Effect of animal excreta on mycelial growth of Pyricularia oryzae

Abstract

Rice, Oryza sativa, which is the most widely consumed staple food among world’s human population. Rice blast disease caused by the fungus known as Pyricularia oryzae, has become an important and serious disease worldwide. Combination of animal excrements showed increased fungicidal activity against pathogens of several crops. Combination of cow urine with sheep, goat and buffalo urine gave complete inhibition of the mycelial growth of P. oryzae. The combination of dung and urine of buffalo and goat recorded total inhibition of the mycelial growth of P. oryzae. Combination of animal excrements showed no loss in the fungitoxic nature. Hence sheep, buffalo, goat, cow urine and hen litter shows effective control against P. oryzae in this experiment.
