    Abstract

    ABSTRACT Cowpea mosaic disease caused by the virus is one of the main problems the cultivation of beans. Control of this disease is difficult because there has been no resistant cultivars available commercially, the virus can be transmitted by an insect vector and has been known to seed-borne. Hence, increased resilience by induction of systemic resistance is needed to control this disease. This study aimed to evaluate the ability of bougainvillea extract to control the disease in the long bean mosaic through the induction of plant resistance. This study used a completely randomized design with 2 factors, namely the concentration of the extract and the time interval of virus inoculation. Parameter observations include the incubation period, the intensity of the disease, weight of fresh pod and weight of dry straw. The data was analyzed using Fisher test at 5% level and DMRT (Duncan`s Multiple Range Test) at 5% level. The results showed that the bougainvillea extract treatment, concentrations of virus inoculation and the time interval could prolong the incubation period, lower the intensity of the disease, and indirectly increase the weight of fresh pod and weight of dry straw through a reduction in the intensity of the disease. Keywords: consentration, time interval, incubation period, disease intensity
