摘要
从云南省文山州三七产地采集的根腐病标本分离出三种致病镰刀菌,即茄病镰孢(Fusarium solani(Mart)Sacc);尖孢镰孢(Fusarium oxysporumSchl);串珠镰孢中间变种(Fusarium moniliform Var.intermeclium Neish＆Keggett).其中后两种为首次报道.选用11种杀菌剂进行室内带药PDA平板抑菌和田间灌根试验,以甲霜灵锰锌和杀毒矾防效最佳.
Three pathogenic Fusaria; Fusarium solani (Mart) sacc., F. oxysporum Schl., F, monili-form Var, intermedium Neish & Leggett, were isolated from the specimens of Pseudoginseng root rot collected from Wenshan, Yunnan. The last two Fusaria are repotted first in China. The results of the PDA plate bacteriostatic experiment indoor and root syringe experiment in field with 11 germicides showed that the metalaxy + mancozeb and oxadixy +mancozeb had the best control effect.
