Abstract:
The synergistic effect of four different fungicides was studied on severity of onion downy mildew under natural field conditions during 1998-99. Area Under Disease Progress Curve (AUDPC) was the highest in treatment where no fungicide was applied. However, it was the lowest in Dithan M-45 + Ridomil. In this treatment bulb yield, bulb size and number of bulbs were also the highest, indicating that fungicide application reduced the disease severity and stabilized onion productivity.
