摘要
2001-2004年调查了淡竹Phyllostachys glauca竹秆锈病Stereostratum corticioides在河南省洛宁县的发生危害情况,开展了药剂防治试验。结果表明,该病在湿度大、光照弱的竹林发病重,冬孢子堆主要分布在淡竹1 m以下部位。1-2月人工刮除冬孢子堆对新发生的竹秆锈病有良好控制效果,10月上旬和次年3月下旬用20%粉锈宁5倍液2次涂抹冬孢子堆,防治效果90%以上。
Infestation investigation and control experiment of bamboo rust, Stereostratum corticioides, on Phyllostachys glauca were carried out during 2001 - 2004. The result showed that bamboo rust occured more frequently in moist, shadow bamboo field. The winter spores mainly distributed on the bamboo stems below 1 m. Scraping winter spores on newly infected bamboo stems from January to February was effective. Painting 20 % triadimefon EC （diluted 5 times） on winter .spores twice in early October,late March the next year could rescue more than 90 % of the infected bamboo and the amount of newly emerged winter spores was low.
