Use of Native Microorganisms and Commonly Recommended Fungicides in Integrated Management of Rice Seed Borne Pathogens

Fungal biocontrol agents isolated from rice ecosystem were able to tolerate captan and thiram at 1000 ppm, while were completely inhibited by carbendazim. Integration of biocontrol agents and commonly used fungicides showed positive association by reducing the seed infection compared to fungal antagonists individually. Aspergillus fumigatus showed highest tolerance to thiram when compared to other biocontrol fungi, while Trichoderma viride showed highest tolerance to captan. The integration did not affect either germination or seedling vigour index adversely.
