Example Embodiment

[0022] Example 1 Indoor virulence determination of prothioconazole and nisin paired with wheat powdery mildew

[0023] Indoor bacteriostatic effect determination method: The growth rate method is used to determine the inhibitory effect of the bactericidal composition on wheat powdery mildew. From the edge of the wheat rot disease colony cultured on the PDA medium for 4 days, take the hyphae blocks with a diameter of 5mm and inoculate them on the PDA medium plates containing different concentrations of fungicides, and cultivate them at a constant temperature at 28℃. In contrast, the colony diameter of each treatment was measured after 4 days, and the percentage of inhibition of the growth of the mycelium was calculated. Through regression analysis of the logarithm of each treatment dose and the probability value of the mycelial growth inhibition rate, calculate the inhibitory concentration of the treated fungicide against wheat powdery mildew (EC s0 ), and then calculate the co-to...

[0033] Example 2 Indoor virulence determination of prothioconazole and nisin paired with wheat sharp eyespot

[0034] Indoor antibacterial effect determination method: the growth rate method is used to determine the inhibitory effect of the bactericidal composition on wheat sharp eyespot. From the edge of the wheat sheath blight colony cultured on the PDA medium for 4 days, take the hyphae blocks with a diameter of 5mm and inoculate them on the PDA medium plates containing different concentrations of fungicides, and cultivate them at a constant temperature at 28℃. In contrast, the colony diameter of each treatment was measured after 4 days, and the percentage of inhibition of the mycelial growth of the agent was calculated. Through regression analysis of the logarithm of each treatment dose and the probability value of the mycelial growth inhibition rate, the inhibitory concentration of the treated fungicide against wheat sheath blight (EC 50 ), and then calculate the co-toxicity...

[0043] Example 3 Indoor virulence determination of prothioconazole and nisin paired with wheat fusarium wilt

[0044] Indoor bacteriostatic effect determination method: The growth rate method is used to determine the inhibitory effect of the bactericidal composition on wheat fusarium wilt. From the edge of the wheat root rot disease colony cultured on the PDA medium for 4 days, take the hyphae blocks with a diameter of 5mm and inoculate them on the PDA medium plates containing different concentrations of fungicides, and cultivate them at a constant temperature at 28℃. In contrast, the colony diameter of each treatment was measured after 4 days, and the percentage of inhibition of the growth of the mycelium was calculated. The logarithm of each treatment dose and the probability value of the mycelial growth inhibition rate were used to perform regression analysis to calculate the inhibitory concentration of the treated fungicide against wheat wilt (EC 50 ), and then calculate the ...

Abstract

The invention discloses a bactericidal composite containing prothioconazole and nisin. The bactericidal composite comprises effective components: prothioconazole and nisin, and the mass ratio of prothioconazole to nisin is 1-80:1-80. The bactericidal composite can be applied to prevention and treatment of bacterial diseases of fruit trees, vegetables and cereal crops, has an obvious synergistic effect, delays the drug resistance of pathogenic bacteria, has a long lasting period, reduces the drug use frequency and dosage, and reduces the use cost. The bactericidal composite can be used for preventing and treating diseases such as wheat powdery mildew, banded sclerotial blight, wilt and leaf spot, and has a remarkable effect.

Description

technical field [0001] The invention relates to the field of agricultural disease prevention and control, in particular to a combined fungicide containing prothioconazole and nisin. Background technique [0002] Prothioconazole, the mechanism of action of prothioconazole is to inhibit the demethylation at the 14th position of lanosterol or 24-methylene dihydromimaudine, the precursor of sterol in fungi, that is, demethylation Inhibitors (DMIs). Not only has good systemic activity, excellent protection, treatment and eradication activity, but also has a long lasting effect. Through a large number of field efficacy tests, the results show that prothioconazole not only has good safety for crops, but also has a good effect on disease prevention and treatment, and has a significant increase in yield. Compared with triazole fungicides, prothioconazole has more Broad-spectrum bactericidal activity. [0003] Prothioconazole is mainly used to prevent and control many diseases of c...
