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

Bleeding disease in tangerine plants is caused by the fungus Botryodiplodia theobromae. This study aimed to determine the effect of Cyperus rotundus L. extract on the growth of B. theobromae mycelia and spores in vitro, and to determine the best concentration of C. rotundus extract in inhibiting the growth of the fungus. The study was conducted using a Completely Randomized Design (CRD) consisting of 7 treatments, namely C. rotundus extract concentrations of 0.0% (control), 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%, as well as a fungicide treatment containing the active ingredient carbendazim 0.1%. The observed variable was fungal growth measured by colony diameter. The results showed that the treatment of sedge rhizome extract was able to suppress the development of B. theobromae fungal colonies. This nutmeg rhizome extract has the potential to be developed as a botanical pesticide to control B. theobromae fungus, and a concentration of 0.5% nutmeg rhizome extract has the highest inhibitory power against the growth of B. theobromae fungus, namely 56%.

Abstract

Rendahnya produksi bawang merah di Indonesia disebabkan salah satunya oleh penyakit moler (Fusarium oxysporum). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati dan pupuk kandang terhadap intensitas penyakit moler, mengetahui pengaruh pemberian pupuk hayati dan pupuk kandang terhadap produksi bawang merah, dan mengetahui interaksi dari pupuk hayati dan pupuk kandang terhadap intensitas penyakit moler dan produksi bawang merah. Penelitian ini dilaksanakan di Laboratorium Ilmu Penyakit Tanaman, Fakultas Pertanian dan Laboratorium Lapang Terpadu Fakultas Pertanian Universitas Lampung pada November 2019 sampai dengan Februari 2020. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 3 ulangan. Delapan perlakuan tersebut adalah tanpa pupuk hayati dan tanpa pupuk kandang (P0K0), tanpa pupuk hayati+pupuk kandang ayam (P0K1), tanpa pupuk hayati+pupuk kandang kambing (P0K2), tanpa pupuk hayati+pupuk kandang sapi(P0K3), pupuk hayati 10 ml/l+tanpa pupuk kandang (P1K0), pupuk hayati 10 ml/l+pupuk kandang ayam (P1K1), pupuk hayati 10 ml/l+pupuk kandang kambing (P1K2), dan pupuk hayati 10 ml/l+pupuk kandang sapi (P1K3). Hasil penelitian menunjukkan bahwa pemberian pupuk hayati dan pupuk kandang mampu menekan intensitas penyakit moler dengan P1K2 36% pada 4 MST dan 5,3% pada 6 MST pada keterjadian penyakit sedangkan pada keparahan penyakit P1K2 7,2% pada 4 MST dan 1,1% pada 6 MST. Pemberian pupuk hayati dan pupuk kandang menunjukkan bahwa tidak berbeda nyata pada variabel bobot tanaman umbi basah dan kering angin. Hal tersebut diduga karena tanaman tidak maksimal menyerap unsur hara dan tidak ada pemberian pupuk kimia.

Abstract

Spodoptera frugiperda (FAW), or fall armyworm, is a major invasive pest that attacks corn crops in various tropical and subtropical regions. In recent decades, the global spread of FAW has been accelerated by international trade and climate change. In Indonesia, the presence of this pest was first reported in 2019 in West Sumatra, with attacks spreading to various other areas. The FAW life cycle includes four stages (eggs, larvae, pupae, and imago) with significant levels of plant damage, especially in the larval stage.Various con- trol strategies have been implemented, including integrated pest management (IPM) approaches, such as the use of biological agents (Beauveria bassiana and Metarhizium anisopliae), push-pull techniques, and crop rotation. In addition, the development of pest-resistant corn varieties is an important alternative. Recent re- search has identified two genetic lines of FAW, namely corn and rice lines, which show differences in host preference and resistance to insecticides.This study highlights the need for further development of ecologi- cally based strategies, including exploration of local parasitoids and effective bioinsecticide formulations. In addition, genetic and microbiota analyses offer new potential in understanding FAW population dynamics and its control. These results are expected to be the basis for sustainable pest management in Indonesia and other regions.

