Test example is 1.: pyraclostrobin and bromothalonil compounded are to the effect of cucumber downy mildew:
Pot-culture method is adopted in test, measures pyraclostrobin, bromothalonil and its composition to the control efficiency of cucumber downy mildew.
Choose three to four consistent leaf phase cucumber seedlings of growing way, every kind of test medicine selects 5 basins for the examination cucumber seedling, sprays the about 5mL of every basin under 50PSI pressure with the Potter spray tower.Every kind of test medicine arranges 5 concentration gradients.24h connects bacterium after the chemicals treatment, the sick leaf of the cucumber downy mildew that picks up from the field is evenly shaken off conidium inoculate above cucumber seedling, then cucumber seedling is put into the greenhouse and cultivates.Behind the 7d, according to the morbidity standard complete stool investigation disease index of cucumber downy mildew, and calculate control efficiency, then calculate concentration EC in the inhibition with method of least squares
50, calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun again.
When CTC≤80, then the composition performance is for antagonism, and when 80<CTC<120, then the composition performance is for summation action, and when CTC 〉=120, then the composition performance is synergistic effect.
Actual measurement toxicity index (ATI)=(standard medicament EC
50/ reagent agent EC
50) * 100;
The percentage composition of bromothalonil in the percentage composition of pyraclostrobin+bromothalonil medicament toxicity index * mixture in theoretical toxicity index (TTI)=pyraclostrobin medicament toxicity index * mixture;
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture] * 100;
Table 1 different disposal is to the Toxicity Determination result of bacterium of downy mildew of cucumber
As shown in Table 1, pyraclostrobin and bromothalonil have obvious synergistic effect between proportioning 1: 50~50: 1, and especially between 1: 25~25: 1, synergistic effect is more obvious, and co-toxicity coefficient is more than 220.
Test example is 2.: pyraclostrobin and bromothalonil compounded are to the effect of downy mildew of garpe:
In the toxic dielectric method of indoor employing, measure combination sterilization composition 60% water dispersible granules of the present invention and 25% pyraclostrobin missible oil, 25% bromothalonil missible oil to the fungistatic effect of downy mildew of garpe.
Test method: in the PDA medium, add respectively quantitative above-mentioned three kinds of medicaments (establishing not dosing blank), inoculation downy mildew of garpe fungi strain after the cooling, cultivate 24 ℃ of unglazed photographs under the condition after the inoculation, after cultivating 120 hours, carry out result's investigation.Test result is as follows:
Table 2 different disposal is to the indoor Antibacterial Activity result of Plasmopara viticola
As shown in Table 2, the present invention's combination sterilization composition of containing pyraclostrobin and bromothalonil is significantly higher than the activity of two kinds of single doses to the bacteriostatic activity of downy mildew of garpe.
