Abstract
Currently, Pestalotiopsis leaf fall disease caused by the fungus Pestalotiopsis microspora is commonly found in Indonesian rubber plantations. The rubber defoliation period usually occurs for 1 month as a response to drought during the dry season. However, due to this disease, the rubber defoliation period occurs gradually with an earlier fall. Leaf fall can cause a decrease in the number of plant canopy which affects the leaf area index and latex production. Therefore, this study was carried out to examine the effect of Pestalotiopsis leaf fall disease on the decrease in leaf area index and latex production. The study was carried out at the Experimental Garden of the Indonesian Rubber Research Institute, Sembawa, South Sumatra by observing disease severity in RRIC 100 and GT 1 clones, measuring leaf area index, and observing latex production for 1 year. The results showed that there was a strong correlation between an increase in the Pestalotiopsis leaf fall disease severity and a decrease in leaf area index. In addition, the decrease in leaf area index affects the decrease in latex production.
