Synergistic Effect of Chemical Antibacterial and Trichoderma Harzianum on Houttuynia Cordata Southern Blight Disease Caused by Sclemtium Rolfsii
In order to provide guidance for safely and efficient control to Southern blight disease of Houttuynia cordata ,the antibacterial activities and antagonism were used to chose the chemical antibacterial which is able to synergistic control the Southern blight disease caused by Sclemtium Rolfsii with Trichoderma Harzianum T2 - 16, and pot experiment was used to testify the synergistic effect of chemical antibacterial and Trichoderma harzianum . The results showed that the triazolone possessed good growth inhibition effect to Sclemtium Rolfsii ,but it weakly inhibited to the Trichoderma harzianum .To control the Southern blight disease caused by Sclemtium Rolfsii, spraying the triazolone 250 μg∕ml solution simultaneously broadcasting the Trichoderma harzinum 30 g∕m2 conidial preparation, the best control effects could achieve, it was better than using the triazolone or Trichoderma harzinum alone .
