dc.description.abstract | Brinjal (Solanum melongena L.) is an important vegetable crop of Saurashtra belongs to the Family: Solanaceae. In India, it is grown throughout the country. It is known to affect by many parasitic diseases. Among them, Alternaria leaf spot caused by Alternaria alternata is an important disease of brinjal, which diminish the quality and yield under field condition. Considering the economic importance and regular occurrence of the disease in moderate to severe form in Saurashtra region, the present study on "Alternaria leaf spot [Alternaria alternata (Fr.) Keissler] of brinjal and its management" was carried out at the Department of Plant Pathology, Junagadh Agricultural University, Junagadh using fungicides and also to identify the available genotypes/varieties resistant against the disease under field condition. Naturally infected leaf sample of brinjal showing the typical characteristics symptoms of Alternaria leaf spot disease were collected from the Vegetable Research Station, JAU, Junagadh. Isolation of the fungus was made by using tissue isolation method and purified by single spore isolation technique on PDA medium. The symptoms initially characterized by small, necrotic, scattered, brown, circular spots with varying size. Later on, it becomes irregular in shape with typical concentric rings, which coalesced to form big irregular patches on leaves exhibited blighted appearance and eventually, results into withering and shedding of the leaves. Pathogenicity of A. alternata was proved by adopting four distinct artificial inoculation techniques on brinjal leaves viz., pin prick, tooth brush injury, injury by carborundum powder and spray without injury. Each inoculation techniques effectively proved the pathogenicity. However, pin prick inoculation method was more effective than other techniques. | |
