摘要

摘要: 报道了广东农田杂草上的12种病原真菌。它们是空心莲子草上的莲子草假隔链格孢（Nimbya alternantherae),马唐上的灰梨孢（Piricularia grisea）,红花酢浆草上的酢浆草假尾孢（Pseudocercospora oxalidis)，丁香蓼上的月见草假尾孢（P.oenotherae)，水蓼上的扁蓄假尾孢（P.avicularis)，土荆芥上的甜菜生尾孢（Cercospora beticola），积雪草上的积雪草壳针孢（Septoria centellae)，扁穗牛鞭草上的牛鞭草孢堆黑粉菌（Sporistorium lepturi)，看麦娘上的看麦娘单孢锈菌（Uromyces alopecuri)，两耳草上的雀稗柄锈菌（Puccinia paspalina)，裸花鸭跖草上的鸭跖草囊壳孢（Physalosporn commelinae) ,莲子草上的苋白锈菌（Albugo bliti)。讨论了这些真菌作为杂草生防真菌应用的可能前景。

Abstract: Twelve species of pathogenic fungi from the weeds in field in Guangdong province were found and described. They were Nimbya alternantherae from Alternanthera philoxeroides,Piricularia grisea from Digitaria adscendens,Pseudocercospora oxalidis from Oxalis corymbosa,P. oenotherae from Ludwigia prostrota, P. avicularis from Polygonum hydropiper,Cercospora beticola from Chenopodium ambrosioides,Septoria centellae from Centella asiatica,Sporisorium lepturi from Hemarthria compressa, Uromyces alopecuri from Alopecurus aequalis,Puccinia paspalina from Paspalum conjugatum,Physalospora commelinae from Commelina nudiflora,and Albugo bliti from Alternanthera sessilis. Among them, N. alternantherae,P. oxalidis,C. beticola and U. alopecuri could be potential mycoherbicides in future.
