advance in
Mixed medicine culture medium flat plate center, is subsequently placed in training in 25 DEG C of biochemical cultivation cases, and right-angled intersection rule measures each processing after 72h
Colony diameter；Rice green smut takes one piece of bacteria cake (bacteria cake diameter 0.5cm) accomplished fluently in advance in mixed medicine culture medium with transfer needle
Tablet center is subsequently placed in training in 28 DEG C of biochemical cultivation cases, and right-angled intersection rule measures each processing colony diameter after 14 days.
3.3 investigation and calculating：
Investigation result calculates mycelial growth inhibition rate of each concentration for the treatment of to fusarium moniliforme by formula (1), (2)：
Bacterium colony increases diameter=colony diameter-bacteria cake diameter ... ... ... ... ... ... ... ... (1)
Mycelial growth inhibition rate (%)=blank control bacterium colony increases diameter-processing bacterium colony and increases diameter) ÷ blank controls
Bacterium colony increases diameter × 100 ... ... ... ... ... ... ... ... ... (2)
4.2 statistical analysis
Make regression analysis according to each drug concentration logarithm and corresponding mycelial growth inhibition rate niqueMin, calculates each medicine
The ED of agent50, ED95Equivalent and its 95% confidence limit.
Co-toxicity coefficient assay method is carried out by Sun Yunpei (1960) method, and the specific method is as follows：
Using A as standard agent, then the theoretical toxicity index of A is 100.
The theoretical toxicity index (TI) of B=(A medicaments ED50÷ B medicaments ED50)×100
(A+B) actual toxicity index (ATI) of mixture=(A medicaments ED50÷ mixtures ED50)×100
(A+B) TI × A medicaments of theoretical toxicity index (TTI)=A medicaments of mixture account for TI × B of mixture %+B medicaments
Medicament accounts for mixture %
(A+B) co-toxicity coefficient of mixture=(ATI ÷ TTI) × 100
Co-toxicity coefficient indicates synergistic effect when being more than 120, summation action is indicated between 80~120, light rain is when 80
For antagonism.
