Abstract

Efficacy of selected Trichoderma isolate and organic matter to control foot rot of black pepper in the field. The objective of this experiment was to determine the efficacy of selected Trichoderma isolatand organic matter to control the disease. Dual culture method was used to select a Trichoderma isolate. The experiment to evaluate the efficacy of selected isolate consisted of control (no application of T. harzianum or organic matter), T. harzianum and rice straw, and T. harzianum and coffee husk. As starter, T. harzianum was grown in broken rice. Two liters of organic matter was infested with suspension of 10 g starter in 100 ml steril water and incubated for 2 weeks. The mixture was applied around the base of black pepper stem. The results showed that all plants treated with T. harzianum and organic matter did not show disease symptom. Ten percent of the control plants showed symptoms. However, statistical analysis showed that the occurrence of the disease was not significantly different between treatments. Applications ofT. harzianum and rice straw increased the density of Trichoderma for 1 and 2 months after application. T. harzianum and coffee husk increased the density of the fungus 1 month after application.

Abstract

Effectiveness of the application of organic matter and Trichoderma viride from suppresive soil to control fusarium wilt on banana plant. Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense is one of the problems in banana production. This research was aimed to evaluate the effect of  Trichoderma viride isolated from suppresive soil and organic matter on controlling fusarium wilt on banana plant. The efficcacy trial consisted of 12 treatments and four replications within each treatment. Each experimental unit consisted of 10 plants. Organic matters used were rice straw, cassava peel, and compost. Treatments were arranged in a randomized complete block design. Data obtained were analyzed by analysis of variance followed by orthogonal analysis (P?0.05). Application of T. viride suppressed disease incident up to 65%. The highest disease incident occurred in plants treated without T. viride and organic matter and in plants treated with organic matter only (78.33%). Disease incidence in plants treated with T.viride was lower than those treated with the combination of T. viride and organic matter. Different application times (in nursery or soil medium) did not significantly affect fusarium wilt incidence. The type of organic matter did not significantly affect the incidence and severity of fusarium wilt.

Abstract

Preliminary test on the effect of water extract from plants on rust incidence on coffee leaf disks at the latroratory. The objective of this study was to determine the influence of several water extract from plants on rust incidence on coffee leaf disk a laboratory condition. The study was done from March to June 2003. Treatments were arranged in a randomized complete block design with four replications, One experimental unit consisted of eight leaf disks with 2 cm in diameter. To prepare water extract, 1 00 g of plant or its part was homogenized with 100 ml sterilized distilled water.  After being passed through four layers of sterilized cheesecloth, the mixture was defined as the aliquot. Ten percent of the aliquot was sparyed on leaf disks before inoculation. As inoculum, uredospores developed on leaves under field condition were taken with sterilized scalpel and placed in sterilized distilled water and counted with hemacyometer to get suspension (4x105 uredospores per ml) spores per ml). Data on disease incidence were analyzed with ANOVA and Duncan test. The results showed that disease incidence was significantly reduced by water extract processed from the leaves of Piper betle, Azadirachta indica, and Eugeni aromatica, the rhizomes of Zingiber afficinale and Curcumq longa, stem of Cymbopogon citratus, Allium ascalonium, A.sativa, and copper fungicide. Disease was not significantly reduced in leaf disks sprayed with extract prepares from the leaves of Piper retrofractum, P. nigrum,  the rhizomes of Imperata cylindrica and Alpina galanga, A. cepa,Ageratum comysoides, and Elephantopus scaber.

Abstract

Trichoderma has the potential to suppress fungal pathogens and thus control plant diseases, including Phytophthora foot rot, which is the most devastating disease of black pepper in Lampung. Identification of a microorganism can not only rely on its morphological characteristics, but it is also necessary to identify it molecularly at the species level. This research was aimed at identifying the fungus Trichoderma sp. Margodadi isolates at the species level and to know the potential of Trichoderma sp. Margodadi isolates and their secondary metabolites to control P. capsici. This research was conducted from March to November 2021 at the Laboratory of Plant Disease, Department of Plant Protection, and the Laboratory of Agricultural Biotechnology, Faculty of Agriculture, University of Lampung. Identification of Trichoderma was done by morphological characteristics and molecular methods. The ability of Trichoderma to suppress P. capsici was tested by dual culture. The effect of secondary metabolites on the growth of P. capsici was determined in vitro at concentrations of 0% (control), 10%, 20%, 30%, and 40%. The experimental design used was a completely randomized design consisting of five treatments repeated five times. The data obtained from the test were analyzed using ANOVA, followed by the LSD test at 5%. The results of this study showed that Trichoderma sp. Margodadi isolate had a close relationship with Trichoderma asperellum and had the ability as an antagonist to inhibit the growth of P. capsici up to 47.23%, and the secondary metabolites produced could inhibit the growth of P. capsici up to 72.53% with the best concentration of 40%.

