Abstract:
Taking Trichoderma T2 as material,the control effect of 9 chemical fungicides to Botryosphaeria dothidea was studied by means of mycelium growth rate method,and mixture the biocontrol bacterium and 5 best chemical fungicides respectively,the compound of biocontrol bacterium and chemicals fungicides was studied,and to explore the interior control effect of the mixture for Botryosphaeria dothidea.The results showed that the synergistic ratio was the highest at the Zhongshengmycin concentration of 2 000 times concentration mixture the Trichoderma T2,with the synergia ratio of 1.23 after 24 hours,and the synergia ratio of 1.36 after 48 hours.Zhongshengmycin,as the chemical factor of combination research,could inhibit the growth of Botryosphaeria dothidea under lower usage level,and also was compatible with strain Trichoderma T2.Meanwhile,the combination of Zhongshengmycin and Trichoderma T2 not only could promote the biocontrol effectiveness,but also reduced the usage of chemicals.
