The results of some botanicals and micro-nutrients tested against Macrophomina leaf blight and its causal agent under in vitro conditions indicated that the extracts of Adenocalymma alliaceum and Allium spp. (20%) completely inhibited the growth of fungus in agar-well diffusion method. The growth of M. phaseolina was inhibited by 77.2 and 74.7 per cents with extracts of A. alliaceum and Allium spp., respectively and by 80.3% in zinc sulphate amended medium (1000 ppm) as against the control, which recorded 89.0 mm mycelial growth. The spray combination of the effective treatments under pot culture studies viz., Mancozeb (0.2%) + Allium spp. (10%), Mancozeb (0.2%) + Zinc sulphate (0.5%), Allium spp. (10%) + Zinc sulphate (0.5%) were significantly superior and respectively recorded 94.1, 90.6 and 88.2 per cents disease reduction over the control in green house.
