      Abstract
      Jamur Fusarium oxysporum pada tanaman vanili menyebabkan penyakit busuk batang vanili. Patogen ini menyebar pada jaringan yang terluka dan merusak mekanisme penyaluran air dan zat hara ke seluruh vanili sehingga menurunkan produktivitas. Penerapan pestisida nabati dalam bentuk coating menggunakan bahan minyak serai wangi dapat menghambat laju pertumbuhan jamur F.oxysporum. Penelitian ini secara umum bertujuan untuk menguji teknik yang tepat dalam mengaplikasikan larutan coating serai wangi pada bibit vanili. Secara khusus penelitian ini bertujuan untuk menganalisis tingkatserangan jamur terhadap teknik pengaplikasian dan konsentrasi larutan pestisida pada batang bibit vanili secara in vivo, dan menentukan teknik coating yang tepat diterapkan pada batang bibit vanili yang terluka. Penelitian dimulai dengan membuat larutan coating dengan komposisi parafin 10% dan minyak serai wangi 12%, kemudian diterapkan pada bibit vanili dengan teknik pengaplikasian oles dan semprot. Serta konsentrasi larutan coating murni (100%) dan campuran (50%). Pemilihan teknik pengaplikasian dan konsentrasi larutan coating berdasarkan tingkat serangan jamur. Formulasi pengaplikasian larutan coating yang dihasilkan adalah Brush-Murni (BM), Brush-Campuran (BC), Sprayer-Murni (SM), dan Sprayer-Campuran (SC). BC memiliki tingkat pertumbuhan jamur terkecil di polybag dan di botol sebesar 12,49 mm dan 0,28 mm. Pertumbuhan jamur terkecil di lahan 0,58 mm dengan penerapan BM.
       
      Fusarium oxysporum fungus on stem cuttings of vanilla plants causes vanilla stem rot disease. This pathogen spreads in injured tissues and damages the mechanism of delivering water and nutrients throughout vanilla, thereby reducing productivity. The application of vegetable pesticides in the form of coatings using citronella oil ingredients can inhibit the growth rate of F.oxysporum fungi. This study generally aims to test the right technique in applying citronella coating solution to vanilla seedlings. In particular, this study aims to analyze the level of fungal infestation against the application technique and concentration of pesticide solutions on the stems of vanilla seedlings in vivo, and determine the appropriate coating technique applied to the stems of injured vanilla seedlings. The research began by making a coating solution with a composition of 10% paraffin and 12% citronella oil, then applied to vanilla seedlings with a smear and spray application technique. As well as the concentration of pure (100%) and mixed (50%) coating solutions. Selection of application technique and concentration of coating solution based on the degree of fungal attack. The resulting coating solution application formulations are Brush-Pure (BM), Brush-Blend (BC), Sprayer-Pure (SM), and Sprayer-Mixture (SC). BC has the smallest mushroom growth rate in polybags and bottles of 12.49 mm and 0.28 mm. The smallest fungal growth in the field is 0.58 mm with the application of BM.
