摘要
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 blight of cross bamboo was a new disease first found in Gaofeng forest farm, Zhegujiang horticulture farm and Sanmenjiang forest farm of Guangxi Province. By the tests of isolation and culture, Fusarium sp. was got from the diseased plants. In-vitro inocolation and reisolation tests were done during bamboo shoot period and the results showed that the blight fungi had strong pathogenicity to hybrid bamboos and could bring some natural symptoms. Therefore, it was a chief pathogen. The results of the virulence tests of 12 germicides such as Inezin and Carboxin showed that 30% Inezin WP, 40% Carboxin WP, 40% Thiophanate-methy WP and 70% Fenaminosulf SP were effective against the blight.
