Management of grain discoloration of rice.

Abstract

During 1991 and 1992 rice cv. Pankaj were treated with carbendazim, edifenphos, mancozeb, propiconazole and salt in field tests in Assam, India. The fungi associated with rice grains were Curvularia lunata [Cochliobolus lunatus], Curvularia pallescens [Cochliobolus pallescens], Curvularia geniculata [Cochliobolus geniculatus], Curvularia eragrostidis [Cochliobolus eragrostidis], Drechslera oryzae [Cochliobolus miyabeanus], Fusarium moniliforme [Gibberella fujikuroi], Nigrospora oryzae [Khuskia oryzae], Trichonoconis padwickii [Alternaria padwickii] and Trichothecium roseum. The most effective disease control was given by fungicide at the boot leaf stage followed by salt 20 days after 50% flowering. The best control was given by mancozeb and propiconazole.
