Study on isolation, purification and identification of gladiolus disease

Abstract

Flower plays an important role in people’s celebration and everyday lives. Among the floriculture, gladiolus is one of them. Cultivation of gladiolus flower produces huge emphasis due to less maintenance and high economic return. Even though, the diseases on gladiolus have major economic impact on quality and quantity. The objective of study was to record fungal disease (s) on gladiolus. The gladiolus crop was found infected with different fungal diseases i.e. wilt (Fusarium oxysporum f. sp. gladioli), corm rot (Rhizoctonia solani) and leaf spot (Alternaria alternata) during survey in kharif 2012. Therefore, by considering the economic losses, an investigations and experiments were carried out during 2012-2013 at Department of Plant Pathology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The observations on Pathogenicity of Fusarium oxysporum f. sp. gladioli, Rhizoctonia solani and Alternaria alternata which caused wilt, corms rot and leaf spot disease on gladiolus, respectively was proved. The Curvularia lunata was invariably isolated from diseased samples but showed non-pathogenic reaction on gladiolus.
