5the suspension of individual spore/milliliter, for subsequent use.Often process 3 basins, repeat for 4 times, and establish the process only containing solvent and surfactant not containing active ingredient to make blank.After spore suspension inoculation 24h, liquid is evenly sprayed in blade face to all wetting, after liquid natural air drying, move to thermostatic chamber, cultivate 7 days ~ 10 days under the condition of temperature 20 ~ 24 DEG C.When the sick leaf rate of blank reaches more than 80%, classification investigation manages incidence everywhere, and often process and at least investigate 30 leaves, grade scale is:
0 grade: anosis;
1 grade: lesion area accounts for less than 5% of one-piece blade area;
3 grades: lesion area accounts for 6% ~ 15% of one-piece blade area;
5 grades: lesion area accounts for 16% ~ 25% of one-piece blade area;
7 grades: lesion area accounts for 26% ~ 50% of one-piece blade area;
9 grades: lesion area accounts for 50% ~ 75% of one-piece blade area;
11 grades: lesion area accounts for more than 75% of one-piece blade area.
Computational methods:
Disease index=[∑ (the sick number of sheets × relative level numerical value at different levels)/(investigation total leaf number × 11)] × 100
Control efficiency (%)=[(contrast disease index-process disease index)/contrast disease index] × 100
By the linear regression analysis between the probit value of preventive effect and the logarithm value of series concentration, obtain the EC of each medicament
50value, calculates the co-toxicity coefficient (CTC) of mixture, evaluates the activity of reagent agent to germ with this by the abundant method of Sun Yun.Co-toxicity coefficient (CTC) >=120, shows as synergistic effect; Co-toxicity coefficient (CTC)≤80, shows as antagonism; 80 < co-toxicity coefficient (CTC) < 120, show as summation action.
