3, experiment conclusion
Can draw from above-mentioned test: after Fluoxastrobin and cyproconazole are mixed, obviously increase than the inhibition effect of using single agent to apple mildew bacterium and pepper anthracnose bacterium.
II, pot experiment method
Employing is measured embodiment the bactericidal effect of powdery mildew of cucumber.When long the to the 3rd to four true leaf of potted plant cucumber, select behind the mounted blade that growing way is prosperous, growth is used (4 seedlings of every basin field planting) for test uniformly, each handles repetition 8 times.Mentioned reagent is respectively diluted 2000 times, and constant spray medicine connect bacterium after 24 hours routinely, every basin spray bacterium liquid 5ml, insulation (21～24 ℃) (relative moisture) 90% of preserving moisture then) guarantee the invasion of germ.After treating that morbidity is stable, investigate the complete stool disease index, and make evaluating drug effect with blank and single agent contrast according to the powdery mildew of cucumber grade scale.
Statistical analysis technique
1, state of an illness grade scale
0 grade: blade does not have scab
1 grade: lesion area accounts for below 5% of whole blade area;
3 grades: lesion area accounts for 6～10% of whole blade area;
5 grades: lesion area accounts for 11～25% of whole blade area;
7 grades: lesion area accounts for 26～50% of whole blade area;
9 grades: lesion area accounts for more than 50% of whole blade area;
2, computational methods
The total number of sheets * 9 of disease index=∑ (the relative progression of sick number of sheets * at different levels) * 100/ investigation
Control efficiency=(contrast disease index-processing disease index) * 100/ contrast disease index
The different preparations of table 3 are to the data of preventing and treating of powdery mildew of cucumber
Can draw from last table 3, Fluoxastrobin is mixed with cyproconazole has very high synergistic effect to powdery mildew of cucumber than single agent.
