“…Eucalyptus oil, as well as Melaleuca and Rhodamnia extract can inhibit several types of pathogens such as bacteria and fungi that attack plant commodities, besides as inhibitors of microorganisms that cause disease humans and animals. Some interesting examples include Pectobacterium carotovorum (formerly classified as Erwinia carotopora) which is a pathogen on cabbage, tomatoes, eggplant, and nepenthes (Lee et al 2014), Xanthomonas axonopodis on citrus (Petrocelli et al 2012), X. campestris on cruciferous plants (Vicente and Holub 2013), X. oryzae on rice (Lang et al 2019), Fusarium oxysporum on banana (Maymon et al 2020), F. solani on guava (Ingle 2017), Agrobacterium tumefasciens causing crown galls and hairy roots of over 20 different fruit trees (Smith and Townsend 2019), Ralstonia solanacearum on potato (Álvarez et al 2019), Rhizoctonia solani (teleomorph: Thanatephorus cucumeris) on sugar beet (Windels et al 1997), and Colletotrichum capsici on chili (Saxena et al 2016). Thus, it is also expected to protect the collection of nepenthes and another plant collection belonging to CBG.…”

Abstract. Pratiwi RA, Nurlaeni Y. 2021. The potency of Myrtaceae Family from Cibodas Botanic Gardens (Cianjur, Indonesia) as botanical pesticide. Biodiversitas 22: 4648-4664. Cibodas Botanic Gardens (CBG) is a biodiversity reservoir that can be explored for the discovery of new candidates for botanical pesticides. Myrtaceae has been reported to provide biological activity against pests or pathogens due to their essential oil contents. This research was conducted to inventory and categorize Myrtaceae collection in CBG that had the potency to be botanical pesticide. The list of Myrtaceae collection of CBG obtained from Unit Registration and Collection CBG per 2021. Database fulfilling regarding the bactericide/fungicide/herbicide/insecticide potency of the Myrtaceae of CBG’s collection was carried out through digital references search. Our result showed that there were 73 species of Myrtaceae (from 18 genera) that are potential to be botanical pesticide sources. There were 17 species that are considerably had a high potency. Most of them belong to the Eucalyptus and Melaleuca, followed by Backhousia, Leptospermum, Psidium, and Syzygium. The data resulted from this study is expected to serve as baseline information for further research about the formulation, efficacy, and conservation management of botanical pesticides from Myrtaceae for sustainable use. Furthermore, the development of biological pesticides is a step to improve the quality of Indonesian export products so as to increase national competitiveness in the globalization era nowadays.

“…Tahap berikutnya melakukan pemurnian jamur-jamur yang tumbuh dari hasil isolasi, yaitu memisahkan berbagai jamur yang tumbuh pada cawan petri. Jamur hasil pemurnian diamati diameter pertumbuhan koloni setiap hari hingga 7 hari setelah pemurnian (Ingle, 2017;Kalman et al, 2020;Akhsan et al, 2021;Irfandi et al, 2022). Identifikasi jamur dilakukan dengan mengamati karakteristik morfologis secara makroskopis, meliputi warna permukaan atas, warna permukaan bawah dan tekstur permukaan koloni (Barnett dan Hunter, 1998;Amanda et al, 2017;Ingle, 2017;Irfandi et al, 2022).…”

