Abstract
The efficacy of two pi ant products, viz., ajoene, a constituent of ga rlic (Allium sativum), and neemazal, a product of neem (Azadirachta in dica), was evaluated in the field individually and also in combination s during 1995-96 and 1996-97 cropping seasons. Both the products at di fferent concentrations (Neemazal 50, 150, 250 mu g ml(-1); Ajoene 100, 500, 750 pg ml(-1) and their combinations) reduced disease intensity of powdery mildew of peas as compared to control. Yield parameters wer e largely significant. Combined treatments were not better than the in dividual applications.
