Taxonomically, genus Alternaria comes under Deuteromycetes phylum which includes different saprophytic and endophytic species. It is famous due to its notoriously destructive pathogens. It majorly affects various plant families e.g. Cucurbitaceae, Cruciferaceae and Solanaceae which are agriculturally important crops possess high nutritional and economical values. The crops suffer from various bacterial, viral, fungal and nematode diseases. Among the above mentioned diseases, early leaf spot disease caused by pathogen Alternaria solani is one of the most devastating diseases resulting in loss upto 78%. Most of the species of Alternaria lacking in teleomorphic stage whereas few species have teleomorphs in their disease cycle. Alternaria being necrotrophic it leads to severe damage to plant and its produce. Besides the involvement of toxins in pathogenesis or invasion, few genes or gene products also have major effect on pathogenicity. In the present review, we described in detail about efficiency of plant and herbal extract, bio control agents, cow by products and fungicides against A. solani, that not only effective in managing the disease but also economic and ecofriendly.
