Abstract

Resistance of Several Local Rice Varieties to Isolate Tungro Virus from Muara Tungro disease is one of the important diseases in rice because it causes stunted plants and may induce significant yield losses. Planting resistant varieties is a recommended control strategy to overcome tungro disease. The research was conducted to find sources of genetic resistance from local rice varieties that can be used in breeding of tungro disease resistant varieties. The experiment was arranged in a descriptive research design with observational techniques. Observations were made on 16 local rice varieties with each variety consisting of 30 sample plants so that the number of plants used was 480 plants. The isolate of tungro virus collected from rice field in Muara, Bogor was inoculated to the test plants through the insect vector, green leafhopper (Nepothettix virescens). The results showed that the resistance of local varieties varied based on the value of disease index, disease incidence and plant height reduction. ‘TN1’ was the check susceptible variety against tungro virus, while the local rice varieties were differentiated into resistant (‘Utri Merah’), moderate (‘Karau’, ‘Bekongan’, ‘Bujang Bernai’, ‘Srogel Abang’, ‘Pulut Garu’, ‘Randu Range’, ‘Siredep’, ‘Katimpung’, ‘Pulut Sawijan’, ‘Dube’), moderate tend to be susceptible (‘Blumbungan’, ‘Tjere bandung’, ‘Sempor’) and susceptible (‘Rumbai’). All varieties can be infected (disease incidence 27 – 76%), but disease severity varies greatly (3–7). The more severe the disease, the higher the plant height reduction. ‘Srogel Abang’ is a variety that is useful for breeding rice varieties resistant to tungro disease because it showed moderate response with a low percentage of plant height reduction (36%) so that plant productivity can still be maintained.

Abstract

ABSTRACT Plant disease control using biological agents such as Trichoderma spp., and groups of bacteria that are members of Plant Growth Promoting Rhizobacteria or PGPR is an organic farming method, which only uses ingredients that come from the surrounding environment. The purpose of implementing this PKM is to introduce farmers to an alternative control method that is safer for the environment, cheaper because it comes from their own residential environment so that it does not cost more but is effective in controlling plant pests or OPT. Another goal is that farmers can reduce the frequency of using non-organic pesticides in their daily cultivation systems. The delivery method is carried out in the mentoring method through the presentation of recipes, procedures and manufacturing techniques carried out at the Kwau Village Hall; while the training is carried out in farmers' gardens with the presentation of the parts of the sprayer used, how to mix organic pesticides, the dosage size used and the best spraying time. This training and mentoring received a warm welcome from the farming community which was marked by not only being attended by the farming community in Kwau but also by farmers from other villages around Kwau village such as Maybrij and Soubrij. Another thing that shows high enthusiasm is the curiosity about the material during the discussion and training in the farmer's garden. We hope that the material presented can add insight into the agrotourism cultivation system.  Keywords: Bamboo, Plant Pest Organisms, Plant Growth Promoting Rhizobacteria, Kwau, Trichoderma spp   ABSTRAK  Pengendalian penyakit tanaman dengan menggunakan agensia hayati seperti Trichoderma spp., dan kelompok bakteri yang tergabung pada Plant Growth Promoting Rhizobacteria atau PGPR merupakan cara bertani secara organik, yang hanya menggunakan bahan-bahan pembuat yang berasal dari alam sekitar. Tujuan pelaksanaan PKM ini adalah memperkenalkan kepada petani suatu metode pengendalian alternatif yang lebih aman terhadap lingkungan, murah karena berasal dari lingkungan tempat tinggal sendiri sehingga tidak mengeluarkan biaya lebih tetapi efektif dalam mengendalikan Organisme pengganggu tumbuhan atau OPT. Tujuan lainnya lagi adalah petani dapat mengurangi frekuensi penggunaan pestisida non-organik dalam sistem budidaya sehari-hari. Metode penyampaian dilaksanakan dalam metode pendampingan melalui pemaparan resep, prosedur dan teknik pembuatan yang dilaksanakan di Balai Kampung Kwau; sedangkan pelatihan dilaksanakan di kebun milik petani dengan pemaparan bagian-bagian alat sprayer yang digunakan, cara pencampuran pestisida organik, ukuran dosis yang digunakan dan waktu penyemprotan terbaik. Pelatihan dan pendampingan ini mendapat sambutan yang meriah dari masyarakat petani yang ditandai oleh bukan hanya dihadiri oleh masyarakat petani di Kwau juga dihadiri oleh petani yang berasal dari kampung lainnya di sekitar kampung Kwau seperti Maybrij dan Soubrij. Hal lainnya yang menunjukkan animo yang tinggi adalah keingintahuan terhadap materi pada saat diskusi dan pelatihan di kebun petani dilakukan. Harapan kami materi yang disampaikan dapat menambah wawasan dalam sistem budidaya agrowisata.  Kata kunci:  Bambu, Organisme Pengganggu Tumbuhan, Plant Growth Promoting Rhizobacteria, Kwau, Trichoderma spp
