Abstract
Onion (Allium cepa L.) is most profitable spice-vegetable crop in India, but it is susceptible various fungal, bacterial, viral and nematode diseases which affects bulb production. Among several fungal diseases anthracnose and anthracnose-twister complex are the major destructive diseases incited by Colletotrichum gleosporioides and Fusarium moniliformis in all cropping seasons particularly kharif onion leads 80% yield losses in field which causes shortage of onion in the market as a result there will be increase in the onion price. So ultimately famers rely on chemicals to manage the disease which raise the production costs and cause problems for the environment and human health. This article's emphasis on symptomatic diagnosis, favourable factors that led to the epidemic of the disease and integrated management strategies to tackle the threat will be extremely helpful to onion growers, students, extension workers and other onion researchers.
