Research on Biological Feature of Low-late Pomelo Blast and Screening of Fungicide

WANG Ming-hong et al (China Agricultural University,Beijing 100094)  
Low-late pomelo blast is caused by Fusarium oxysporum Schlecht.The experiment in the conidiophores and hypha growth in different temperatures,relative humidities,illuminations and pH values were done.The result showed that 30?℃,RH 90%,full illumination and neuter or alkalescence were suitable for the germination of conidiophores and 25~30?℃,RH over 75%,any illumination and neuter or acidic for hypha growth in these suited conditions.Another experiment in the screen with eleven fungicides was made and the result showed that 50% carbendazim 1?200,50% phenzine oxide at dilutions of 1 000,64%oxadixyl 600,53.8% cocide 1?000,urbacid 1?200 or 70% thiram 1?000 were good for preventing conidiophores and hypha.
