这种真菌能使花生产生枯萎、根腐、茎腐(干腐、炭腐、灰茎腐),也可使花生叶片产生叶斑,还能使荚壳与种仁产生腐烂(黑荚),当病菌生长在种仁的子叶上时还能产生隐藏的腐烂。炭腐菌(M.phaseoli)已在世界各地多种寄主和土壤中发现,能为害蚕豆、向日葵、甘薯、甜瓜、番茄、玉米、高粱及许多杂草。现在研究范围已类似甘薯黑斑病。病菌对花生成株影响很小,有些地区荚果在土壤里开始成熟时受害较重。Bouriquet与Jaubert报导在Senegal地区花生种子因受该病为害减产34％。现已报导的有冈比亚、阿根廷、委内瑞拉、印度、以色列和美国花生上发现炭腐病。
This fungus can make peanuts produce wilt, root rot, stem rot (dry rot, charcoal rot, ash stem rot), but also can produce leaf spots on peanut leaves, but also make the pod shell and kernel rot (black pods) When the bacteria grow in seed cotyledons can also produce hidden decay. M.phaseoli has been found in many hosts and soil around the world and can harm broad beans, sunflowers, sweet potatoes, melons, tomatoes, corn, sorghum and many weeds. Now the scope of the study has been similar to sweet potato black spot disease. Bacteria have very little effect on the formation of peanuts, and in some areas the pod harms more heavily when it begins to mature in the soil. Bouriquet and Jaubert reported a 34% reduction in peanut seeds in the Senegal area due to the disease. It has been reported that charcoal is found on peanuts in the Gambia, Argentina, Venezuela, India, Israel and the United States.
