The research was done by observing the spreading of yellow leaf curl disease on chilli pepper plants in Kayangan district, North Lombok Region West Nusa Tenggara Province. The objectives of work to determine the spreading of Yellow Leaf Curl Disease on chilli pepper and evaluation of disease control practice done by chilli pepper farmers. Observations were conducted in farmer’s chilli pepper field during plantation season weekly. The disease intensity and it’s infection rate were determined by counting the number of plants showing symptoms in each plot. The result showed that infected plant showed leaf curl symptom, chlorosis, dense, and retarding growth. The disease intensity reached 80-100%. All plant showed a high positive correlations between the infection rate to the vector insects. The result of molecular identification using PCR are detected the Begomovirus existence on plant with the amplification product sized 580bp.
