Efficacy of fungicides in controlling rice blast and dirty panicle diseases in Thailand.

ABSTRACT: In this study, the fungicidal activities of the fungicides azoxystrobin, difenoconazole + propiconazole, carbendazim, flutriafol, fluopyram + tebuconazole, mancozeb and thiophanate-methyl against rice blast and dirty panicle pathogens were evaluated under laboratory and field conditions. Mancozeb exhibited the highest level of fungicidal activity against the blast pathogen Pyricularia oryzae, with an EC₅₀ value of 0.25 parts per million (ppm). The combination of two fungicides, fluopyram + tebuconazole, showed the strongest fungicidal effect against Bipolaris oryzae and Curvularia lunata, with EC₅₀ values of 0.587 ppm and 0.435 ppm, respectively. Meanwhile, carbendazim and flutriafol demonstrated the best level of fungicidal activity against Fusarium incarnatum, with
