Abstract:
Small millets comprising of finger millet (Eleusine coracana), kodo millet (Paspalum scrobiculatum), foxtail millet (Setaria italica), little millet (Panicum sumatrense), barnyard millet (Echinochloa frumentacea) and proso millet (Panicum miliaceum) are the poor man’s food that ensures nutritional security to the people living in harsh and difficult terrains. Though the crop is less prone to diseases and pests but under vulnerable condition, blast caused by Pyricularia grisea (Cooke) Sacc. Telemorph of a heterothallic ascomycetes, Magnaporthe grisea (Hebert) Barr. [Anamorph:] had wide host range of Gramineae and took heavy toll of the crop in various ecological zones. To study the pathogenic variability of isolates of P.grisea cross inoculation test were carried out on their respective host plant viz., finger millet, foxtail millet, proso millet and little millet. The studies revealed that all isolates Pg1, Pg2, Pg3 and Pg4 were found to be pathogenic in their own host. The isolate of Finger millet (Pg1) and isolate of Foxtail millet (Pg4) were found to be cross infective with each other whereas, the isolate of proso millet (Pg3) and little millet (Pg2) were non-infective on other hosts. Among botanicals the extracts of onion (Allium cepa), garlic (Allium sativum L.), neem (Azadirachta indica L.) amla (Emblica officinalis), teenpatia (Oxalis latifolia), babool (Vachellia nilotica) and herbal plant extract (Zuki) when used against P.grisea by poisoned food technique, only the herbal plant extract (Zuki) inhibited the maximum mycelial growth of all the test pathogens at 5& 10 % conc
