杂交竹枯萎病是近几年在广西高峰林场、三门江林场、柳州市的鹧鸪江园艺场等地发现的新病害。经多次分离培养获得镰刀菌Fusarium纯培养。通过竹笋期的室内有伤、无伤的多次反复接种和再分离试验证明病菌对杂交竹有很强的致病力,并能引起与自然发病一致的症状,是杂交竹枯萎病的主要病原菌。枯萎灵、萎立等12种杀菌剂的毒力测定结果表明:30%的枯萎灵WP、40%萎立WP、40%的托福灵WP、70%根腐灵SP对该病菌的生长有较强的抑制力。
The hybrid bamboo blight is a new disease discovered in recent years in Gaofeng Forest Farm, Sanmen River Forest Farm and Liuyuan City, partridge farm horticultural field. Fusarium Fusarium pure culture was obtained after multiple isolation and culture. Through bamboo shoots indoor injury, repeated injury and repeated inoculation and re-separation test showed that the bacteria on the hybrid bamboo has a strong virulence and can cause symptoms consistent with the natural disease is the main pathogen of hybrid bamboo blight . The results of the virulence test of 12 fungicides such as withered wither and wilt showed that WP of 30%, WP of 40%, WP of 40%, WP of 70% Strong inhibition.
