Hamidson H, Suwandi S, Effendy TA. 2019. Development of some corn leaf diseases caused by mushrooms in  north Indralaya Sub-District Ogan Ilir District. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 528-534.  Palembang: Unsri Press. There have not been many reported of losses from corn disease. These diseases fluctuate from one place to another and from time to time, including leaf rust, Helminthosporium leaf blight, stem rot, cob rot by Diplodia, Ustilago, Aspergillus, etc., and viral diseases and fungi as well as. nematode root rot. This research was conducted to find types of diseases that attack the leaves of corn caused by fungi during generative phase. Information would include type and level of the disease. Plant samples were taken randomly for 50 mounds of mounds and observations were made with vulnerable time for seven days. The incidence of diseases found in the generative phase of corn plants were leaf rust (Puccinia polysora) and leaf blight (Bipolaris maydis Synonym Helminthosporium maydisY. Nisik. & C. Miyake). The percentage of incidence of the disease indicates that leaf rust disease in each village follows the include Tj. Pring, Tj. Senai, and Tj. Birds which were abouth: 83.15%; 80.42%; and 79.90%. Leaf disease in each village as follows: village Tj. Pring, Tj. Senai, and Tj. Bird: 52.02%; 86.79%; and 88.78%. The severity of the disease showed that leaf rust disease in each village as follows the village of Tj. Pring, Tj. Senai, and Tj. Birds: 50.98%; 47.22%; and 49.37%. Leaf disease in each village were as follows: village Tj. Pring, Tj. Senai, and Tj. Bird: 52.02%; 55.12%; and 55.30%.

Abstract

Soil microbes associated with rhizosphere are important for promoting plant growth and inducing resistance to diseases. The research was conducted to study the ability of Trichoderma spp. and Penicillium spp. isolated from rhizosphere in lowland swampy area for controlling damping-off disease caused by Rhizoctonia solani Khun. Trichoderma spp. and Penicillium spp. were cultured in bran, corn meal, and rice straw containing media and applied as inoculum to 2-weeks old seedlings. Application of two fungi isolates effectively induced resistance of chili plants to damping-off disease. Trichoderma spp. and Penicillium spp. were significantly reduced disease incidence by 61.5–100% to 46.2–100%, respectively and disease severity by 50–100% and 30–95.9%, respectively. This experiment showed the potential of Trichoderma spp. and Penicillium spp. as biocontrol agents to control damping-off disease on chili.

Abstract

Damping-off disease is commonly occurred in chili pepper field and always caused significant effect on chili production. This experiment was conducted to determine the ability of 14 isolates of Trichoderma isolated from lowland swampy area in South Sumatera against damping-off disease. The result showed that treatment of Trichoderma significantly inhibited damping-off disease caused by Rhizoctonia solani. Treatment of Trichoderma effectively reduced the percentage of pre-emergence damping-off, post-emergence damping-off, and disease severity by 51.8–100%, 80–100%, and 51.90–96.96%, respectively. The treatment was also capable to increase percentage of height and fresh weight of chili pepper seedling, i.e. 45.45–64.37% and 37.78–81.19%, respectively.

Abstract

Blast is the most important disease of rice and may cause significant losses in the reclaimed tidal swamp of South Sumatra. Water extracts of fermented composts prepared from straws of the vigorous rice plant were tested in pot experiment for their ability to control blast. Rice variety Ciherang was grown on mixture of field soil and 1% diseased rice straw (v/v) collected from a tidal swamp rice field. Incidence of panicle blast was reduced by 71−87% in response to application of compost extract. The compost extract did not affect seed germination and plant height, instead, it increased the yield. The rice straw from healthy and vigorous plants is potential as a source for blast disease control.

