Abstract:
Oilseed Brassica spp. is one of the most important diseases of oilseed crop in the world. Rapeseed mustard are susceptible to a number of diseases which is caused by the living (biotic) pathogen. It is also known as Alternaria black spot diseases surrounded with yellow colours on the leaves which is known to be the most destructive diseases in the world. This disease is generally characterised by the different names which are as follows, Alternaria brassica, Alternaria brassicola and Alternaria raphani. Alternaria leaf spot pathogen produces lesion around the leaves, stem, and the Silique which cause reduction in defoliation. These pathogens are seed borne, soil borne, and airborne diseases. Alternaria leaf spot diseases caused by the heavy rainfall and the weather with the highest diseases incidence. The Conidia, age of the host plant is also responsible for severity of the diseases. This disease is more prominent during the summer seasons where the temperature falls 27- 28 0C. This paper also determines the development of Alternaria leaf blightin Mustard crop in relation to the pathogen such as taxonomy, biology, epidemiology and their management through biological, chemical, cultural and botanical approaches. It represents the future outlook and their strategy for Alternaria leaf blight of rapeseed mustard plant.
