摘  要：
以对番茄溃疡病菌拮抗效果良好的西唐链霉菌(Streptomyces setonii)菌株Z-L-22为研究对象,开发出3种大田应用剂型——水剂、颗粒剂和片剂,确定了片剂最佳发酵组分,并测定不同剂型在温室和棚室对番茄溃疡病的防治效果。温室试验结果表明,10×发酵液稀释液、固体发酵物5g和片剂1g于番茄定植时施用,对番茄溃疡病防效可达到80%以上;棚室番茄定植75d后,经过水剂、颗粒剂、片剂处理后的番茄发病率和严重度均显著低于硫酸链霉素处理和空白对照。其中片剂由于具有成本低、易储存运输、持效期长等优点,有很高的开发价值。

摘  要：
Based on the strain of Streptomyces setonii Z-L-22 which has strong antagonism effect on bacterial canker of tomato,we developed three types of field application formulations-water agent,granules and tablets,and determined the best components of tablets.The control effect against bacterial canker of tomato was investigated in greenhouse and field.The results showed that control efficacy reached over 80% when10 times diluted fermentation,5 g solid,and 1g tablet were applied in the greenhouse.Field test demonstrated that the incidence and severity of the three formulations treatments were significantly lower than those of streptomycin sulfate treatment and blank control after 75 days.The tablets showed easy in storage and transportation,low cost and long effective period,so it had a good value for development.
