蚕豆是云南省栽培面积最大的一个冬季作物。它是人民重要的食物和牲畜主要的饲料。云南省的蚕豆感染有几种严重的病害:枯萎病,根乾腐病,黄枯萎病和茎基腐病。在高的,乾燥的田和地里面,这些病很剧烈,尤其是茎基病,甚至能将全田的蚕豆整个的毁灭。根据初步的估计,云南省全省的蚕豆因为这几种病害,平均每年损失147,000到196,000市石。这些病害的病原菌均是镰刀属的菌种。致枯萎病的病原菌是Fusarium avenaceum f fabae,致根乾腐病的病原菌是F.solani f faba,致黄枯萎病的病原菌是F.oxysporium f fame。他们的致病性不同,因此被认为是三个新的变种。在这个报告里面,曾记载有它们的形態,和在蚕豆上面所发生的病徵。致茎基腐病的病原菌是F.avenaceum。这些病菌,在去南省分仙广阔,并且很多。根据病根分离的结果,Fusarium oxysporium f fabae最多,F.avenaceum次多,F.solani f fabae较少。
Broad bean is the largest cultivated area in Yunnan Province, a winter crop. It is the people’s important food and livestock feed. There are several serious diseases of Vicia faba in Yunnan Province: Fusarium wilt, root rot, yellow blight and stem rot. In the high, dry fields and in the earth, these diseases are very intense, especially stem-based disease, and even the whole field of broad beans can be destroyed. According to preliminary estimates, broad bean in Yunnan province lost an average of 147,000 to 196,000 municipal stones annually due to these diseases. Pathogens of these diseases are species of sickle. The pathogen causing blight was Fusarium avenaceum f fabae, the pathogen causing root rot was F. solani f faba, and the pathogen causing yellow blight was F. oxysporium f fame. Their pathogenicity is different and is therefore considered as three new variants. In this report, we have documented their form and the symptoms that have occurred on the beans. The pathogen causing stem-base disease is F.avenaceum. These germs, in the southern province cents wide, and a lot. According to the results of diseased roots, Fusarium oxysporium f fabae was the most, F.avenaceum was second most, F.solani f fabae was less.
