Determination of yield losses against sheath rot caused by Sarocladium oryzae in rice varieties with differential resistance.

ABSTRACT: Sheath rot (Sarocladium oryzae) of rice causes significant grain yield losses, warranting integrated, cost effective and eco-friendly management. With limited availability of highly resistant varieties, combining resistant / moderately resistant varieties with judicious and need based application of fungicides is a practical alternative. However, scarce information is available on the extent of yield losses in varieties with varied levels of resistance. This study evaluated yield losses in terms of 1000 grain weight (TGW) in rice varieties with varying resistance levels to sheath rot under protected conditions using fungicide azoxystrobin (11%) + tebuconazole (13.8%). It was observed that the differences in disease severity, AUDPC values and TGW loss were mainly attributed to the interacti
