Abstract:
Five fungicides were selected to inhibit the pathogen of sea-buckthorn dieback with inhibition growth rate method in lab.The toxicity of three effective agents was tested by papers on containing toxic media.And the sea-buckthorn dieback was also controlled with the three fungicides by spraying in field.The results showed that four chemical fungicides 50% carbendazim WP,70% thiophanate-methyl,25% propiconazole,70% chlorothalonil WP and one microbial fungicide Pythium oligandrum could remarkably inhibit the pathogen.The inhibiting effects of 25% propiconazole,70% chlorothalonil WP and Pythium oligandrum on the pathogen were best.The inhibition rates were all more than 80%.And the inhibiting time of the three fungicides was longer than others.The toxicity testing of three effective fungicides indicated that the toxicity of 25% propiconazole and Pythium oligandrum was great higher than that of 70% chlorothalonil.The disease incidence of three effective fungicides was obviously lower than CK,and the control efficiency were all above 70%.It was suggested that the three fungicides could be used to control sea-buckthorn dieback disease in the field.
