Abstract:
Sheath blight (<em>Rhizoctonia solani</em>) is one of the most devastating diseases of rice. In recent years, resistance development in pathogens a new constraint has emerged due to repeated fungicide usage with single mode of action. Therefore, A new combination molecule of Filia 52.5 SE (Tricyclazole 34.2% + Propiconazole 10.7%) was tried against sheath blight of rice under field condition. The results from first and second season trial revealed that all the doses of Filia 52.5 SE were very effective against rice sheath blight disease. In first season, the disease incidence ranges from 7.75 to 8.12 PDI in Filia 52.5 SE treatments at 15 days after 2<sup>nd</sup> spray. Among the various treatments, Filia 52.5 SE @ 1.5 ml/lit recorded the least PDI of 7.75 at par with Filia 52.5 SE @ 1.25 ml/lit (7.83 PDI) and Filia 52.5 SE @ 1.0 ml/lit (8.12 PDI). Whereas untreated control plots recorded 28.50 PDI at 15 days after 2<sup>nd</sup> spray. Similarly, the second season trial result revealed that, the disease incidence ranges from 3.50 to 4.45 PDI in Filia 52.5 SE treatments at 15 days after 2<sup>nd</sup> spray. Among the various treatments, Filia 52.5 SE @ 1.5 ml/lit recorded the least PDI of 3.50 at par with Filia 52.5 SE @ 1.25 ml/lit (3.63 PDI) and Filia 52.5 SE @ 1.0 ml/lit (4.45 PDI) followed by Propiconazole 25 EC @ 1.0 ml/lit (6.16 PDI), Tebuconazole 50% + Trifloxystrobin 25% WG @ 0.4 g/lit (6.40 PDI), Tricyclozole 75 WP @ 0.8 g/lit (15.0 PDI) and Kitazine 48 EC @ 2.0 ml/lit (17.8 PDI) whereas untreated control plots recorded 21.20 PDI at 15 days after 2<sup>nd</sup> spray. Filia 52.5 SE at 1.5 and 1.25 ml/lit recorded significantly higher grain yields, which were on par with each other and followed by Filia 52.5 SE @ 1.0 ml/lit in both seasons.
