摘要
从安徽省姜主要种植区采集姜瘟病株,分离纯化出10个姜瘟病菌菌株,对其致病性、形态、染色反应、生理生化等性状和生产上常用药剂对病菌的毒力进行了测定。结果表明:安徽省姜瘟病病原为茄罗尔氏菌[Ralstonia solanacearum(Smith) Yabuuchi et al],以生物型Ⅲ为主,也有生物型Ⅳ分布。在供试的8种药剂中,以40%爱诺.链宝对姜瘟病菌的抑制效果最好,其次是Kocide,克菌康和菌鲨在较高浓度(>100 mg/L)时也有一定的抑制作用,根腐灵、速补、敌克松即使高浓度下对病菌仍无抑制作用。
Ten strains of ginger bacterial wilt were separated and purified from the diseased plants collected from the main ginger-predueing regions in Anhui province and their characters of pathogenicity, morphology, dyeing reflection, and physiological and biochemical properties and the toxicity of common bactericides to pathogen in production were detennined. Results showed that the pathogens of ginger bacterial wilt belonged to Ralstonia solanacearum （Smith） Yabuuehi et al and divided into two biotypes, biotypes Ⅲ and Ⅳ according to their ability of utilizing 3 sugars, 3 alcohols and dehydrogenation. Among 8 tested bactericides, the inhibitive effect of 40% Ainolianbao on pathogens of bacterial wilt of ginger was best, followed by Kecide, Kejunkang and Junsha, which had also certain inhibitive effect on the pathogenic bacterium under the high concentration（ 〉 100 mg/L） ,while Genpuling, Shupa and Dikesong had no inhibitive effect against the pathogenie bacterium even under the high concentration.
