| 摘 要： | 以硫酸链霉素为对照药剂,通过平皿抑菌试验和活体药效试验,对3%中生菌素用于防治糙皮侧耳(Pleurotus ostreatus)细菌性褐斑病的效果进行评价。结果表明,3%中生菌素(37.57、5.0 mg/L)与硫酸链霉素(250 mg/L)对托拉斯假单胞杆菌(Pseudomonas tolaasii,细菌性褐斑病病原菌)的平皿抑制率均为100%;活体药效试验中,3%中生菌素(37.5 mg/L)与硫酸链霉素(250 mg/L)对糙皮侧耳细菌性褐斑病的预防效果均在80%以上,显著优于接种后施药处理的治疗效果。

| Abstract: | Plate tests and in situ efficacy trials were conducted to evaluate the effect of zhongshengmycin wettable powder(WP) containing 3% active component on brown blotch disease of Pleurotus ostreatus caused by Pseudomonas tolaasii.Both zhongshengmycin WP(75.0 and 37.5 mg/L) and streptomycin(250 mg/L) were 100% inhibitory to P.tolaasii in plate tests.When applied to the fruit bodies before inoculation with P.tolaasii,both zhongshengmycin WP(37.5 mg/L) and streptomycin(250 mg/L) were >80% effective in preventing infection,which was approximately double the level of protection recorded when the antibiotics were applied after challenge with the pathogen. |
