Banana is the most favorite fruits in the world. Indonesia is in the center of origin and diversity of banana in Southeast Asia. Banten is one of the most banana producer in Indonesia. However, no information on banana diversity and its associated disease available from this province. In this paper, we explored Kabupaten Pandeglang in its diversity of banana and its associated disease. Eleven local banana germplasm were identified with their associated disease. Fusarium wilt, Sigatoka, and Blood disease are the most common diseases found on those varieties. Seven local banana germplasm are described in this paper. These information are very important to preserved biodiversity of Indonesia and will be useful for future food security and sustainability.

Abstract A description is provided for Fusarium udum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cajanus cajan. DISEASE: Fusarium wilt of pigeon pea, characterized by withering and drying up of green parts as if from drought. GEOGRAPHICAL DISTRIBUTION: India; the disease is soil-borne and restricted to the parts of India where the crop is grown. TRANSMISSION: A soil-borne disease but also transmitted on roots (Subramanian, 1971).

Uji Toksisitas Beberapa Fungisida Nabati terhadap Penyakit Layu Fusarium (Fusarium oxysporum) pada Tanaman Kentang (Solanum tuberosum L.) secara In Vitro (Toxicity Test of several Biofungicides in controlling Fusarium wilt (Fusarium oxysporum) in Potato Plants (Solanum tuberosum L.) by In Vitro) Ghea Dotulong1*), Stella Umboh1), Johanis Pelealu1), 1) Program Studi Biologi, FMIPA Universitas Sam Ratulangi, Manado 95115*Email korespondensi: [email protected] Diterima 9 Juli 2019, diterima untuk dipublikasi 10 Agustus 2019 Abstrak Tanaman kentang (Solanum tuberosum L.) adalah salah satu tanaman hortikultura yang sering mengalami penurunan dari segi produksi dan produktivitasnya, akibat adanya serangan penyakit layu yang salah satunya disebabkan oleh Fusarium oxysporum. Tujuan penelitian ini adalah mengidentifikasi toksisitas beberapa fungisida nabati dalam mengendalikan penyakit Layu Fusarium (F. oxysporum) pada tanaman kentang (Solanum tuberosum L.) secara In Vitro. Metode Penelitian yang digunakan yaitu metode umpan beracun. Data dianalisis dengan Rancangan Acak Lengkap (RAL) dengan Analisis Varian (ANAVA) yang dilanjutkan dengan menggunakan metode BNT (Beda Nyata Terkecil). Hasil Penelitian, diperoleh nilai toksisitas fungisida nabati tertinggi yaitu pada ekstrak daun sirsak dengan nilai HR (69,44%), kategori berpengaruh, ditandai dengan diameter koloni 2,75 cm (100ppm) dan yang terendah toksisitasnya yaitu pada ekstrak daun jeruk purut dengan nilai HR (49,81%), kategori cukup berpengaruh ditandai dengan diameter koloni 3,75 cm (25ppm). Semakin tinggi konsentrasi yang diujikan maka semakin tinggi toksisitas dari fungisida nabati yang diberikan.Kata Kunci: fungisida nabati, Fusarium oxysporum, tanaman kentang, In Vitro Abstract Potato plants (Solanum tuberosum L.) is one of the horticulture plants which often decreases in terms of production and productivity, due to the attack of wilt, one of which is caused by Fusarium oxysporum. The purpose of this study was to determine the toxicity of several biofungicides in controlling Fusarium wilt (F. oxysporum) in potato plants (Solanum tuberosum L.) in Vitro. The research method used was the In Vitro method with the poison bait method. Data were analyzed by Completely Randomized Design with Variant Analysis (ANAVA), followed by the BNT method. The results showed that the highest biofungicide toxicity value was soursop leaf extract with HR values (69.44%), influential categories, characterized by colony diameter 2.75 cm (100ppm) and the lowest toxicity, namely in kaffir lime leaf extract with a value of HR (49.81%), quite influential category was characterized by colony diameter of 3.75 cm (25ppm). The higher the concentration tested, the higher the toxicity of the biofungicide given.Keywords: biofungicides, Fusarium oxysporum, Potato Plants, In Vitro.
