Embodiment
In order that the objects, technical solutions and advantages of the present invention are more concise, present invention specific examples below
Illustrate, but the present invention is only limitted to absolutely not these embodiments.As described below is only the present invention preferably embodiment, is used only for
The description present invention, it is impossible to be interpreted as limiting the scope of the present invention.It should be pointed out that all in the spirit and principles in the present invention
Within any modifications, equivalent substitutions and improvements for being done etc., all should include within protection scope of the present invention.Therefore, originally
The protection domain of patent of invention should be determined by the appended claims.
Different types of pesticide active ingredient is compounded, is current to solve during agricultural chemicals single dose use cost and anti-
The effective measures of the problems such as property.After different types of pesticide active ingredient mixing, three kinds of type of action are typically exhibited, i.e.,
Summation action, synergistic effect and antagonism.But it is specially which kind of effect, only can be just known by substantial amounts of bioassay test
Road.
The present composition have to cucumber downy mildew and the late blight of potato it is obvious coordinate synergistic effect, can from
It is clearly seen that in the result of lower virulence determination test.
Assays Example 1：Benziothiazolinone is determined with azoles mepanipyrim to the synergy of cucumber downy mildew.
Experiment uses spray-on process dispenser (having water membrane to be advisable with blade surface), is sprayed within 11st in September in 2016
Processing, spray apparatus uses hand sprayer (liquid capacity about 2.0L), every 7 days sprays once, continuously spray 2 times.
Investigation method：
0 grade：Disease-free spot；
1 grade：Lesion area accounts for less than the 5% of whole leaf area；
3 grades：Lesion area accounts for the 6%-15% of whole leaf area；
5 grades：Lesion area accounts for the 16%-25% of whole leaf area；
7 grades：Lesion area accounts for the 26%-50% of whole leaf area；
9 grades：Lesion area accounts for more than the 50% of whole leaf area.
According to survey data, the disease index and prevention effect of each processing are calculated.
Disease index is calculated by formula, and result of calculation retains 2 significant digits：
When carrying out drug combination toxicity test, this experiment calculates the coefficient of synergism (SR) of mixture using Wadley methods, evaluates
The synergy type of mixture.
Wadley methods：The synergistic effect of pharmacy mix, i.e. SR are evaluated according to coefficient of synergism (SR)<0.5 is antagonism,
0.5≤SR≤1.5 are summation action, SR>1.5 be synergistic function.Coefficient of synergism (SR) is calculated by formula (1), (2)：
In formula：
X1--- mixtures EC50Theoretical value, unit is milligrams per liter (mg/L)；
PA--- A percentage composition in mixture, unit is percentage (%)；
PB--- B percentage composition in mixture, unit is percentage (%)；
A EC in A--- mixtures50Value, unit is milligrams per liter (mg/L)；
B EC in B--- mixtures50Value, unit is milligrams per liter (mg/L).
In formula：
The coefficient of synergism of SR--- mixtures；
The EC of X1--- mixtures50Theoretical value, unit is milligrams per liter (mg/L)；
The EC of X2--- mixtures50Measured value, unit is milligrams per liter (mg/L).
The benziothiazolinone of table 1 is determined with azoles mepanipyrim to the synergy of cucumber downy mildew germ
As can be seen from Table 1, benziothiazolinone and azoles mepanipyrim are 1：30~30：Compounded in the range of 1, to cucumber downy mildew disease
Bacterium shows as synergistic effect.
Assays Example 2：Benziothiazolinone compounds the Toxicity Determination to late blight of potato germ with azoles mepanipyrim.
Standard method NY/T1156.2-2006 is surveyed with reference to raw, using pastille culture medium method：Take each single dose and mixture series dense
The decoction 6mL of degree, addition is cooled in 45 DEG C of 54mL PDA culture medium, and the pastille culture medium of final concentration is put down required for being made
Plate.Then the object bacteria colony edge from culture 7 days produces 6mm diameter mycelia blocks, moves in each serial pastille culture medium, mycelia
Down, each 4 repetitions of processing.It is disposed, is placed in 25 ± 1 DEG C of constant temperature biochemical cultivation case and cultivates.
Culture medium flat plate is taken out after 3 days, each processing colony diameter is measured with crossing method, the mycelia life of each processing is calculated
Long inhibiting rate.It is independent variable x according to the logarithm value of drug concentration (mg/L), using the probit value of corrected mortality as dependent variable y, point
Virulence regression equation is not set up, the EC of single dose and each proportioning mixture is calculated using DPS softwares50And its mixture co-toxicity coefficient.Altogether
Malicious coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficients
(CTC) ＜ 120 shows as summation action.Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100。
Theoretical toxicity index (TTI)=(A percentage composition in A toxicity index × mixture)+(the hundred of B in B toxicity index × mixture
Divide content).Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
The benziothiazolinone of table 2 and indoor joint toxicity measuring result of the azoles mepanipyrim to late blight of potato germ
As can be seen from Table 2, benziothiazolinone and azoles mepanipyrim are 1：30~30：Compounded in the range of 1, to the late blight of potato
Germ shows as synergistic effect.
