Abstract

Rubber plant are plantation crops that grow in various parts of Indonesia. Almost all parts of the plant will be the target of infection from plant diseases, one of which is the rubber leaf fall disease Pestalotiopsis sp. Disease control from rubber leaf fall of Pestalotiosis sp. environmentally friendly by using botanical pesticides derived from plant extracts. The purpose of this study was to determine the effectiveness of extracts from galangal (Alpinia galanga), citronella leaves (Cymbopogon nardus), and turmeric (Curcuma longa), as vegetable fungicides used for alternative control of rubber leaf fall disease. This study used a Randomized Block Design (RAK) which consisted of 7 replications. Parameters observed were incubation period, intensity of attack, percentage of attack, number of spots and number of fallen leaves. Based on the results of the study, it showed that from several extracts used, namely galangal, extract, citronella leaf rxtract and turmeric extract which had the potential to inhibit the growth of Pestalotiopsis sp. in controlling rubber leaf fall disease, namely galangal extract, because galangal has an active compound of volatile oil that can inhibit the growth of pathogenic fungi.
