Abstract

Jagung adalah komoditas unggulan Kabupaten Lampung Timur. Invasi hama Spodoptera frugiperda menjadi masalah serius dalam budidaya jagung. Sejak awal masuknya hama S. frugiperda pengendalian yang dilakukan oleh petani di Kecamatan Batanghari Nuban adalah dengan mengunakan insektisida berbahan aktif emamectin benzoat. Namun penggunaan bahan aktif yang sama dalam waktu yang cukup lama dapat mempercepat terjadinya resistensi. Berdasarkan laporan dari Penyuluh Pertanian Lapangan (PPL), beberapa desa di Kecamatan Batanghari Nuban telah mengalami resistensi emamectin benzoat. Berdasarkan hal tersebut dirasa sangat perlu dilakukan penyuluhan terkait pengendalian S. frugiperda yang efektif ramah lingkungan. Tujuan dari kegiatan ini adalah untuk memberikan solusi dalam pengendalian hama invasif S. frugiperda yang telah mengalami resistensi terhadap bahan aktif emamectin benzoate dengan menggunakan perangkap berferomon. Perangkap berferomon ini dapat mengendalikan populasi S. frugiperda dengan cara yang ramah lingkungan sehingga mengurangi kerusakan pada tanaman jagung dan juga mengurangi dampak negatif penggunaan insektisida. Dengan demikian dapat mengurangi kerugian secara ekonomi dan mendukung sistem pertanian yang berkelanjutan. Hasil dari kegiatan ini petani dapat menggunakan feromon untuk memerangkap imago jantan S. frugiperda, sehingga dapat menurunkan populasi hama pada pertanaman jagung. Dengan menggunakan petangkap berferomon, petani dapat mengurangi biaya pengendalian dengan insektisida. Selain itu, dampak negatif dari insektisida juga dapat dikurangi.

Abstract

Root and basal stem rot is one of important diseases in sugarcane plantations in South Sumatra and Lampung. This disease is caused by Xylaria sp. The study is aimed to determine the fungicides sensitivity of Xylaria sp. which is associated with root and stem rot disease of sugarcane. The Xylaria sp. was isolated from the stroma and diseased sugarcane stems obtained from PT Gunung Madu Plantations (GMP). The fungicides used were plant base fungicides (puyangan and jamuan) and synthetic fungicides (carbendazim, mancozeb, and chlorothalonil). The Xylaria sp. sensitivity test was carried out by the poison food technique. The doses used are; puyangan and jamuan (10 g/100 mL), carbendazim (2 g/L), mancozeb (3 g/L), and chlorothalonil (1 g/L). The rate of sensitivity change of Xylaria sp. on fungicides was test by subculturing the Xylaria sp. in media containing fungicides at a dose of 9 g/100mL (puyangan and jamuan), 0.1 g/L (carbendazim), and 0.5 g/L (mankozeb) three times. The results showed that the Xylaria sp. which is associated with root and basal stem rot disease of sugarcane is still very sensitive to fungicides puyangan, jamuan, carbendazim, and mancozeb at recommended doses, but is very resistant to chlorothalonil on 2x the recommended dose. The results of the rate of change in sensitivity of Xylaria sp. to fungicides showed that isolate A tended to change more quickly compared to isolate B and isolate C.

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).

Abstract

Downy mildew, caused by Peronosclerospora spp., is one of the major problems in maize cultivation. Several studies have reported the development of resistance in Peronosclerospora spp. to metalaxyl, which had previously been an effective control method for the disease. Other research suggests that the efficacy of phosphonic acid in controlling downy mildew in maize is inconsistent. The objective of this study was to evaluate the efficacy of seed treatment with phosphonic acid in controlling downy mildew in Bisi 18 maize. The treatments were arranged in a randomized block design with six replications. The observed variables included the incidence and severity of the disease, the area under the disease progress curve (AUDPC), maize yield, and the content of tannin and hydroquinone compounds in maize leaves. The results showed that both phosphonic acid applied by spraying and seed treatment significantly reduced the incidence and severity of downy mildew (P < 0.05). However, the concentrations of phosphonic acid used in seed treatment had no significant effect on the disease during 1–7 weeks after inoculation. Furthermore, all phosphonic acid treatments tended to increase the content of tannin and hydroquinone compounds in maize leaves, which should be confirm quantitatively.

