Abstract:
Oilseed Brassica spp. is found to be one of the most important diseases of oilseed crop in the world. It is susceptible to a number of diseases which is generally caused by the living pathogen. The most destructive disease in the world is found to be Alternaria black spot diseases which is surrounded with yellow colours. Character of the diseases is generally known by the different names which are going to be follows, Alternaria brassica, Alternaria brassicae, and Alternaria raphani. Alternaria leaf spot disease cause reduction in defoliation which produce lesion around stem, leaves and silique. These types of pathogens are found to be the air borne, seed borne and soil borne diseases. The leaf spot of diseases is generally caused by the heavy rainfall and the weather with the more disease’s incidence. The severity of the diseases is also responsible for Conidial age of the host plant. This disease is more prominent during the summer seasons where the temperature falls 27- 28 ᵒC. This paper also determines the development of Alternaria leaf blight in Mustard crop in relation to the pathogen such as taxonomy, biology, epidemiology, and their management through, biological, chemical, cultural and botanical approaches. Alternaria leaf blight of mustard plant represents the future outlook and well qualified strategy.
