IN VITRO EVALUATION OF BOTANICALS AND PANCHAGAVYA AGAINST LEAF BLAST FUNGUS PYRICULARIA GRISEA
Abstract
Rice blast caused by Pyricularia grisea cav. continues to be a major constraint in rice production. Since, the existing chemical control measures being costly and may favour development of resistance in pathogens, the potential alternative methods have been explored in the present studies. Five plant parts extract namely Neem seed kernel extract, Neem oil, Asafoetida spp. and Pongamia spp. extracts and Panchagavya, were evaluated for their efficacy against blast of rice in in vitro conditions. The results concluded that the Neem seed kernel showed a significantly more mean suppression value.  Â
