Abstract:
A number of new and commercially available fungicides were evaluated against sheath blight of rice at Regional Research
and Technology Transfer Station, Chiplima, Sambalpur, Odisha. Under , 100 per cent inhibition of mycelial growth
of was observed with the fungicide (Trifloxystrobin + Tebuconazole) at 200 ppm concentration.
Besides, it also had the lowest value of 3.19 μg ml . Under , the pooled data of two consecutive season
indicated that, all the fungicides were effective in controlling the disease as compared to control but three spraying with
(Trifloxystrobin + Tebuconazole) @ 0.4 g l at 15 days interval resulted in least sheath blight disease severity (5.0% PDI)
as compared to untreated control (41.85% PDI). It was at par with the standard fungicide Propiconazole @ 1ml l (6.11 %
PDI) with the highest yield of 51.9 q ha .
