摘要

Kura clover (Trifolium ambiguum M. Bieb.), a rhizomatous, persistent legume native to the Caucasus region, has received recent attention in North America and New Zealand as a pasture and silage crop. It is reported to be resistant to most pathogens affecting other clovers, including Sclerotinia trifoliorum Eriks. (3,4), one of the most destructive pathogens of clovers in northern Europe. Kura clover (cv. KTA202) was established in May 2009 near Moche?ek, Poland (53° 13′ N, 17° 51′ E) on a Luvisol soil. By May 2011, 70% of plants grown in an experimental field (350 m2) had died, and 20% of the remaining plants were yellow and wilted. At crowns and the lower stem regions, wet, brown lesions with delicate white mycelium were observed. Lesion development was followed by death of the entire plant in a few days.

Bieb。）是一种根茎，持久的豆科植物，原产于高加索地区，最近在北美和新西兰作为牧草和青贮饲料获得了关注。据报道，它对影响其他三叶草（包括小核盘菌）的大多数病原体具有抗性。 （3,4），北欧三叶草最具破坏性的病原体之一。库拉三叶草（CTA。KTA202）成立于2009年5月，位于波兰Moche？ek附近（北纬53°13′，东经17°51′）上。到2011年5月，在试验场（350 m2）上生长的植物中有70％已死亡，其余20％的植物已黄化并枯萎。在冠部和下部茎部区域，观察到湿润的，褐色的病变，带有细腻的白色菌丝体。病变发生后几天内整个植物死亡。
