月季黑斑病的发生与预防月季、玫瑰黑斑病是世界性病害，国内普遍发生，以为害叶片为主，其次是叶柄、叶梢、幼嫩枝和花梗。在南方和北方等地均发病较重，该病使叶片发黄早落，夏季四五月和夏末八九月病害严重时，叶片能全部落完，使月季、玫瑰秋季开花遭到毁灭性打击，并严重削弱树势。除侵染月季、玫瑰外，此病还为害蔷薇、金樱子、刺梨、黄刺玫等。一、症状叶片受侵染后，出现大小不一的紫褐色圆斑，或不规则形病斑，直径大约为4毫米至12毫米左右，边缘呈纤毛状，以后逐渐发展成黑褐色连片病斑，病斑边缘有黄晕，呈放射状，初期不十分明显；后期斑缘为紫褐色或褐色，放射状清晰可见。严重时下部叶片落光，嫩枝干枯，病斑上着生许多黑色小点粒，即病菌分生孢子盘。二、病原及发生规律病原为半知菌亚门的蔷薇盘二孢菌，是子囊菌亚门双壳孢菌，子囊盘上有包被，子囊孢子双孢。以菌丝或分生孢子盘在病残体上越冬。翌年春季产生分生孢子，借风、雨、露、洒水或昆虫传播为害。在广州地区，病害以无性方式完成其周年侵染循环，无明显越冬期。在广州以南地区、珠江三角洲一带4月中下旬进入发病期，夏季高温高湿对月季、玫瑰生长不利，植株处于“度夏”期，病情亦相对缓和。湿度比温度对病害影响更大，降雨早而多的年份发病早而重；空气湿度大，多雨、多露(雾)保护地内通风不良，容易发病，病菌可多次重复侵染，整个生长季节均可发病，尤其是梅雨季节、台风暴雨多的年份、夏季病害加重，加重发病蔓延。多雨、多雾、多露水重发病，在广州地区4至5月发病，5月中旬和8月中旬为发病盛期，9月病情有所下降。发病的适温在20至25℃左右，湿度在90%以上时发病较重，30℃以上不利此病发生。各地发病始期，末期因各地气候而异。如在潮湿多雨天气，叶片孢子6小时可萌发侵入，潜育期7至10天。特别田间渍水，养护管理不善，植株衰弱情况下发病较重，品种间抗病差异大。但土壤通透性差，肥水管理不当田间、园圃发病较重。三、防治措施夏季，月季、玫瑰生长迅速时期，侵染发病率最高，是黑斑、白粉病高发期，防病措施，应采取“防”重于“治”的原则。1、选用抗病良种。2、清除病原。坚持每年清除枯株落叶，病叶，以减少侵染病原。3、增强抗性。加强田间管理，合理施肥，增施磷钾肥，清沟排溃，不用喷淋方法浇水，适度修剪，松土培土，提高根系活力，提高长势，增强植株抗病力。4、药剂防治。翌年开春在月季、玫瑰萌发前，喷晶体石硫合剂100倍液。夏季新叶刚展开时开始喷药直至冬季。发病初期交替喷75%百菌清可湿粉剂1000倍液，或45%噻菌灵(特克多)悬浮剂500至600倍液，40%氟硅唑或25%腈菌唑乳油800倍，或40%多硫悬浮剂或50%炭疽福美可湿性粉剂或50%复方硫菌灵可湿粉800倍液、70%甲基托布津700至1000倍液、50%退菌特可湿粉剂800至1000倍液，80%代森锌800倍液、12.5%得清(斑节脱)乳油1000倍液，雨季7天喷1次，平常生长期和梅雨季节7至10天喷1次，连喷4至5次，可控制病害蔓延。发病严重时，可喷70%可杀得、30%氧氯化铜悬浮剂800倍，75%百菌清500倍，12.5%得清乳油1000倍液，连喷3至5次，7至10天喷1次。其中以12.5％得清(斑节脱)乳油1000倍液，75%百菌清500倍液防治抗效果最好。（来源：中国花卉报2003-07-24）
