Biointensive Control of Begomovirus in Big Red Chili Plants (Capsicum annuum L) Based on Barrier Plants in Southeast Sulawesi. Begomovirus is a disease-causing agent from the plant virus group. This disease is one of the inhibiting factors for chili cultivation in various countries and regions in Indonesia. If chili plants are infected when they are still young, it can cause yield loss and crop failure. The spread of Begomovirus in the field is determined by whitefly insects. Controlling the population of vector insects is important to reduce infected plants. Barriers around chili plants can be used as vector barriers in the field. The purpose of this study was to evaluate the control of Begomovirus on large red chili peppers using the Biointensive barrier plant model. The method used was Randomized Block Design (RAK), analysis of variance and further BNT test with a confidence level of 95%. Observation variables included: symptoms, incidence and severity of Begomovirus disease, whitefly population and growth and production of chili. The results showed that the biotic barrier planting pattern of kenikir flowers affected the decrease in the whitefly insect population, incidence and severity (PepYLCIV) and increased red chili production. The lowest whitefly population was 0.45 individuals/plant compared to the control of 1.08 individuals/plant, the lowest incidence and severity (PepYLCIV) were 45% and 1.33% with the highest chili production (1.14 kg-plot) compared to the control (0.31 kg-plot).

Virus gemini penyebab penyakit keriting daun kuning pada tanaman cabai dikenal dengan Pepper yellow leaf curl virus. Infeksi virus mengakibatkan kerusakan morfologi seperti, malformasi daun, daun kecil, leaf cupping, dan tanaman kerdil. Bukan hanya gangguan morfologi tetapi juga gangguan fisiologi seperti kandungan nitrogen dan klorofil daun tanaman cabai. Seiring dengan perkembangan teknologi digital maka penilaian keparahan gejala, pengukuran kandungan klorofil dan nitrogen dan luas daun terinfeksi virus gemini dapat dilakukan dengan teknik spektral biosensor. Metode ini merekam reflektansi cahaya merah, hijau, dan biru (Red, Green, Blue/RGB) dari objek tanaman cabai. Tujuan penelitian adalah mengukur kandungan nitrogen dan klorofil tanaman cabai terinfeksi virus gemini dan luas daun terinfeksi virus gemini. Metode yang digunakan untuk mengukur reflektansi RGB adalah spektral biosensir dengan menggunakan software ImageJ processing. Pengambilan sampel tanaman cabai terinfeksi virus gemini ditentukan secara acak berdasarkan gejala pada pertanaman cabai di pulau Muna dan Buton. Variabel yang digunakan adalah gejala dan keparahan gejala virus gemini, kandungan nitrogen dan klorofil tanaman cabai terinfeksi virus gemini, luas daun terinfeksi virus gemini. Analisis data dilakukan secara deskriptif. Hasil penelitian menggunakan metode citra digital software ImageJ menunjukkan bahwa gejala bervariasi berpengaruh pada keparahan gejala tertinggi Lakanaha sebesar 95,56%, dan rendah Suka Damai sebesar 33,33%. Kandungan nitrogen meningkat Suka Damai sebesar 49,90 dan rendah Lambiku 10,42, Kandungan klorofil tertinggi Pentiro sebesar 24,21 dan rendah Lakanaha sebesar 1,12. Luas daun tertinggi Pentiro sebesar 4,727 cm2, dan rendah Labukolo 1,243 cm2.
