摘　　要：根据病原菌形态特征和致病性等特点,鉴定撑绿竹赤霉病的病原菌为子囊菌门肉座菌目肉座菌科的虱状赤霉(竹赤霉菌)Gibberella pulicaris(Fr.)Sacc.。对10种杀菌剂抑菌效果筛选,10%世高、50%多菌灵、60%茄苯得、80%炭疽福美对菌丝的抑制效果均80%以上,其EC50依次为0.033,310.88,528.98,770.68μg/mL。According to the pathogenicty and the morphological characteristics of pathogen, the pathogen of scab in Bamdusa pervariabilis ×Dendrocalamopsis daii was identified as Gibberella pulicaris （Fr） Sacc.. The results of the inhibitory effect of 10 tested fungicides on the hypha of pathogen showed the inhibitory effects of 10% difenoconazole WG,50% carbendazim WP,50% jiabende WP and 80% ziram-thiram of 4 pharmacy were better in the indoor medicament screening test and the inhibitory effects were all over 80% ,ECs0 of G. pulicaris were 0. 033, 310. 88, 528.98, 770. 68 μg/mL;The prevention effect of 10% Difenoconazole was the best.