Salah satu faktor pembatas budidaya bawang merah (Allium ascalonicum L.) adalah serangan patogen yang mampu menurunkan hasil produksi bawang merah. Penggunaan bawang merah asal biji (true shallot seed) varietas Lokananta untuk produksi umbi belum banyak dilakukan, sehingga informasi jenis penyakit yang menyerang belum banyak dilaporkan. Tujuan penelitian ini untuk mengetahui gejala dan tanda penyakit, serta jenis patogen pada tanaman bawang merah varietas Lokananta. Penelitian dilakukan menggunakan metode survei. Lokasi survei dilaksanakan di Kabupatan Sleman dan Bantul, Provinsi Daerah Istimewa Yogyakarta. Inventarisasi penyakit dilakukan dengan pengamatan langsung di lapangan terhadap gejala serangan patogen pada daun, umbi maupun akar tanaman bawang merah secara acak. Tahap isolasi dan karakteristik makroskopis dilakukan di laboratorium. Hasil penelitian menunjukkan dua jenis penyakit utama pada tanaman bawang merah varietas Lokananta yaitu penyakit moler yang disebabkan oleh jamur Fusarium sp. dan antraknosa (busuk daun) yang disebabkan oleh jamur Colletotrichum gloeosporioides. Gejala khas moler yaitu daun menguning cenderung melengkung terpelintir (terputar), tanaman menjadi layu dan terkulai, serta umbi membusuk. Gejala awal antraknosa yaitu bercak putih berbentuk lonjong hingga bulat pada daun dan terbentuk cekungan. Gejala lebih lanjut daun akan patah dan terkulai, serta terbentuk koloni konidia kehitam-hitaman. Hasil isolasi dari tanaman bawang merah varietas Lokananta diperoleh dua isolat jamur Fusarium sp. dan satu isolat jamur C. gloeosporioides. Karakteristik makroskopis tampak bawah permukaan cawan petri dua isolat Fusarium sp. dan satu isolat C. gloeosporioides berturut-turut yaitu ungu, jingga dan abu-abu. Penelitian ini mengonfirmasi jenis penyakit pada tanaman bawang merah varietas Lokananta sebagai informasi dasar dalam menentukan cara pengendalian penyakit yang tepat sasaran.

“…More specifically, we compare the antimicrobial activity of the SLC Cu-BTC MOFs with that of the 3D cubic Cu-BTC MOFs (HKUST-1) and a commercial copper pesticide against a model bacterium Pseudomonas syringae (P. syringae), fungus Fusarium solani (F. solani), and virus Odontoglossum ringspot virus (ORSV), all of which are known to commonly infect economically important crops, including fruits, vegetables, and ornamental plants. 30,31 The efficacy of these three copperbased compounds was further investigated as a prophylactic for orchid potted plants against ORSV and as a treatment for controlling the spread of ORSV in infected plants. In addition to the phenotypic observation of the dark ring spots on the treated infected leaves and examination of their necrotic area to assess phytotoxicity, we carry out quantitative polymerase chain reaction (qPCR) to estimate the viral load in the leaves.…”

Metal−organic frameworks (MOFs) have recently been shown to be effective antimicrobial agents, particularly if they comprise pathogenicidal metal ions. Nevertheless, the accessibility of these active metal sites to the pathogen, and hence the MOFs' antimicrobial activity itself, is often poor since the metal nodes are usually embedded deep within its three-dimensional (3D) structure. We show that a unique copper-based (copper(II)-benzene-1,3,5-tricarboxylate) MOF, whose quasi-two-dimensional (quasi-2D) swordlike structure facilitates exposure of the metal ions along its surface, exhibits enhanced antimicrobial properties against three representative plant pathogens: a bacterium (Pseudomonas syringae), a fungus (Fusarium solani), and a virus (Odontoglossum ringspot virus (ORSV)). Such superior antimicrobial activity results in low minimum inhibitory concentrations (MICs)half that of a commercial pesticide and an eighth of its conventional 3D cubic MOF counterpart (HKUST-1)and hence low phytotoxicity, which can be attributed to the accessibility of the surface copper sites to the pathogen, thereby facilitating their adhesion and physical contact with the MOF. Additionally, we observed that orchids treated with the quasi-2D MOF showed negligible phytotoxicity and 80% decreased viral load. This work constitutes the first study to demonstrate the antimicrobial properties of this novel MOF against bacterial, fungal, and viral plant pathogens, and the first chemical control of ORSV.
