摘要
本文研究了广东万年青炭疽病病原菌形态，培养性状以及ｐＨ值和杀菌剂对该菌的影响，结果表明该病原菌为盘长孢状刺盘孢（Ｃｏｌｅｌｏｌｒｉｃｈｕｍｇｌｏｅｏｓｐｏｒｉｏｌｄｅｓ（Ｐｅｎｚ）Ｓａｃｃ）组．分生孢子在２５℃下萌发最好，菌丝生长的最适条件是２０—２５℃，ｐＨ值５—６．药剂多丰农对该菌有明显的抑制作用．
The experiments were about the morphology,culture property and sensitivity on pH and fungicides of anthracnose collecting from Agluonema modestwu Schott et Eng1.The results Showed the pathogenic fungi of anthracnose was Colletorichum gloeosporioieds (Penz) Sacc.At 25℃,spore germination rate was the highest. he optimum growth condition of hypha was20￣ 25℃and PH 5-6.Duofeng Nong(anew fungicide)controlled effectivelly the disease dcvelopment in the laboratory or in the field.
