Abstract

Fusarium wilt disease caused by Fusarium oxysporum fsp. cubense is the most important and destructive disease on banana. The pathogen is soil-borne and can survive in soil without the occurence of the host. The Vesicular Arbuscular Mychorriza (VAM) is a symbiotic associated fungi and plant roots. The VAM which infected plant can induce the resistance to pathogen. Banana seedlings obtained from tissue culture one free from pathogen. The seedling was inoculated with VAM to induce the resistance to Fusarium wilt disease. The result showed that the seedling inoculated with VAM can reduce diseases intensity of Fusarium wilt on banana.

Abstract

The role of salicylic acid on host-pathogen interactions of sweet potato scab disease (E. batatas) was done by measuring (1) the level of resistance of sweet potato cultivars to scab disease, (2) salicylic acid content in sweet potato leaves before inoculation, 3 days, 6 days, and 9 days after inoculation, and (3) effect of salicylic acid to the germination of E. batatas conidia. The result showed that there were different responses of sweet potato cultivars to pathogens infection. Inoculation with E. batatas isolate from Wonosobo (WO2) showed resistant reaction on Muaratakus, moderate resistant on Cangkuang, moderate susceptible on Malothok, and susceptible on Mlg 12549. Resistant cultivar (Muaratakus) has higher salicylic acid content than moderate resistant (Cangkuang), moderate susceptible (Malothok), and susceptible cultivar (Mlg 12549). Salicylic acid inhibited germination of E. batatas conidia.

Abstract

Colletotrichum sp. is an important pathogen on pepper and caused losses up to 50-100% in rainy season. The objectives of this study is to examine the ability of Curxanil 8/64WP (mixed fungicides between cymoxanil and mancozeb 8/64) in controlling Colletotrichum sp., and to know the resistance of the pathogen against fungicides in vitro. Field experiment was arranged in Complete Randomized Block Design with five treatments i. e. 0, 0.1, 0.2, 0.3, and 0.4% of each tested fungicide, compared with 0.2% mancozeb, with four replications. Fungicides toxicity were tested in vitro using Poisoned Food Technique. This experiment was arranged in Complete Randomized Design with eight treatments i.e. 0, 50, 100, 200, 800, 1000, 1500, 2000 ppm of mancozeb, cymoxanil, and curxanil with four replications. Fungicides resistance assay of Colletotrichum sp. against Curxanil was tested using the same method with gradually increasing fungicide concentrations.The results showed that in the field, anthracnose disease of red pepper can be controlled with 0.2% Curxanil. In vitro test showed that mancozeb at 800 ppm inhibited 98.8% colony diameter of Colletotrichum sp., while cymoxanil at 2000 ppm only reduced 37.2%. Colletotrichum sp. treated with gradually increasing concentration of Curxanil showed that its colony diameter could not be reduced and still grew 52.6% compared with one time treatment. This showed that Colletotrichum sp. had a potency to be resistant against cymoxanil. This problem can be avoided by mixing cymoxanil and mancozeb fungicides.  Colletotrichum sp. adalah jamur patogen penting pada cabai merah. Kehilangan hasil mencapai 50-100% pada musim hujan. Pengendalian yang selama ini dilakukan adalah dengan fungisida. Penelitian dilakukan untuk menguji kemampuan fungisida Curxanil 8/64 WP (campuran simoksanil dengan mankozeb 8/64 WP) di lapangan dalam mengendalikan Colletotrichum spp. Penelitian lapangan disusun berdasarkan Rancangan Acak Kelompok Lengkap dengan 5 perlakuan yaitu Curxanil dengan konsentrasi 0, 0,1, 0,2, 0,3, 0,4 %, dan mankozeb 0,2 % sebagai pembanding, dengan 4 ulangan. Percobaan di laboratorium bertujuan untuk menguji kemampuan fungisida Curxanil dengan mankozeb terhadap perkembangan koloni jamur patogen dan menguji ketahanan Colletotrichum spp. terhadap fungisida. Uji daya racun fungisida in vitro dirancang dengan Rancangan Acak Lengkap dengan 8 perlakuan yaitu 0, 50, 100, 200, 800, 1000, 1500, 2000 ppm dengan menggunakan Teknik Makanan Beracun. Uji ketahanan Colletotrichum spp. terhadap fungisida dilakukan dengan menumbuhkan patogen pada PDA dengan konsentrasi Curxanil yang dinaikkan secara bertahap. Hasil penelitian menunjukkan bahwa fungisida Curxanil mampu mengendalikan patogen pada konsentrasi 0,2 % di lapangan. Mankozeb 800 ppm dapat menghambat perkembangan koloni Colletotrichum spp., 98,8%. Campuran simoksanil dengan mankozeb pada 50 ppm sudah dapat menghambat 100%, sedangkan simoksanil tidak dapat menghambat perkembangan koloni Collletotricum spp. Sampai dengan 2000 ppm diameter koloni hanya terhambat 32,7%. Jamur Colletotrichum spp. menunjukkan kecenderungan ketahanan terhadap simoksanil setelah diperlakukan berulang kali dan masih dapat tumbuh 52,6%. Hal ini menunjukkan bahwa kemunculan strain Colletotrichum spp. tahan simoksanil dapat dihambat dengan fungisida campuran simoksanil dengan mankozeb.

Abstract

The aims of the research is to know the effect of phosphite acid and fosetyl-aluminium fungicides on Fusarium oxysporum f.sp. cubense (Foc) in vitro and the effect of these fungicides to fusarium wilt of banana. The experiments consist of in vitro and in planta tests. Fungicides concentrations used were 0; 500; 1,000; 2,000; and 4,000 ppm. Isolate tested was A13 isolate Foc on 4 months old Cavendish cultivar banana seedlings. The result showed that phosphite acid was better than fosetyl aluminium in reducing mycelium growth in vitro. Its also inhibited disease development in banana seedling. The phosphite acid and fosetyl-aluminium increased the resistance of banana Cavendish cultivar to fusarium wilt. Its because the two fungicides are working systemic fungicides.Penelitian ini bertujuan untuk mengetahui pengaruh fungisida asam fosfit dan aluminium-fosetil terhadap pertumbuhan jamur Fusarium oxysporum f.sp. cubense (Foc) in vitro dan pengaruh fungisida tersebut terhadap penyakit layu fusarium pada tanaman pisang. Penelitian ini terdiri dari 5 perlakuan kepekatan fungisida, yaitu 0 ppm (kontrol), 500 ppm, 1000 ppm, 2000 ppm, dan 4000 ppm. Isolat jamur yang digunakan yaitu Foc A13. Bahan tanaman adalah bibit pisang kultivar Cavendish asal kultur jaringan 4 bulan setelah aklimatisasi. Hasil penelitian menunjukkan bahwa fungisida asam fosfit (Agrifos) lebih efektif untuk menghambat pertumbuhan jamur Foc daripada fungisida aluminium-fosetil (Aliette) secara in vitro. Fungisida asam fosfit dan aluminium-fosetil menghambat perkembangan penyakit layu pada bibit pisang. Kedua fungisida tersebut juga meningkatkan ketahanan tanaman pisang terhadap penyakit layu fusarium. Hal ini disebabkan kedua jenis fungisida tersebut bekerja secara sistemik.
