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.