Abstract

Planting resistant varieties is the most effective control method and is recommended because it is safe for the environment. The problem to be raised in this study was the use of the same variety of maize in every growing season by farmers. The use of one of these varieties could cause a decrease in yield due to the resistance of the variety to certain pests and diseases.  This study aimed to provide information in the form of the use of sweet maize varieties resistant to leaf blight and potential to be planted in the swampy lowland of South Sumatra. The varieties used in this study were Bonanza F1, MB-01 Sweet and Love Sweet varieties. Based on the results of the study, as a whole the use of several varieties had a significant effect on the severity of leaf blight. The results of this study showed that there were differences in the response to resistance of each variety to leaf blight caused by the fungus Exserohilum turcicum. The observation of disease severity was carried out only in the vegetative phase. The highest disease severity was found in the Bonanza, Love Sweet, and MB-01 Sweet varieties at 16.90%, 9.99% and 7.07% respectively. The production data showed that there was no significant effect on the leaf blight. The MB-01 Sweet variety had the potential to be planted on swampy soil because it had resistance to blight and had a high production rate.

Abstract

Kacang panjang termasuk dalam Famili Fabaceae dan merupakan salah satu komoditi sayuran yang banyak diusahakan di daerah dataran rendah pada ketinggian 0-200 m dpl. Permintaan kacang panjang dipasaram terus meningkat, namun pasokan kacang panjang terbatas. Peningkatan produksi kacang panjang dapat dilakukan dengan cara perbaikan tingkat kerapatan tanam. Untuk meningkatkan hasil polong kacang panjang, bisa dilakukan beberapa upaya seperti dengan pengendalian kultur teknis. Bertujuan untuk mengetahui intensitas serangan hama dan penyakit dan perbedaan pengaruh pengendalian kultur teknis terhadap dua lahan tanaman kacang panjang. Penelitian dilaksanakan di lahan kacang panjang milik petani di Kecamatan Lempuing, Kabupaten Ogan Komering Ilir, Provinsi Sumatera Selatan Penelitian ini dilakukan dengan cara pengamatan langsung (Scan sampling) persentase serangan hama dan penyakit pada pertanaman kacang panjang.  Pengambilan sampel pada praktek lapangan ini diawali dengan menentukan jumlah guludan yang akan diamati. Penentuan skor gejala serangan hama maupun intensitas penyakit di lapangan ditentukan dengan mengamati gejala masing masing serangan hama dan juga penyakit pada tanaman kacang panjang.  Secara keseluruhan intensitas serangan hama dan penyakit pada lahan kacang panjang 1 milik Bapak Johari lebih banyak dibandingkan dengan lahan 2 milik Bapak Sutekno. Ada beberapa faktor yang mungkin mempengaruhi hal tersebut diantaranya tanaman rotasi yang digunakan, umur tanaman, penggunaan fungisida karena lahan 1 tidak menggunakan fungisida sama sekali sedangkan lahan 2 milik Bapak Sutekno mengaplikasikan fungisida pada tanaman kacang panjang miliknya. Kata kunci : tanaman kacang panjang, hama dan penyakit.

Abstract

Hamidson H, Suwandi S, Nurhayati N. 2020.  Epidemiology  of  leaves caused by fungi in corn plants in Indralaya Utara Ogan Ilir district. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aims to observe the development of disease in maize plants caused by fungi related to the epidemiology of leaves diseases caused by fungi in corn plants in Indralaya Utara District, Ogan Ilir Regency. The low production of maize is caused by the attack of plant-disturbing organisms from both pests and diseases. The survey results showed that two maize diseases were leaf blight and leaf rust. Leaf blight can reduce production by up to 50%. Leaf blight (Helminthosporium sp; Bipolaris sp; Exserohilum sp) and leaf rust disease (Puccinia sp). The highest incidence percentage was found in plants aged 60 DAS at 16.64%. The results of the seed health tests of the six types of corn seeds observed were Annom and Sukanegara seeds growing faster, Annom seeds growing faster on the surface of the seeds followed by Bisma, Lamuru, and Srikandi Kuning seeds. Annom seeds mostly carried seed fungi that grew on the seed surface followed by Bonanza seeds. Types of fungi carried by the seeds, namely Aspergillus sp; Penicellium sp; Trichoderma sp; Diplodia sp; and Bipolaris sp.
