Abstract (AB)Disease surveys were conducted in Rodrigues between 1980 and 1998 to determine the level of infection by various pathogens in maize. Smut(Sphacelotheca reiliana) was not encountered. Maize stripe virus was insignificant, although the vector Perigrinus maidis was present in most maize plantations. The incidence of rust (Puccinia sorghi) was low over the island. Leaf blight (Helminthosporium turcicum) and rust (Puccinia polysora) were light to moderate in some cultivars only. However the two diseases have the potential of reaching epidemic proportions under favourable conditions in susceptible varieties. Maize streak virus (MSV) was the most important disease encountered reaching levels as high as 100
