Abstract
Rice leaf scald is caused by the fungal pathogen Monographella albescens (Thüm) Parkinson, Sivanesan and Booth (anamorph Gerlachia oryzae (Hashioka and Yokogi) W. Gams). It is a disease that can be found throughout virtually all of the rice growing regions of the world (International Mycological Institute, 1996). Under favourable climatic and cultural conditions, M. albescens can pose a serious threat to rice production and is often ranked in the first three or four fungal constraints for a region, along with blast (Magnaporthe grisea), sheath blight (Rhizoctonia spp.) and brown spot (Helminthosporium oryzae) (Jones et al., 1991; Alam et al.,1985; Cuevas-Perez and Gaona, 1988; Kempf, 1983; Prabhu and Sitarama-Prabhu, 1989). Incidence of infection in an area can reach high levels under favourable conditions, resulting in significant loss of yield, such as the 23.4% yield reduction reported in India by Srinivasan (1981).
