title: [Inhibition effects of wood vinegar on Alternaria panax and Botrytis cinerea].
abstract: OBJECTIVE
  Less fungicides could be used to biocontrol Alternaria panax and Botrytis cinerea, this experiment can offer preliminary theory for wood vinegar as a botanic fungicide.
  
  
  METHODS
  The in vitro inhibition activities of wood vinegar on Alternaria panax and Botrytis cinerea were tested by using mycelial growth rate method and spore germination method.
  
  
  RESULTS
  Inhibition of mycelium growth rate to Alternaria panax was 100% when the concentration of wood vinegar was no less than 3.0%, while the inhibition of mycelium growth rate and spore germination rate were 70.68% and 84.47%, respectively, at concentration of wood vinegar 2.25%. Inhibition of mycelium growth rate and spore germination rate to Botrytis cinerea were 100% when the concentration of wood vinegar was no less than 2.25%.
  
  
  CONCLUSIONS
  Wood vinegar concentration of no less than 2.25% can be used as a biocontrol agent of Alternaria panax and Botrytis cinerea, it is useful for the further field trial.
