      Abstract

      The objectives of the research was to evaluate relathionship between airborne condia and severity of colettotrichum leaf fall diseases on five rubber clon experimental at BPP Sembawa. The study was carried out in rubber nursery at BPP Sembawa. The study was field studies. In this study air borne conidia was trap using spora trap which were placed on every rubber tree early in the morning and to be taken tomorow morning. The severity of collethotrichum leaf fall diseases was observed every week. Result of the study showed that there was the relationship between amount of airborne conidia to the severity of collethotrichum leaf fall diseases. The highes airbone conidia was traped the highes disease severity. Clon 85/8 was very susceptible clon to collethotrichum wheres the severity reach 91.60 percent, while the lowest was clon 85/3 was 49.4 percent.
