Abstract

Identifying symptoms of P. capsici pathogen attack that causes stem rot disease in pepper seedlings is an indispensable first step to determining the type and technique of disease prevention and effective control in the supply of healthy pepper seedlings. This study aimed to determine the occurrence of P. capsici attack symptoms in pepper seedlings. The pepper used was the Bengkayang variety using 2 segments of cuttings from the climbing vines of a healthy parent tree. The research was conducted at the UPSBP office in West Kalimantan Province and the Laboratory of Plant Diseases, Faculty of Agriculture, University of Tanjungpura. The source of the pathogenic inoculum that causes stem rot of pepper was taken from the rhizosphere of plants with symptoms of stem rot. The soil containing the pathogens was seized, put in polybags, and planted with healthy pepper cuttings and leaves. The results showed that there were 3 types of symptoms caused by P. capsici attack, namely symptoms on the leaves with black spots appearing that could cause necrosis and cause leaf fall, on the shoots/shoots that could cause the nodes to break off, and on the base of the stem/roots can cause plant death.Keywords: pepper seedlings, Phytophthora capsici,  stem rot disease INTISARIIdentifikasi gejala serangan patogen P. capsici penyebab terjadinya penyakit busuk pangkal batang pada bibit lada merupakan langkah awal yang sangat diperlukan untuk menentukan jenis dan teknik pencegahan serangan penyakit serta pengendalian yang efektif dalam penyediaan bibit lada yang sehat. Tujuan penelitian untuk mengetahui terjadinya gejala serangan P. capsici  pada bibit tanaman lada. Lada yang digunakan adalah varietas Bengkayang dengan menggunakan 2 ruas stek dari sulur panjat pohon induk yang sehat. Penelitian dilaksanakan di kantor UPSBP Provinsi Kalimantan Barat dan Laboratorium Penyakit Tanaman Fakultas Pertanian Universitas Tanjungpura. Sumber inokulum patogen penyebab busuk pangkal batang lada di ambil dari rizosfer tanaman bergejala busuk pangkal batang. Tanah yang mengandung patogen diambil, dimasukkan ke dalam polibeg dan ditanami dengan setek batang dan daun lada yang sehat. Hasil penelitian menunjukkan bahwa terdapat 3 jenis gejala yang ditimbulkan akibat serangan P. capsici yaitu gejala pada bagian daun dengan muncul bintik hitam yang dapat menyebabkan nekrosis dan menyebabkan daun gugur, bagian tunas/pucuk yang dapat menyebabkan putusnya pucuk tanaman, dan bagian pangkal batang/akar dapat menyebabkan kematian tanaman. Kata Kunci: bibit lada, busuk pangkal batang, Phytophthora capsici
