Abstract

Fusarium wilt caused by Fusarium oxysporum .F. oxysporum including soil-borne diseases because it can survive in the soil in the form of klamidiospora,.  This fungus is relatively difficult to separate the soil. One technique is to use a control that disease-resistant varieties.  Some tomato varieties are known to have different resistance to fusarium wilt.  Some of these varieties are expected to break the life cycle of disease in the field.  The use of antagonistic fungi Trichoderma sp. can be hiperparasit on several species of fungi that cause plant diseases, growing very fast, and not become a disease of higher plants.  Trichoderma sp. naturally a parasite that many types of fungi attack the plant destroyer (broad spectrum control) and is a fungus that is involved in the natural competition among fungi.

Abstract

Research on the effect of Trichoderma sp. In tomato plants on the factors of production is a study carried out for 4 months starting from June to October 2017. The research was carried out at the Green House of the Faculty of Agriculture, Mulawarman University, Samarinda.This research was conducted using a completely randomized design (CRD) with each treatment repeated 3 times. The treatment is Po: Without Trichoderma sp. / Control treatment; P1: 25 g culture of Trichoderma sp. per polybag; P2: 30 g of mushroom culture Trichoderma sp. per polybag; P3: 35 g of mushroom culture Trichoderma sp. Per polybag; and P4: 40 g culture of Trichoderma sp. per polybag As the second factor, tomato varieties include V1: Lentana; V2: Permata and V3: Ratna. The data observed included the number of planting fruit (calculated from the first harvest to the last harvest for each crop); Average diameter of planting fruit and. The average weight of fresh fruit plantations.The results showed that the dose of 40g Trichoderma sp. most effective in controlling F. oxysporum wilt disease on tomato plants, which can increase tomato crop production by 293.48 g. Variety treatment was not significantly different from all treatments. So that there is no interaction between Trichoderma sp. and tomato varieties.

Abstract

Penelitian dilakukan untuk menentukan: cendawan endofit yang terdapat pada tanaman padi (Oryza sativa); persentase daya hambat cendawan endofit terhadap cendawan Pyricularia oryzae Cav.; dan mekanisme antagonis antara masing-masing cendawan endofit terhadap cendawan Pyricularia oryzae Cav.. Penelitian dilakukan di laboratorium terpadu Fakultas Pertanian Universitas Mulawarman, dan sampel tanaman yang terinfeksi serta tanaman sehat dikumpulkan dari Kelurahan Sungai Kapih, Kecamatan Sambutan, Kota Samarinda. Hasil penelitian disusun dalam Rancangan Acak Lengkap (RAL), yang terdiri dari empat sampel dan setiap sampel diulang sebanyak sepuluh kali. Hasil penelitian menunjukkan bahwa cendawan endofit yang terisolasi dari tanaman padi (Oryza sativa) adalah Trichoderma sp., Rhizopus sp., Gliocladium sp. dan Penicillium sp. Kompetisiterbukti secara in vitro sebagai mekanisme antagonis Rhizopus sp., sedangkan antibiosis terbukti secara in vitro sebagai mekanisme Penicillium sp.. Trichoderma sp dan Gliocladium sp terbukti memiliki dua mekanisme antagonis yaitu kompetisi dan parasitisme. Kemampuan cendawan endofit sebagai agen biologis untuk bersaing dengan cendawan P. oryzae itu menghasikan perbedaan daya antagonisme, tingkat tertinggi penghambatan terjadi padaP.oryzae vs Gliocladium sp. (78,96%).

Abstract

Penelitian ini dilakukan untuk mengetahui status keragaman nematoda pada lahan reklamasi pasca tambang batubara dan hutan sekunder (pembanding). Penelitian ini dilakukan di Fakultas Pertanian Universitas Mulawarman selama 4(empat) bulan. Pengambilan sampel tanah dilaksanakan di Desa Bangun Rejo Kecamatan Tenggarong Seberang, Kalimantan Timur. Dilanjutkan dengan ekstraksi nematoda menggunakan metode Baermann yang dimodifikasi, dan identifikasi nematoda yang didapatkan sampai tingkat genus berdasarkan ciri morfologinya. Pengamatan nematoda dilakukan di laboratorium Ilmu Hama Penyakit Tumbuhan Fakultas Pertanian Universitas Mulawarman Samarinda. Hasil penelitian menunjukkan bahwa ditemukan 14 genera nematoda, terdiri dari 6 genera nematoda non-paasit dan 8 genera parasit tumbuhan. Genus nematoda yang dominan secara berturut-turut adalah sebagai berikut: Apelenchus, Cephalobus, Dorylaimus, Pratylenchus, dan Rhabditis. Kepadatan populasi nematoda berkisar 30-206 individu 100 gram-1 tanah. Keanekaragaman nematoda pada lahan reklamasi tergolong sedang dengan indeks Shannon-Wienner berkisar 1,22-3,09, sedangkan pada lahan pembanding (hutan sekunder) tergolong tinggi dengan indeks Shannon-Wienner berkisar 3,06 – 3,49. Kata kunci : Lahan Reklamasi Pasca Tambang Batu bara, Keragaman Nematoda, Indikator Biologi.

