Abstract:
Onion twister disease caused by Colletotrichum gloeosporioides, Fusarium oxysporum and Meloidogyne incognita which causes heavy losses to the crop. To study the effect of soil moisture on the development of twister disease of onion, an experiment was conducted in sick pots. Onion seedlings were transplanted in pots, pathogens were inoculated and different soil moisture were maintained. It was observed that C. gloeosporioides inoculated plant showed cent percent disease incidence at 50, 60 and 70 percent moisture level. F. oxysporum inoculated plants showed maximum disease of 77.38 percent at 50 percent moisture level. M. incognita inoculated plants showed maximum disease (55.71%) at 60 percent moisture level. C. gloeosporioides + F. oxysporum + M. incognita combined inoculation showed cent percent disease incidence at 50, 60 and 70 percent moisture levels.
