The Control Test of Different Biological Agents against Mulberry Fruit Sclerotiniosis

    Graphical Abstract
    • Abstract
  • Purpose In order to control of mulberry fruit sclerotiniosis and to improve the fruit quality of mulberry, different biological agents were screened out through the control efficiency experiments of biological agent.
    Method By field experiment, we selected 5 kinds of biological agents, 2×108 CFU/g Trichoderma viride (WP), 3% mesoin (WP), 47% kasugamycin·copper oxychloride (WP), 3×108 CFU/g Trichoderma harzianum (WP), 4% pyrimidine nucleoside antibiotics (water agent) , each biological agent with three concentration gradients. Five different biological agents with different diluents were sprayed on the mulberry trees separately at the early flowers stage, full flowers stage and final flowers stage.
    Results Five kinds of biological agents had different control effects on the mulberry fruit sclerotiniosis and the control efficiency rose with the concentration increasing.
    Conclusion 2×108 CFU/g tylenol Trichoderma wettable powder diluted with 300–800 times had 69.76%–84.02%, close to the control effect of pythium which is mainly used in biological agents, therefore, it can be used as the prevention and control drug for mulberry fruit sclerotiniosis.