Abstract

Penyakit blas merupakan salah satu penyakit utama pada tanaman padi yang mampu menimbulkan kerugian besar bagi para petani sehingga petani mengendalikan penyakit ini dengan menggunakan bahan kimia yang merusak lingkungan dan menimbulkan dampak negatif lain. Melihat pentingnya pengendalian penyakit ini maka dibutuhkan alternatif pengendalian dengan menggunakan agens pengendali hayati. Percobaan dilakukan di Kelurahan Sungai Kapih, Kecamatan Sambutan, Kota Samarinda, dari Desember 2020 hingga April 2021. Hasil percobaan disusun dalam Rancangan Acak Kelompok (RAK) faktorial, yang terdiri dari tiga varietas, dengan lima perlakuan dan diulang sebanyak lima kali. Hasil penelitian menunjukkan bahwa varietas Ciherang merupakan varietas yang paling rentan dibandingkan varietas Kambang dan Pandan Ungu. Cendawan endofit yang diaplikasikan terhadap tanaman memberikan pengaruh yang baik untuk pengendalian penyakit Blas dan juga meningkatkan ketahanan tanaman, dalam hal ini cendawan yang memberikan efektivitas terbaik yaitu cendawan Trichoderma sp. yang mampu menekan intensitas serangan penyakit blas lebih dari 85% sehingga dapat digunakan sebagai alternatif pengendalian yang ramah lingkungan.

Abstract

Endemic leaf rust disease always occurs in almost all maize plantations in Indonesia. Furthermore, the development of this disease differs concurrently and is greatly influenced by the ecological conditions of maize cultivation. Therefore, this study fills the epidemiological gap of diseases that has not been conducted against the epidemiology of maize rust. This identifies the causes of leaf rust that attacked the maize plants in two locations, namely Bayur and Muang Dalam, Lempake, Samarinda, Indonesia. This study also analyzed the relationship or model between ecological factors of temperature, humidity, and soil fertility on the intensity of leaf rust and the infection rate of maize leaf rust. Measurement of disease intensity, the rate at which it developed, soil fertility and temperature and humidity of the area are conducted in this study. Meanwhile, soil fertility also influenced disease progression and the nutrient-poor soils in two sites cause leaf rust disease to develop well. The identification results showed that the cause of maize leaf rust was Puccinia sorghi Schw. Therefore, the temperature accompanied by the increased humidity is directly proportional to the development of the leaf rust.

Abstract

The study entitled Persistence of the virus that causes mosaic disease in chili seeds originating from the production of chili plants that are attacked by a virus that is treated by soaking at some temperature aims to see the persistence or presence of the virus that causes the mosaic. The persistence of the virus is done by observing the chilli seedlings that are 8 weeks after planting. The research was carried out at the Plant Pest and Disease Laboratory, Faculty of Agriculture, Mulawarman University, Samarinda. The study was conducted using the observation method that is directly observing the treatment carried out. This study used 5 treatments and each of 4 replications, consisting of: C1 = treatment of warm water with a temperature of 40 ° C for 10 minutes, C2 = treatment of warm water with a temperature of 45 ° C for 10 minutes, C3 = treatment of warm water with a temperature 50 ° C for 10 minutes, C4 = treatment of warm water with a temperature of 55 ° C for 10 minutes, Cs = treatment of warm water with a temperature of 60 ° C for 10 minutes. The results showed that soaking warm water had an influence on the persistence of viruses carried in the seeds to the development of mosaic disease in chilies. Temperatures of 50 ° C and above have been able to prevent mosaics disease at chillie plant.
