UJI VIRULENSI Colletotrichum Scovillei ASAL KABUPATEN MAGELANG PADA BEBERAPA VARIETAS TANAMAN CABAI SECARA IN VIVO

Virulence assay is an essential step to determine the severity of pathogen infection. The virulence assay of Colletotrichum scovillei originating from Magelang Regency was conducted on several chili varieties, namely OR Twist 42, Mahkota, and Pillar F1. This study investigated the virulence of Colletotrichum scovillei on different chili varieties through in vivo inoculation. The experiment was conducted from July to October 2024 at Bandongan Teaching Farm greenhouse, Drojogan, Bandongan District, Magelang Regency (altitude: 431 m above sea level). A completely randomized block design with single factor and four replications was employed. Data were analyzed using analysis of variance followed by 1% BNT test. Colletotrichum scovillei inoculation significantly affected leaf count, incubation period, disease incidence, disease severity, and fruit weight parameters, but not plant height. Characteristic anthracnose symptoms appeared as irregular brown lesions with dark margins on leaf surfaces. Disease incidence remained at mild levels across all varieties, with Mahkota showing the highest infection rate(2.03%), followed by Pillar F1 (1.85%) and OR Twist 42 (1.79%). All varieties showed mild disease severity OR Twist 42 (0.19%), Mahkota (0.24%), and Pillar F1 (0.23%).
