Marigold (Tagetes erecta L.) is an important commercial ornamental crop grown in India. Among the diseases the leaf and bud blight caused by Alternaria zinniae is the major constraint in marigold cultivation. There are different methods of disease management but in general chemical management is considered to be most effective method for management of aerial diseases. The three year pooled results revealed that four sprays of iprodine + carbendazim 0.2% at 10 days interval starting the first spray at disease appearance showed significantly the least leaf blight intensity (4.41%), maximum disease reduction (89.73%), least bud blight intensity (1.33%), maximum flowers per plant (25.83) with more weight of flowers (232.0 g).
Keywords: percent disease reduction (PDR), percent intensity and blight
