毛花雀稗是我国南部热带和亚热带地区多年生暖地型优良牧草,耐寒、耐旱、没有夏枯现象,适口性好,四季常青产草量高的牧草。毛花雀稗种子产量常因感病而下降,经考察研究,毛花雀稗穗期病害除已有记载的麦角病外,还有毛花雀稗炭疽病(Ascochytarabiei)和红粉病(Trichotheciumroseum)。毛花雀稗炭疽病可由种子带病传病。种子带病检测隔年的种子表面基本不带菌,因此用隔年的种子种植可以减轻病害的发生程度 Paspalum is a pasture with perennial and warm type in the tropical and subtropical regions of China. It is hardy, drought tolerant, without summer droughts, has good palatability, and has high evergreen yield. Paspalum seed production often declined due to susceptibility, the study found that the disease of barnyardgrass maize disease in addition to the previously documented ergot disease, but also the male flowers Paspalum anthracnose (Ascochytarabiei) and powdery mildew (Trichotheciumroseum) . Barnyardgrass anthracnose can be transmitted by seed disease. Seeds sick next year, the seed surface is almost no detection, so the next year’s seed planting can reduce the incidence of disease
