The present application belongs to the technical field of pesticides, and particularly relates to a fungicide composition for preventing and treating vine gummy stem blight. The fungicide composition for preventing and treating vine gummy stem blight is prepared by compounding thymol with monensin sodium or physcion methyl ether as effective components. The fungicide composition of the present application has different fungicidal mechanisms of thymol, monensin sodium and physcion methyl ether, and the combination of the three components can delay the accumulation and development of pathogenic fungi resistance, and effectively overcome the problems existing in the prevention and treatment of vine gummy stem blight by using single-component pesticides. In addition, the effective components of the fungicide composition of the present application have a synergistic effect on vine gummy stem blight, can improve the prevention and treatment effect on vine gummy stem blight, help to reduce the application dose of the pesticide, and effectively overcome the problems of pesticide residue exceeding the standard and environmental pollution. Furthermore, thymol, monensin sodium and physcion methyl ether in the fungicide composition of the present application are environmentally friendly and green.

This invention discloses a method for preparing type III collagen peptides and their applications. The method for preparing type III collagen peptides effectively avoids the problem of easy degradation of small molecule peptides in microorganisms by expressing sequence monomers in tandem as highly stable macromolecular precursor proteins. Combined with cloning into expression vectors, high-yield expression is achieved. By combining specific enzymatic digestion methods with ultrafiltration and specific enzymatic digestion technology, the high uniformity of the final product sequence and a purity of over 95% are ensured. This method not only completely solves the pathogenic risks and batch instability of animal-derived extraction methods, but also overcomes the high cost and environmental pollution problems of chemical synthesis methods, realizing efficient, safe and controllable production of small molecule type III collagen peptides.
