Management of rice blast disease caused by Pyricularia oryzae through application of biocontrol agents and fungicides alone and in possible combinations

Rice blast caused by Pyricularia oryzae is considered as a major disease because of its wide geographic distribution and destructiveness under favourable conditions causing serious yield losses. The present study was undertaken to manage this disease under field conditions. Therefore, in vitro evaluation of biocontrol agents and fungicides against P. oryzae was done under laboratory conditions and a field experiment was conducted to evaluate the efficacy of bio-control agents viz., T. harzianum and T. viride and fungicides viz., tricyclazole and tebuconazole 50
