ABSTRACT
Twenty fungicides, six bioagents, six botanicals and five ITK’s were evaluated against blast of pearl millet caused by Pyricularia grisea. Among the non-systemic fungicides evaluated mancozeb 75% WP inhibited cent percent mycelial growth of the pathogen, in systemic fungicides tricyclazole 75%WP (100%) gave maximum inhibition of the mycelial growth of the pathogen. followed by difenconazole 25% EC (94%), hexaconozole 5E (93%) and propiconazole 25% EC (88%). SAAF (Carbendazim+ Mancozeb) @ 0.05% and Nativo (Tebuconazole50% + Trifloxystrobin 25%) among combi product fungicides gave maximum inhibition (100%) of the mycelia growth of the pathogen. Among the bioagents Trichoderma harzianum + Bacillus subtilis (93%) followed by Trichoderma harzianum + Pseudomonas fluorescens (90%) gave maximum inhibition. Among commercially available botanicals evaluated, Agro neem (75%) gave maximum inhibition followed by Neem gold (58%). ITKs at 5 per cent concentration, maximum inhibition was noticed in panchagavy (75%) followed by butter milk (58%). Significantly least inhibition was noticed in cow milk (40%). Hence these effective fungicides, bioagents, botanicals and ITKs can be used as one of the component in the Integrated Management of blast of pearl millet.