Abstract

Abstrak: Kecamatan Tanjung Bintang merupakan salah satu penyokong produksi jagung provinsi Lampung. Produksi jangung di Desa Rejo Mulyo, Kecamatan Tanjung Bintang belum mencapai produksi optimum. Hal ini karena berbagai permasalahan yang dihadapi oleh petani, diantaranya benih, pemupukan, serta permasalahan hama dan penyakit tanaman jagung. Upaya mengatasi masalah hama dan penyakit umumnya dilakukan dengan penyemprotan pestisida oleh petani. Beberapa pestisida sulit terurai, sehingga penggunaan pestisida dalam jangka waktu yang lama berdampak negatif terhadap lingkungan, pencemaran terhadap produk pertanian, serta resistensi hama dan patogen tanaman. Metode yang digunakan adalah pembimbingan melalui sosialisasi mengenai hama dan penyakit pada tanaman jagung, pemanfaatan agensia hayati untuk pengendalian hama dan penyakit jagung, dan pelatihan pembuatan dan perbanyakan massal agens hayati Trichoderma. Hasil kegiatan pengabdian kepada masyarakat yang telah dilaksanakan dapat disimpulkan: 1. Kegiatan pengabdian kepada masyarakat diikuti oleh anggota dan pengurus Gapoktan Jaya Makmur, Desa Rejo Mulyo, kecamatan Tanjung Bintang, Lampung Selatan, Penyuluh Pertanian Desa Rejo Mulyo, dan para petani; 2. Peserta sangat antusias mengikuti kegiatan yang ditunjukan oleh keaktfannya dalam menyimak dan merespon penyampaian materi serta aktif bertanya dan memberi tanggapan terhadap setiap permasalahan yang dibahas, 3. Adanya peningkatan penguasaan pengetahuan tentang pengenalan hama dan penyakit pada tanaman jagung yang signifikan yang ditunjukkan oleh hasil evalusai setelah diberi penyuluhan lebih yaitu mayoritas peserta memiliki pengetahuan yang baik hingga sangat baik (85,9%) dan tidak ada peserta yang memiliki nilai dengan kriteria kurang.

Abstract

Abstrak: Sebagian besar anggota kelompok tani Setia Bakti di Pekon Tritunggal Mulya Pringsewu menanam cabai. Gangguan hama yaitu ulat grayak dan ulat buah serta penyakit tanaman merupakan masalah serius yang dihadapi petani dalam budidaya cabai. Aplikasi pestisida kimiawi tidak menunjukkan hasil yang memuaskan. Kegagalan dalam mengatasi masalah hama dan penyakit tanaman cabai ini salah satunya disebabkan oleh pengetahuan petani tentang prinsip-prinsip pengelolaan hama dan penyakit pada tanaman cabai masih kurang. Berdasarkan alasan ini maka perlu diadakan pengabdian kepada masyarakat (PKM) tentang pengelolaan hama dan penyakit pada pertanaman cabai bagi petani anggota kelompok tani Setia Bakti di pekon Tritunggal Mulya Pringsewu. Tujuan kegiatan PKM ini adalah untuk meningkatkan penngetahuan petani tentang jenis-jenis, bioekologi dan pengelolaan hama dan penyakit penting tanaman cabai. Kegiatan PKM dilaksakan di pekon Tritunggal Mulya kecamatan Adiluwih, kabupaten Pringsewu bulan Mei – Oktober 2023. Mitra yang terlibat dalam PKM ini adalah anggota kelompok tani Setia Bakti. Metode PKM yang diterapkan adalah penyuluhan di dalam ruangan. Hasil kegiatan sebagai berikut: 1) Antusiasme peserta selama kegiatan berlangsung tinggi yang ditunjukkan oleh kehadiran peserta melebihi jumlah yang diundang, keaktifan peserta menyimak dan berpartisiapasi aktif dalam diskusi, 2) Terjadi peningkatan pengetahuan peserta yang signifikan setalah megikuti kegiatan PKM yang ditunjukkan oleh petani dengan nilai kategori sangat baik (>70) mencapai 91%,. Dari hasil PKM ini dapat disarankan untuk melakukan PKM lanjutan dengan topik pembuatan kompos dari limbah pertanian dan kotoran ternak sapi yang dihasilkan kelompok tani Setia Bakti untuk memupuk pertanaman cabai dan tanaman lain.

Abstract

Downy mildew is one of the main diseases in maize which can reduce production. The objectives of this study were to determine the effect of phosphorous acid, dimetomorph, and metalaxyl fungicides on the germination and tube length of Peronosclerospora maydis conidia and the effect of phosphorous acid, dimetomorph, and metalaxyl fungicide treatment on conidia on the intensity of downy mildew in plants inoculated with these conidia. This study consisted of two tests, i.e., in vitro tests (effect on conidia germination and tube length) and in vivo tests (effect on downy mildew intensity). In both tests, a randomized block design (RBD) was used with four treatments and six replications. The results showed that phosphorous acid and dimethomorph fungicides inhibitted germination and reduced the length of conidia sprout tubes and suppressed downy mildew intensity. Meanwhile, metalaxyl fungicide was not effective in suppressing germination and conidia tube length and the intensity of downy mildew.

Abstract

The coffee industry is still impacted by the leaf rust disease caused by Hemileia vastatrix B. et Br. Coffee plants are damaged and money might be lost as a result. The purpose of this study was to observe the effects of copper oxide, betel leaf extract, and the fungus Lecanicillium lecanii on lab-grown coffee leaf discs in terms of disease control, namely coffee leaf rust. To measure efficacy, coffee leaf discs were used. In a completely randomized design (CRD), four treatments were used with five replicates for this experiment. The treatments that were used were L lecanii, betel leaf extract, copper oxide, and a control group. Observed parameters on coffee leaf discs were incubation length, sickness incidence, and disease severity. For data assessment, we utilized Barlett's test, and for data additiveness, we used Tukey's test. After analyzing the data using ANOVA, Duncan's Multiple Range Test was conducted at the 5% level. Results showed that L lecanii, copper oxide, and betel leaf extract may all extend the incubation period. In the betel leaf extract group, signs of coffee leaf rust disease appeared 14 days after inoculation (DAI), in the copper oxide group, 21 days after inoculation (DAI), and in the control group, 5 days after inoculation (DAI). In addition, L lecanii, betel leaf extract, and copper oxide significantly reduced the frequency of sickness and the severity of rust disease on coffee leaf discs in the lab 1-4 weeks after inoculation (WAI).
