摘要
2010年在我国广东省首次报道了由侵管新赤壳菌(Neocosmospora vasinfecta)侵染引起的花生新赤壳菌基腐病。罹病花生植株萎蔫、植株茎基部和根系变黑腐烂,在潮湿条件下,罹病部位有浅红色子囊果。这是我国大陆首次报道的花生新病害。该病害在广东省的多个市县有发生,严重的发病率高达30%。除广东省外,该病在我国江西省也有分布和危害,其致病菌可进一步鉴定为侵管新赤壳菌非洲变种(N.vasinfecta var.africana)。在广东省也发现了由侵管新赤壳菌侵管变种(N.vasinfectavar.vasinfecta)引起的大豆茎枯病。对侵管新赤壳菌的文献进行了简要的综述。
