Requirement.
Bacillus subtilis is a kind of new microbial source biological pesticide.Nutrition and space can be formed with other harmful bacterias
The competition in site, the surfactin with antibacterial, the effect of antiviral and biosurfactant can be produced.Withered grass gemma
Secondary metabolites caused by bacillus is harmful to pathogen archespore wall to other and produces dissolution, makes the cell of harmful levels of pathogens
Wall perforation, deformity etc..In addition, bacillus subtilis is as microorganism mushroom, additionally it is possible to promotes plant growth.
Ethiprole is a kind of Phenylpyrazole insecticides, and can be not only used for seed treatment can carry out foliar spray, insecticidal spectrum again
Extensively, to insect based on stomach poison function, have concurrently and tag and certain systemic action, it, which imposes on soil, can effectively prevent and treat corn root leaf
First, wireworm and cutworm.
Bacillus subtilis and ethiprole compatibility do seed treatment, and both mutually cooperate with, can be simultaneously from two differences
Target acted on, comprehensive protection is provided for seed, its Environmental compatibility is good, and toxicity is low, to biologies such as people's storage, natural enemies
Safety, belong to the biological seed inorganic agent of broad-spectrum high efficacy.The seed treatment can be made into Waterless Seed Dressing agent, suspension seed-coating agent, pass through
Seed dressing or seed pelleting, for preventing and treating the subterranean pest-insects such as the crop such as corn, wheat, rice grub, wireworm, mole cricket；Simultaneously
The multiple diseases such as the droop of crop, banded sclerotial blight, full rot, rice blast, gray mold, powdery mildew, bacterial wilt can be played anti-
Control effect.

Measure ratio respectively 5.1：0.4、5.05:0.45、5.0:0.5、4.95:0.55、4.9:0.6.
（2）Plating determination experiment
Each experimental pharmacy is proceeded as follows respectively：1mL test medicines are taken, are added to 45 DEG C or so, 49mL quantitatively trains
Support and poured into after being shaken up in base in culture dish, cooling is standby.By cultured pathogen, aseptically going out with diameter 5mm
Bacterium card punch steals bacteria cake from colony edge, and with inoculator by pure culture biscuits involvng inoculation in flat board center, mycelia is face-up, covers culture
Ware, in 25 DEG C of dark culturing 4d.Each medicament carries out 4 groups of parallel tests simultaneously, and adds culture medium with the 0.1% Tween 80 aqueous solution
As blank control.
（3）Investigation and statistical analysis
Investigation is measured at control group colony growth to culture dish edge.
Colony diameter is measured using crossing method, bacteriostasis rate is calculated, pharmacy test concentration and bacteriostasis rate is carried out respectively
Logarithm and niqueMin conversion, using log concentration value as independent variable, bacteriostasis rate niqueMin is dependent variable, carries out regression analysis, obtains
Virulence regression equation, EC50And EC90Coefficient correlation and coefficient of synergism, the data obtained are as shown in table 1.
Bactericide is killed according to the virulence size of these data evaluation bacillus subtilis Rhizoctonia solanis and ethiprole
The influence of bacterium effect.
1.2 desinsection（Grub）Determination of activity
（1）Test preparation medicament
Ethiprole is distributed in the 0.1% Tween 80 aqueous solution, prepares one group of ethiprole single dose：If 6 concentration gradients,
Respectively 5,10,20,40,80,160mg/L.
By ethiprole, bacillus subtilis starter medicine（1000000000000 spores/g）It is distributed in the 0.1% Tween 80 aqueous solution, prepares
5 groups of ethiproles and bacillus subtilis intermixture：If 6 concentration gradients, the concentration of wherein ethiprole is respectively 5,10,20,40,
80、160mg/L；The weight ratio of each group ethiprole and bacillus subtilis starter medicine is respectively：5.1:0.4、5.05:0.45、5.0:
0.5、4.95:0.55、4.9:0.6。
（2）Grub test method
Determined respectively to each test medicine above to the virulence of grub using pesticide-clay mixture method：Dry ground earth is crossed into 20 mesh testing sieves,
Then 800g is taken to be fitted into circular culture box（High 10cm, diameter 13cm）, take 100ml test medicines to pour into wherein, Indoor Natural
Mixed uniformly after infiltration 2h, then the wheat seed that imbibition is showed money or valuables one carries unintentionally is mixed into wherein；Select 15 more consistent grubs of size and be put into box
It is interior, allow it voluntarily to bury（What can not voluntarily be buried will be changed）, it is then placed in 26 DEG C of recovery room, knot is checked after 48h
Fruit.Each test medicine carries out 4 groups of parallel tests simultaneously, and is mixed into soil and is used as blank pair by the use of the 0.1% Tween 80 aqueous solution
According to.
（3）Investigation and statistical analysis
Substantially shunk with polypide during inspection result and be unable to scrambler and be considered as death.
The death rate is calculated, the death rate is corrected with Abbott formula, then using log concentration value as independent variable, school
The niqueMin of the positive death rate is dependent variable, asks the virulence regression equation, LC50, LC90, coefficient correlation of each single dose and complex preparation
And coefficient of synergism, the data obtained are shown in Table 2.
Virulence size by these data evaluation ethiproles to grub, analysis bacillus subtilis are big to ethiprole virulence
Small influence, determine the optimum proportioning of bacillus subtilis and ethiprole.
The experimental data of Tables 1 and 2 shows that ethiprole has certain facilitation to bacillus subtilis activity, withered
Careless bacillus also shows that certain synergistic effect to the insecticidal activity of ethiprole, the two reasonable compatibility, can simultaneously reach and kill
The effect of worm diseases prevention.
The ethiprole of table 1 and bacillus subtilis compound sterilizing synergy situation
The ethiprole of table 2 and bacillus subtilis compounding control of grubs synergy situation
2nd, field experiment
2010, Shandong Linqing experimental plot, the seed treatment to the present invention carry out wheat seed dressing and coating is tested, as a result
It is shown in Table 3；2011, Potou experimental plot, wheat seed dressing is carried out to the seed treatment of the present invention and coating is tested, result of the test
It is shown in Table 4.
The experimental data of table 3 and table 4 shows that seed treatment of the invention has the characteristics that：
1st, by crop seed coating or Dressing, to corn, the banded sclerotial blight of wheat, droop, full rot, root-rot
The multiple diseases such as disease, smut, there is preferable preventive effect to subterranean pest-insect.
2nd, the invasion that seed is dressed seed or after being coated seed can be made effectively to avoid pest and disease damage, field lasting period length have synergy
Effect.
3rd, said preparation effective ingredient ethiprole, bacillus subtilis, the two compatibility is safe, has production-increasing function, right
Environment compatibility is good.
4th, ethiprole of the invention and bacillus subtilis complex biological seed treatment are by dressing seed or being coated to seed
Comprehensive protection is provided, meets the developing direction of seed standardized production, there is larger society and economic value.The present invention's
Seed treatment not only facilitates the free of contamination Pesticidal products of production, while can also keep balance and the life of Agro-ecological System
Thing variation, is more beneficial for agricultural sustainable development.
