Beneficial effect of the present invention is: tetraconazole and Fungicidal active substance B are composite, show good synergistic effect in certain ratio range, compare with single dose, can reach synergy, the double purpose of controlling, overcoming or delay the germ resistance development and reduce drug cost, thereby improve bactericidal effect, enlarge fungicidal spectrum, reduce the medicament usage amount, when reducing peasant's drug cost, reduced influence degree, i.e. efficiently environmental protection again; Two kinds of active substance structures in composition differ larger in addition, do not have cross resistance, are mixed to use the resistance that can more effectively delay single dose to occur and development, extend service life and the update cycle of single dose.
Employing contains toxic medium method and measures the mixture of tetraconazole and mancozeb, zineb, tmtd, the different proportionings of Propineb to the indoor virulence of peanut Cercospora bacteria.Namely add respectively the reagent agent for preparing by a certain percentage in the PDA sterilising medium, cooling rear inoculation peanut Cercospora bacteria, with the sterilising medium that adds the equivalent coordinative solvent as blank, putting into 27 ℃ of constant incubators cultivated after 3-8 days, adopt the right-angled intersection method to measure colony diameter, calculate bacteriostasis rate, EC
50, the relevant parameter such as CTC, adopt the abundant method of Sun Yun to calculate co-toxicity coefficient (CTC) and estimate mixed effect, the CTC value has synergistic effect greater than 120 o'clock mixtures, less than 80 o'clock be antagonism, have summation action in the time of between 80～120.Relevant calculating formulas is as follows:
Pure amount of growth=bacterium colony average diameter-bacterium cake diameter (0.4cm)
Bacteriostasis rate=[the pure amount of growth of (contrast pure amount of growth-process pure amount of growth) * 100/ contrast] * 100%
The EC50*100 of the EC50/B agent of toxicity index TI (B)=standard agent A
The EC50*100 of the EC50/AB of actual toxicity index ATI (AB)=A
Theoretical toxicity index TTI (AB)=percentage+TI (B) the * B percentage in mixture of TI (A) * A in mixture
Co-toxicity coefficient CTC=ATI (AB)/TTI (AB) * 100
Experimental result is as follows:
Table 1 tetraconazole and the mancozeb list mixture toxicity test to peanut Cercospora bacteria
As seen from the above table, tetraconazole and mancozeb are composite, peanut Cercospora bacteria had good indoor virulence, the CTC value of seven proportionings is all over 120, show that these two bactericide have synergistic function preferably under this proportioning, and mixed ratio synergy between 1:1～1:40 is remarkable.
When tetraconazole and zineb, tmtd, Propineb carry out combine experiment with aforementioned proportion, show the antibacterial rule identical with mancozeb, the synergistic effect to peanut Cercospora bacteria under the ratio of 1:1～1:40 is comparatively obvious.
Measure single, the mixture of tetraconazole and the phonetic phenol of second, bupirimate, carbendazim, thiophanate-methyl to the indoor virulence of powdery mildew of cucumber bacterium at indoor employing seedling pot-culture method.Namely at the greenhouse pot culture cucumber seedling to the 2-3 leaf phase, carrying out foliar spray by the designer drug agent dose processes, inoculation test pathogen after 24 hours, and moisturizing is cultivated in incubator, investigation result when the blank of not dispenser is fully fallen ill, disease scale, preventive effect computational methods are all with reference to the People's Republic of China (PRC) [pesticide field efficacy medicine test criterion].Carry out statistical analysis with the DPS data processing software, calculate the EC50 of each medicament, adopt the abundant method of Sun Yun to calculate co-toxicity coefficient (CTC) and estimate mixed effect.
Result of the test is as follows:
