Abstract. Kurnia TD, Purwantoro A, Sulandari S, Basunanda P, Setiawan AB, Fatmawati Y, Andika IP. 2022. Molecular and morpho-physiological identification of yellow leaf curl disease cucumber in Salatiga, Indonesia. Biodiversitas 23: 1466-1474. Plant viruses are a limiting factor Indonesian production. However, because numerous generate identical symptoms on infected plants across cultivars, identify the virus discovered field. The management diseases is dependent accurately identifying associated with certain among cultivars evaluating possible insect vectors. Because there have been several reports cucumbers, generating resistant phenotypic physiological disorders, probable vectors all important aspects plant management. This study aimed to determine putative its symptoms, including morphology physiology disorders cultivars. Common found included curling, spots, malformed shapes, mortality from severely infested leaves, yellowing, occurrences varying Curling spots were >70% samples tested Virus infection affected agronomic features fruit characteristics differently depending detection confirmed that polerovirus insects also carried Polerovirus. provides initial information monitoring various stages curling potential this will later be useful synthesize effective practice future.
