Gummy Stem Blight is a cucurbit-rot disease caused by the fungal plant pathogen Didymella bryoniae (anamorph Phoma cucurbitacearum). Gummy Stem Blight can affect a host at any stage of growth in its development and affects all parts of the host including leaves, stems and fruits. Symptoms generally consist of circular dark tan lesions that blight the leaf, water soaked leaves, stem cankers, and gummy brown ooze that exudes from cankers, giving it the name Gummy Stem Blight. Gummy Stem Blight reduces yields of edible cucurbits by devastating the vines and leaves and rotting the fruits. There are various methods to control Gummy Stem Blight, including use of treated seed, crop rotation, using preventative fungicides, eradication of diseased material, and deep plowing previous debris.

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.
