dc.description.abstractWhite root disease (JAP) is an important disease that attacks on rubber plants caused by the Rigodoporus lignosus on the roots of rubber plants which can cause leaves to turn yellow, fall, and the stems to dry and decay and even die on plants. Disease control using biologl agents in the form of antagonist Trichoderma virens has the potential to prevent or suppress the development of JAP disease in rubber plant seeds. This research was conducted in April to July 2019 at the Pathology, Entomology, Microbiology Laboratory of the Faculty of Agriculture and Animal Husbandry, Sultan Syarif Kasim Riau Islamic University. The experiment used a non factorial complete randomized design (RAL) of six treatments and five replications in which Trichoderma virens was applied 7 days before the pathogen infection, while the treatments were 0 g, 25 g, 50 g, 75 g, 100 g, and 125 g. The results showed that the concentration of Trichoderma virens was effective in suppressing the Rigodoporus lignosus attack at a dose of 125 g by 100% in rubber plant nurseries and was able to increase the percentage of plant height increase by 35.39%en_US
