摘　　要：琯溪蜜柚黑斑病(pomelo black spot)的病原菌为亚洲柑橘叶点霉Phyllosticta citriasiana。田间系统观察和病原菌侵染试验结果表明,蜜柚黑斑病是一种潜伏侵染病害,上年度被侵染的带菌叶片为次年病害的侵染源,蜜柚花期至幼果期是病菌侵染盛期和病害防治适期。如果错过这两个时期,将难以达到理想的防治效果。Phyllosticta citriasiana is the pathogen of pomelo(Citrus maxima)black spot.Systematic field observation and pathogen infection test showed that pomelo black spot was a latent infection disease,the infected leaf in the previous year was infection source of the disease in the next year,and the period from flowering to young fruit of pomelo was the infection peak period and disease control optimum period.If these two periods were missed,it will be difficult to achieve an ideal control effect.
