Abstract
Abstract
In order to screen out essential oils with better inhibitory effects on Rhizopus stolonifera and their appropriate concentrations, an in vitro antibacterial and drug susceptibility tests was conducted to determine the effects of 32 essential oils on the growth of grape R. stolonifera. The results showed that 1000 μl/L of clove, geranium, agilawood and lovage essential oils could completely inhibit the growth of R. stolonifera within 48 hours. Through follow-up verification, it was found that 1000 μl/L of clove, geranium and lovage essential oils had a continuous inhibitory effect on the growth of R. stolonifera, and the inhibition rate was continuing to 100% from 2 to 8 days. When the concentration was 250 μl/L, only lovage essential oil had high inhibition rate. Therefore, lovage essential oil can effectively inhibit the growth of R. Stolonifer on grape, and the appropriate concentration should not be less than 250 μL/L.
