  • 摘要:The Colletotrichur musae and Fusarium semitectum Berk, Which often occur in banana afterharvest were used as the targets. Three components with antibacterial activity extracted from the leaves ofthe plant were used as "fungicide". The antibacterial effect of the three component substances on thepathogens of anthracnose and shaft rot was studied. The results showed that the inhibitory rates of thecomponents A, B and C at 2 mg/ ml on the pathogens of banana anthracnose and shaft rot reached 82.53%,79.91%, 78.30% and 82 2%, 78.69% and 81.17% respectively. The Ecoo values of component A, B and Cfor banana anthracnose pathogens were 1.70, 185, and 1.69 mg 1 ml. Respectively, the EC90 values forbanana shaft rot pathogens were 1.37, 1.38, and 1.64 mg 1 ml. The antibacterial effect of the threecomponent substances on the pathogen of banana shaft rot was better than that of anthracnose. The threecomponent substances have great potential for controlling post-harvest anthracnose and shaft rot of bananas.

The EC90 values of component A, B and C for banana anthracnose pathogens were 1.70, 1.85, and 1.69 mg / ml. Respectively, the EC90 values for banana shaft rot pathogens were 1.37, 1.38, and 1.64 mg / ml. The antibacterial effect of the three component substances on the pathogen of banana shaft rot was better than that of anthracnose. The three component substances have great potential for controlling post-harvest anthracnose and shaft rot of bananas.
