Abstract

The infected parts of the tomato plant were collected from Jitpurphedi of Kathmandu, Nepal. The isolated fungi from the infected parts were Septoria lycopersici, Cladosporium oxysporum responsible for leaf spot, Phytophthora infestans and Rhizoctonia solani responsible for leaf blight, Cladosporium cladosporioides responsible for fruit rot, Leveilulla taurica responsible for powdery mildew and Plasmopara viticola responsible for Downey mildew disease. In the survey period, the highest incidence was found at leaf blight (30.08%) and the lowest at stem rot (4.64%). In the case of severity, the maximum severity was found at Downey mildew (77%) and the minimum was recorded at fruit rot (5.25%).
加德满都谷地番茄真菌病害研究
番茄植株的感染部位采集自尼泊尔加德满都的Jitpurphedi。从侵染部位分离得到的真菌分别是导致叶斑病的番茄红霉、尖孢枝孢霉、导致叶枯病的番茄疫霉、导致果实腐烂的枝孢霉、导致白粉病的牛皮枝孢霉和导致唐尼霉病的葡萄浆霉。调查期内,叶枯病发病率最高(30.08%),茎腐病发病率最低(4.64%)。就严重程度而言,唐尼霉病的严重程度最高(77%),果腐病的严重程度最低(5.25%)。
