补充资料:百日草叶斑病的防治
    百日草叶斑病多发生在夏季,高温高湿有利于发病,一般危害开花后的成熟植株,病状为叶片上初生浅红至暗褐色小点,逐渐扩大为圆形或多边形病斑,四周有黄色晕圈,病斑发展迅速,发展至茎部,可使茎部变黑变干,植株迅速死亡。
    叶斑病发生普遍,发展迅速,危害严重,从初发至叶片干枯只需一周左右的时间,如不及时防治将使植株迅速死亡。病菌主要在种子越冬,也可随病残体在土壤中越冬,植株生长期的病菌能通过风雨传播。
    防治细菌性叶斑病要点:
    第一,要选用抗病品种和有技术保证条件下生产的种子。
    第二,培养壮苗,增强抗病能力。百日草喜温暖(20℃以上)阳光充足环境,要求排水好、疏松肥沃的土壤,较耐干旱。无论是苗期还是花期,浇水均应适当,同时要给植株以足够的生长空间。
    第三,种子播种时可进行土壤和种子消毒,可选用新植霉素200mg/L浸种子2至3小时,也可用50%琥胶肥酸铜拌种,并喷洒床土。生长季节发病可用53.8%的可杀得2000,浓度为1000倍,或杀菌王1000倍液,或72%的农用硫酸链霉素3000倍液,喷洒叶面每周一次,连续3至4次,会收到明显的效果。(来源:《中国花卉报》2004.01.29)
