The experiment was conducted under in vitro and pot culture Pythium myriotylum is a notorious soil-borne oomycete causes post-emergence damping off in chilli pepper. Damping-off is a term applied to a very common trouble in which seedlings are attacked by soil-inhabiting fungi usually just at the soil level on to hypocotyl or upper taproot causing partial or complete rot and the seedlings suddenly topple over in a characteristic manner. Damping off of chilli: This disease prevalently occurs and greatly damages many plants such as chilli, tomato and brinjal belonging to family Solanaceae in India. BK08 decreased more damping-off rather than others. Lack of proper space among the seedlings was … Among different biotic constraints, anthracnose disease is the major limiting factor affecting yield and production of chilli crop. Hence we concluded that, T. harizanum can be recommended not only for the control of damping off disease in chilli plants and also to enhance the growth of the plants [3]. is responsible for 90 per cent mortality either as pre or post-emergence damping off in nurseries and field conditions.
