| 中文摘要: |
| 2012-2015年，在海南省辣椒主产区发生了一种严重危害辣椒的叶斑病，从发病叶片中分离到一种细菌,通过致病性测定、柯赫氏法则验证及分子生物学鉴定,将引起该病害的病原鉴定为野油菜黄单胞菌辣椒斑点病致病变种(Xanthomonas campestris pv. vesicatoria)。选用8种杀菌剂通过平板对峙法对该病原进行了室内毒力测定,结果表明:其中6种药剂对该病原有抑菌效果,效果最好的为72%农用硫酸链霉素可湿性粉剂,47%春雷·王铜可湿性粉剂次之,2%春雷霉素水剂和20%噻菌铜悬浮剂没有抑菌效果,不同药剂之间或同一种药剂不同剂型之间抑菌效果差异较大。病原鉴定和药剂筛选可为该病害的诊断和防治提供科学依据。 |
| 英文摘要: |
| In 2012-2015, a serious pepper bacterial leaf spot disease occurred in the main producing areas of Hainan Province. A bacterial strain was isolated from the diseased pepper leaves, and identified as Xanthomonas campestris pv. vesicatoria by pathogenicity test, Koch’s postulates and molecular identification. Toxicities of 8 kinds of bactericide were tested by plate confrontation method. The results showed that 6 agents have antibacterial effects, and 72% streptomycin WP was most effective, and followed by 47% kasugamycin· copper oxychloride WP,while 2% kasugamycin AS and 20% thiodiazole copper SC have no inhibitory action. Antibacterial activity differed significantly between the different agents, and the same agents with different formulation also had different antibacterial effects |
