9 embodiment of table, 26~32 each component and parts by weight
The embodiment of the present invention is the method being combined using Toxicity Determination and field trial.First pass through indoor virulence
Measure, clear two kinds of medicaments compound by a certain percentage after synergy ratio (SR), SR ＜ 0.5 are antagonism, 0.5≤SR≤
1.5 be summation action, and SR ＞ 1.5 are synergistic effect, on this basis, then carry out field trial.
Test method：After prerun determines the effective inhibition concentration range of each medicament, medicament is set respectively by active constituent content
5 dosage processing, if clear water compares.Reference《Farm-chemical indoor determination test rule fungicide》It carries out, is grown using mycelia
Performance rate method measures virulence of the medicament to crop germ.Colony diameter is measured with crossing method after 72h, it is net raw to calculate each processing
Long amount, mycelial growth inhibition rate.Net growth (mm)=measurement colony diameter -5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm (x), with most
Small square law acquires virulence regression equation (y=a+bx), and thus calculates the EC of each medicament50Value.Simultaneously according to Wadley
Method calculates two medicament different ratio synergy ratios (SR), and SR ＜ 0.5 are antagonism, and 0.5≤SR≤1.5 are to be added to make
With SR ＞ 1.5 are synergistic effect.Calculation formula is as follows：
Wherein：A, b is respectively copper 8-hydroxyquinolinate and thiophanate-methyl ratio shared in combination；
A is copper 8-hydroxyquinolinate；
B is selected from thiophanate-methyl.
Application Example two：
For trying disease：Apple tree canker；Test medicine is provided by applicant.
Experimental design：Copper 8-hydroxyquinolinate and thiophanate methyl raw pesticide and the two different ratio mixture are determined by pilot study
Effective inhibition concentration range.
Toxicity test result

Dispenser 3 days after dispenser, investigates disease indexes and calculates preventive effect for 10 days, 20 days.Test result is as follows：
16 copper 8-hydroxyquinolinate of table and thiophanate-methyl and its compounding prevention soybean rust test of pesticide effectiveness
As can be seen from Table 16, soybean rust can be effectively prevented after copper 8-hydroxyquinolinate and thiophanate-methyl compounding, it is found through experiment that
Soybean powdery mildew can also be effectively prevented after copper 8-hydroxyquinolinate and thiophanate-methyl compounding, control effect is above 96%, is better than single dose
Preventive effect, and preventive effect phase is long.It has no adverse effects to target crop in experiment scope of medication.
The experiment by different places throughout the country obtains afterwards, to a variety of works after copper 8-hydroxyquinolinate and thiophanate-methyl compounding
Spot defoliation, rust, epidemic disease, bacterial wilt, ring spot, late blight, downy mildew, anthrachose of grape, powdery mildew, anthracnose on object,
The preventive effect of the Common Diseases such as droop, gray mold, sclerotiniose, rot disease, rice blast, banded sclerotial blight is 96% or more, better than single
Agent preventive effect, synergistic effect are apparent.
