竹黑粉病发生在毛竹、淡竹等多种竹种上。每年发生一次,春梢产生黑粉后即枯死,第二次梢不发病。病笋端部也产生黑粉,引起退笋。病菌厚垣孢子无休眠期,在10～28℃下萌发,但以20～24℃为最适。在相对湿度93％时才开始萌发,98～100％时萌发率最高。在适宜温度下2h即开始萌发,10h即达到萌发高峰。萌发时产生一个很短的芽管,并以芽殖方式产生担孢子。厚垣孢子的寿命只有一个月左右。病株多为全株发病,年年发病,竹鞭常相连,很可能是系统侵染性病害。
Bamboo powdery mildew occurs in bamboo, bamboo and other bamboo species. Occurs once a year, the spring shoots black powder that is dead, the second shoot is not disease. Soy shoots also produce black powder ends, causing the retreat of bamboo shoots. Chlamydospore no pathogen dormancy, germination at 10 ~ 28 ℃, but to 20 ~ 24 ℃ for the most appropriate. The germination began at 93% relative humidity, with the highest germination rate at 98-100%. 2h at the appropriate temperature that germination, germination peak reached 10h. When germinated, a very short germ tube is produced, and basidiospores are produced by budding. Chlamydospores life is only about a month. Most of the diseased plants for the whole disease, annual incidence, often linked to bamboo whip, is likely to be systemic infective disease.
