Abstract:
Rice blast disease, caused by the fungal pathogen Magnaporthe oryzae, is one of the most damaging plant diseases worldwide. Use of chemicals is an important tool to control rice blast disease. Therefore, a new combination molecule of Filia 52.5 SE (Tricyclazole 34.2% + Propiconazole 10.7%) was tried against leaf and neck blast of rice under field condition. The results from first and second season trial revealed that, Filia 52.5 SE @ 1.5 ml/lit was highly effective against Rice leaf blast, which recorded 79.89 per cent control over untreated check at par with Filia 52.5 SE @ 1.25 ml/lit (79.07%). This was followed by Filia 52.5 SE @ 1.0 ml/lit (72.80%), Tricyclozole 75 WP @ 0.8 g/lit (71.02%). Untreated check recorded a PDI of 25.56 at 15 days after 2nd spray. Similarly, the second season also, Filia 52.5 SE @ 1.5 ml/lit was highly effective against Rice leaf blast, which recorded 79.89 per cent control over untreated check at par with Filia 52.5 SE @ 1.25 ml/lit (79.07%). This was followed by Filia 52.5 SE @ 1.0 ml/lit (72.80%), Tricyclozole 75 WP @ 0.8 g/lit (71.02%). In both seasons, the control of neck blast also, similar trend was exhibited among the various treatments and Filia 52.5 SE @ 1.5 ml/lit and 1.25 ml/lit were very effective and at par with each other in checking neck blast. 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.
