Among the eco-friendly products tested viz., leaf extracts of eucalyptus and henna @ (25% conc.), Sheep urine @ (10%), goat urine @ (20%) and Pseudomonas fluorescens @ (10g/kg of seed) alone and in combination, seeds treated with sheep urine was found to increase the germination percentage, vigour index and also enhance the yield parameters of rice. Among the different ecofriendly products, seeds treated with P. fluorescens retained the fungitoxicty for the longest duration of time against P. oryzae. Finally, under the pot culture studies, seed treatment with P. fluorescens and foliar spray with sheep urine on 30 and 50 DAT recorded the least leaf blast intensity in rice.
