Abstract

Detection and Identification of Endophyte Trichoderma Fungi Associated Cocoa PlantABSTRACT. The endophytic fungi are non pathogenic fungi and almost all of them associated with plant cells without any symptoms. Endophites fungi that associated with cacao plant from East Aceh has been isolated. Based on morphological and molecular identification was found two species of fungi Trichoderma spp which is fungal antagonist. Molecular identification have provided the species of Trichoderma virens and Trichoderma longibrachiatum. Trichoderma virens had goog poteny as biological control agains patogen.

Abstract

Spesies Nematoda Habitat Pada Pohon Pinus Mati Akibat Terserang Penyakit Layu Nematoda (Bursaphelenchus xylophilus).ABSTRAK. Spesies-spesies nematode habitat pada pohon pinus mati akibat terserang nematode (Bursaphelenchus xylophilus) telah diisolasi dan diidentifikasi. Lima belas spesies nematode telah terdeteksi, diantaranya (i) lima spesies nematode mycophagus: B. xylophilus, Bursaphilenchus n. sp., dan B. sinensis, Tylencida sp. 1, Tylencida sp. 2; (ii) Sembilan spesies nematode saprophagus: Diplogasterida sp. 1, Diplogasterida sp. 2, Diplogasterida sp. 3, Diplogasterida sp. 4, Monhisterida sp. 1, Monhisterida sp.2, Rhabditida sp. 1, Rhabditida sp. 2, Plectidae sp.; dan (iii) satu spesies nematode predator yaitu Mononchida sp. Dari setiap waktu pengamatan nematode B. xylophilus ditemukan merupakan spesies nematode yang paling dominan, dan diikuti oleh spesies Diplogasterida sp. 1.

Abstract

Abstrak: Fusarium oxysporum f.sp. lycopersici (Fol) adalah salah satu patogen tular tanah yang sangat berbahaya bagi tanaman tomat, hal itu dikarenakan patogen ini mampu bertahan dalam jangka waktu yang lama di dalam tanah. Salah  satu  alternatif  pengendalian  secara  biologi  yang  ramah  lingkungan  adalah dengan cara memanfaatkan cendawan antagonis sebagai agen biokontrol yaitu Trichoderma spp. penggunaan cendawan antagonis sebagai agen hayati harus dalam bentuk formula yang tepat dengan bahan yang mudah tersedia. Penelitian  ini   bertujuan  untuk  mengetahui  pengaruh  aplikasi  beberapa   bentuk formulasi  Trichoderma  spp  dalam  mengendalikan penyakit  layu  fusarium  pada  tanaman tomat. Penelitian ini menggunakan Rancangan Acak Lengkap pola non faktorial yang terdiri dari 4 perlakuan dengan menggunakan 5 ulangan, setiap ulangan terdiri dari 4 unit tanaman. Susunan perlakuan bentuk formulasi berbahan aktif Trichoderma spp yaitu F0 = Kontrol (tanpa perlakuan),F1 = Formulasi pelet daun katuk 3 g (+ 10 butir)/polibag, F2 = Formulasi padat jagung kering 3 g/polibag dan F3 = Formulasi cair produk komersil 100 ml/polibag. Hasil penelitian menunjukkan bahwa aplikasi beberapa bentuk formulasi  Trichoderma spp  mampu memberikan pengaruh yang nyata terhadap persentase layu tanaman dan tinggi tanaman serta persentase batang yang xylemnya terdiskolorasi. Application of Several Forms by Trichoderma spp Formulation in Controlling Fusarium Wilt Disease on Tomato PlantsAbstract. Fusarium oxysporum f.sp. lycopersici (Fol) is one of the soil pathogens that is very harmful for tomato plants, it is because these pathogens are able to survive for a long time in the soil. One of the alternative biological controls that are environmentally friendly is by utilizing the antagonist fungus as a biocontrol agent that is Trichoderma spp. the use of antagonistic fungi as biological agents should be in the form of the right formula with easily available materials. This study aims to determine the effect of application of some form of Trichoderma spp formulation in controlling fusarium wilt disease in tomato plants. This research uses Completely Randomized Design of non factorial pattern consisting of 4 treatments using 5 replications, each replication consisting of 4 plant units. the active formulation by several form formulation of Trichoderma spp is F0 = Control (without treatment), F1 = Leaf pelet formulation 3 g (+ 10 grain) / polybag, F2 = Dry corn solid formula 3 g / polybag and F3 = Commercial liquid product formulation 100 ml / polybag. The results showed that the application of some form of formulation Trichoderma spp able to give a real effect on the percentage of wilting plants and plant height as well as the percentage of stems that discoloration on xylem.