Abstract

Begomoviruses are a group of plant viruses belonging to the Geminiviridae family, persistently transmitted by the whitefly Bemisia tabaci, and pose a serious threat to horticultural crops in Lampung Province, Indonesia. These viruses infection symptoms such as mosaic, chlorosis, leaf curling, and stunted growth, with yield losses reaching up to 90%. The spread is exacerbated by intensive cultivation practices, the use of uncertified seeds, and tropical climates that favor high vector populations. This study explores the biological characteristics of Begomoviruses, their transmission mechanisms via vectors, and their high genetic variability due to frequent mutation and recombination. Several begomovirus species have been identified infecting key horticultural crops in Lampung, including Ageratum yellow vein virus (AYVV), Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV), and Pepper yellow leaf curl Indonesia virus (PepYLCIV). In addition to vector transmission, some begomovirus species are also known to be seed-transmitted, expanding their epidemic potential. Integrated management strategies discussed in this article include the use of resistant varieties, biological and agronomic control of vectors, and the development of innovative approaches such as mild strain cross-protection. This review emphasizes the need for continuous monitoring and science-based sustainable strategies to mitigate the impact of Begomoviruses on food security and horticultural productivity in tropical regions such as Lampung.

Abstract

This study aims to determine the pathogen characteristics of papaya stem cancer and identify alternative host plants other than papaya. The research was conducted from October 2020 to May 2021 in the Laboratory of Agricultural Biotechnology and the Laboratory of Plant Diseases, Faculty of Agriculture, University of Lampung. Four bacterial isolates suspected to be the cause of papaya stem cancer in Limau (Tang 2(1), Tang 2(2), Ptl 1(2), Ptl 2(2)) were used in this study. Bacterial characterization was determined based on the results of biochemical tests. The results showed that the bacterial isolates were gram-negative, fermentative, lecithinase-negative, soft rot-negative, and hypersensitivity-negative, and did not produce fluorescence on King's B media. All isolates were positive for the arginine dihydrolase test, except for Tang 2(2) and Ptl 1(2). All isolates showed a negative reaction in the casein test, except for Tang 2(2). All isolates were able to grow at 39 °C or 40 °C. All bacterial isolates were able to utilize mannitol, L-tartrate, and mannitol, but not ascorbic acid. The results of the host range test showed that the bacteria were able to infect and cause symptoms in eggplant, chickpeas, luffa, and long beans. A pathogenicity test was conducted on 2-month-old papaya seedlings (cv. Calina). The results showed that all four bacterial isolates from Limau caused stem cancer symptoms in the papaya seedlings.

Abstract

Cayenne pepper (Capsicum frutescens) is a horticultural commodity with high economic value and increasing demand. Anthracnose disease is a major limiting factor in cayenne pepper cultivation, with yield losses reaching up to 60%. Control of anthracnose is generally achieved through fungicide application. However, the extensive use of fungicides has led to the emergence of resistant strains and environmental pollution. Various plants have been reported to contain antifungal bioactive compounds. This study aims to determine the potential of mangrove extract to control Colletotrichum sp., the cause of anthracnose disease in cayenne pepper. The research was conducted at the Plant Disease Science Laboratory, Faculty of Agriculture, University of Lampung. The tested mangrove species were some part of Avicennia marina. In vitro testing was carried out using a poison food method and arranged in a completely randomized design with 5 replications. The treatments in the in vitro test included: no mangrove extract, extracts from the fruit, root, leaves, stem, and bark of A. marina. In vivo testing was conducted using a completely randomized design with 3 replications. The treatments consisted of: no mangrove extract, extracts from the root, leaves, stem, and bark of A. marina. The results indicate that extracts from various parts of A. marina inhibited the growth of Colletotrichum sp. colonies, except for extracts from A. marina root and leaf. However, all extracts from A. marina did not affect the sporulation of Colletotrichum sp., the cause of anthracnose in cayenne pepper. Furthermore, extracts from different parts of A. marina did not impede the occurrence or severity of anthracnose on cayenne peppers