Abstract

Pengembalian limbah dari perkebunan berupa serasah dan limbah pabrik berupa blotong tebu ke lahan menjadi salah satu upaya pemanfaatan limbah sebagai sumber bahan organik. Pengembalian limbah ke lahan sebagai sumber bahan organik membutuhkan waktu yang cukup lama sehingga perlu dilakukan pengomposan. Pengomposan serasah dan blotong tebu membutuhkan waktu yang lama karena kandungan selulosa, hemiselulosa, dan lignin dalam serasah tebu begitu tinggi sehingga sulit terurai. Penambahan cendawan selulolitik digunakan untuk mempercepat proses dekomposisi karena kemampuannya dalam menghasilkan enzim pemecah substrat karbohidrat tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan cendawan selulolitik terhadap laju dekomposisi, mendapatkan satu perlakuan terbaik, dan mengetahui korelasi rasio C/N, sisa bobot, suhu, pH, dan kadar air dengan konstanta kecepatan dekomposisi. Perlakuan yang diujikan yakni (K1) kontrol, (K2) pemberian cendawan Cunninghamella sp., (K3) pemberian cendawan Trichoderma sp., dan (K4) pemberian kombinasi kedua cendawan tersebut. Percobaan perlakuan dilakukan sebanyak 4 ulangan, dan 3 kali pengamatan yang dilakukan setiap 3 pekan sekali. Hasil penelitian menunjukkan bahwa pemberian cendawan selulolitik mempercepat penurunan rasio C/N dan sisa BKO pada kompos serasah dan blotong tebu, laju dekomposisi terjadi lebih cepat pada 3 pekan pertama, dan terjadi korelasi negatif antara rasio C/N, sisa BKO dan suhu dengan konstanta laju dekomposisi (k) serta terdapat korelasi positif antara pH dan kadar air dengan konstanta laju dekomposisi (k). Perlakuan terbaik terdapat pada penambahan kombinasi cendawan Cunninghamella sp., dan Trichoderma sp.

Abstract

Anthracnose is a major disease of chili peppers caused by complex of Colletotrichum species. Intensive application of fungicides is the main choice for control anthracnose. This study aimed to evaluate the sensitivity of Colletotrichum spp. to fungicides and determine the effective concentration to control Colletotrichum spp. This study was conducted from March to July 2024 at the Plant Disease Laboratory, Faculty of Agriculture, Lampung University. Anthracnose pathogens were isolated from Tegineneng District, Pesawaran Regency, Lampung Province. Sensitivity tests were conducted using the recommended concentration with poisoned food techniques. The effective concentration determination test was carried out only on fungicides that showed a resistance response using the poisoned food technique. The fungicides tested were those used by farmers in the location where the samples were taken. The sensitivity test results showed that the fungus Colletotrichum spp. from Tegineneng District was highly resistant to propineb. Colletotrichum spp. from locations 3 and 4 are still sensitive to carbendazim, but from locations 1 and 2 are resistant. Colletotrichum spp. from locations 2, 3, and 4 were still very sensitive to mankozeb, while those from location 1 were moderately resistant. The effective concentration of propineb for locations 1, 3, and 4 was 5x the recommended concentration, and for location 2 was 4x the recommended concentration. The effective concentration of carbendazim for location 1 was 5x the recommended concentration, and for location 2 was 2x the recommended concentration. The effective concentration of mancozeb fungicide at location 1 was 2x the recommended concentration.

Abstract

Seed quality is a critical factor in achieving optimal crop yield. Cayenne pepper (Capsicum frutescens L.) seeds are widely obtained through marketplaces; however, information on seed-borne microorganisms associated with commercially sold seeds remains limited. This study aimed to detect and identify microorganisms carried by cayenne pepper seeds marketed through local marketplaces. In this research, five seed varieties obtained from the marketplace were examined, namely KSD 108, Top Garden Seed, Red Cluster Pepper, Raja, and Home Garden. Seed health testing was performed using seed washing, blotter paper incubation, and agar plate methods. Observed variables included seed germination percentage, incidence of microbial infection, fungal identification based on microscopic characteristics, and bacterial identification using the 3% KOH Gram test, soft rot assay, and hypersensitive reaction test. Data were analyzed descriptively and presented in tables and figures. The results showed that uncertified seeds—Top Garden Seed, Red Cluster Pepper, Raja, and Home Garden—were contaminated by various seed-borne microorganisms, predominantly Aspergillus niger, A. fumigatus, A. tamarii, Fusarium oxysporum, and F. verticillioides. Gram-negative bacteria were also detected. In contrast, certified seeds contained A. niger and Gram-positive bacteria.
