在湖南,辣椒炭疽病、灰叶斑病和疮痂病,是三种常见和严重为害辣椒叶片的病害。受害病株均在叶片上产生近圆形或不规则形的病斑,大小约2毫米,易破裂或穿孔。病害严重时,引起大量落叶。病害在苗期和成株期均有发生。3月上、中旬在苗床开始出现个别病斑,4月中、下旬叶片上病斑大量产生,引起苗期落叶。成株期在5月下旬～6月上旬出现发病中心,6月中、下旬为发病盛期。病害发生的轻重与雨水多少成正相关。结露持续时间长,土壤潮湿,排水不良,种植过密,施肥不足,或偏施氮肥,均利于发病。
In Hunan, pepper anthracnose, gray leaf spot and scab disease are the diseases of three common and severely damaged peppers. The diseased plants all produce nearly round or irregular spots on the leaves, about 2 mm in size, which are easily broken or perforated. Severe disease caused a large number of leaves. Disease occurs at seedling and adult stage. In March, middle and early seedbed began to appear in individual lesions, in mid-April, late leaves a large number of spots on the leaves, causing seedling leaves. Adult stage in late May ~ early June incidence center, in mid-June for the peak incidence. The severity of the disease is positively related to the amount of rainwater. Condensation for a long time, soil moisture, poor drainage, planting too close, inadequate fertilization, or partial nitrogen fertilizer, are conducive to the incidence.
