Inoculation of leaf discs of Hevea by an isolate of Microcyclus ulei incompatible to a Hevea clone induced resistance to subsequent infection by a compatible race. Simultaneous inoculation of compatible and incompatible races reduced the size of lesions but not their numbers. Inoculation of an incompatible race 24 h prior to inoculation of a compatible race reduced both the number and size of lesions. The reduction was proportional to the concentration of the incompatible race inoculum. On intact leaves inoculation of a compatible race prior to an incompatible race reduced the number of lesions and the conidia produced

Abstract

Inoculation of leaf discs of Hevea by an isolate of Microcyclus ulei incompatible to a Hevea clone induced resistance to subsequent infection by a compatible race. Simultaneous inoculation of compatible and incompatible races reduced the size of lesions but not their numbers. Inoculation of an incompatible race 24 h prior to inoculation of a compatible race reduced both the number and size of lesions. The reduction was proportional to the concentration of the incompatible race inoculum. On intact leaves inoculation of a compatible race prior to an incompatible race reduced the number of lesions and the conidia produced
