Abstract

Phytophthora dan Pythium merupakan kelompok Oomycetes yang banyak berasosiasi dengan penyakit pada tanaman kentang. Penelitian ini bertujuan untuk mengidentifikasi Oomycetes yang berasosiasi dengan rizosfer kentang yang menunjukkan gejala penyakit hawar daun. Empat isolat berhasil dikoleksi dari empat wilayah sentra pertanaman kentang di Jawa Tengah (isolat UGM_St_TM, UGM_St_BK , UGM_St_BNJ , dan UGM_St_KJ berturut-turut dari Temanggung, Bakal, Banjarnegara dan Kejajar) dan satu isolat UGM_St_NG koleksi dari Laboratorium Ilmu Penyakit Tumbuhan. Identifikasi molekuler dari semua isolat dilakukan menggunakan penanda gen internal transscribed spacer (ITS1/ITS4), Nuclear large-ribosomal subunit (LSU), dan cytochrome C oxidase subunit 1 (COX1). Berdasarkan hasil penelitian, isolat UGM_St_TM, UGM_St_BK, dan UGM_St_BNJ teridentifikasi sebagai Phythium ultimum sedangkan isolat UGM_St_KJ dan UGM_St_NG teridentifikasi sebagai Phytopythium vexans.

Abstract

Penyakit blas merupakan salah satu penyakit penting yang dapat menyebabkan kehilangan hasil pada tanaman padi. Pengendalian penyakit dengan menggunakan varietas tahan dan penggunaan fungisida masih belum efektif karena tingginya variasi genetik patogen blas, yaitu cendawan Pyricularia oryzae. Pengendalian hayati di antaranya menggunakan cendawan endofit diharapkan mampu menjadi alternatif untuk menekan P. oryzae. Penelitian ini bertujuan menguji aplikasi perendaman dan penyemprotan cendawan endofit Nigrospora sp. dalam menekan penyakit blas. Percobaan dilakukan di dalam pot yang diletakkan di lapangan terbuka di Bogor dari bulan Februari sampai Oktober 2021. Aplikasi cendawan endofit yang diujikan meliputi perendaman benih, penyemprotan tajuk dan kombinasi keduanya. Sebagai pembanding digunakan tanaman yang diberi perlakuan fungisida berbahan aktif trisiklazol dan tanaman kontrol yang tidak diberi perlakuan. Pengamatan meliputi insidensi penyakit, keparahan penyakit dan kolonisasi cendawan endofit pada potongan daun. Meskipun insidensi penyakit mencapai 100% untuk semua perlakuan pada pengamatan terakhir (7 minggu setelah inokulasi), namun tingkat keparahannya tertekan oleh perlakuan Nigrospora sp. Cendawan endofit Nigrospora sp. mampu menekan keparahan penyakit blas daun sebesar 3.0%–25.3% dan blas leher sebesar 49.5%–61.6% jika dibandingkan dengan kontrol. Penekanan penyakit blas paling stabil mulai dari awal pengamatan sampai akhir pengamatan ditunjukkan oleh perlakuan kombinasi perendaman benih dengan penyemprotan Nigrospora sp. Kemampuan cendawan endofit dalam mengolonisasi tanaman padi pada perlakuan Nigrospora sp. berkisar 40.0%–55.6%.

Abstract

Characterization of Soil Rhizospheric Fungi on Citrus Plantation and Their Potential to Inhibiting the Growth of Botryodiplodia theobromae and Colletotrichum gloeosporioidesThe rhizosphere soil around the roots of citrus plants has microorganisms, one of which is a fungus. The aim of this study was to identify the rhizosphere fungi of Siam Pontianak organic citrus gardens and their potential to inhibit the growth of the pathogenic fungi Botryodiplodia theobromae and Colletotrichum gloeosporioides. The characterization of the fungus was carried out by evaluating its growth at different temperatures, humidity and pH levels, then an antagonist test was performed on C. gloeosporioides and B. theobromae. The fungi obtained from the rhizosphere of Siam Pontianak citrus organic farming were Fusarium sp., Fusidium sp., Penicillium sp., Trichoderma sp. All rhizosphere fungi grow optimally at pH 4.5–5.5, temperature 20–30 ℃ and humidity 60–80%. The fungus Penicillium sp. had the highest ability to inhibit the growth of C. gloeosporioides (83.66%), while Trichoderma sp. able to inhibit the growth of the highest pathogen B. theobromae (92.04%). Further studies are needed before applying the obtained fungal isolates as biocontrol agents for C. gloeosporioides and B. theobromae.

Abstract

Nematoda puru akar (NPA) Meloidogyne spp. merupakan salah satu patogen penting pada tanaman terung. Puru akar sangat merugikan karena menurunkan hasil produksi. Penelitian ini bertujuan mendapatkan bakteri endofit dari Lantana camara dan mengevaluasinya bersama bakteri endofit dari akar kelapa sawit, dan mangrove yang berpotensi untuk mengendalikan Meloidogyne spp. dan menentukan pengaruhnya pada pertumbuhan tanaman terung, serta mengidentifikasi bakteri endofit yang potensial sebagai agens pengendalian hayati. Potensi agens hayati mengacu pada hasil pengujian uji mortalitas, uji senyawa organik volatil (SOV) dan uji penekanan puru akar dievaluasi dengan mengukur persentase penurunan jumlah puru, kerusakan akar, dan jumlah paket telur. Hasil uji menunjukkan seluruh isolat bakteri endofit berpotensi menyebabkan mortalitas, menghasilkan SOV, dan dapat menekan persentase jumlah puru pada akar, serta memberikan pengaruh terhadap bobot dan tinggi tanaman. Bakteri endofit LCA5 dan LCA13 menyebabkan mortalitas lebih dari 90% terhadap Meloidogyne spp. J2. Selama 24 jam dan pada uji SOV menyebabkan mortalitas lebih dari 60% selama 24 jam. Bakteri endofit yang memiliki potensi sebagai pengendalian hayati diidentifikasi sebagai Dyella marensis, Stenotrophomonas rhizophilla, dan Providencia vermicola.

Abstract

The Severity of Fusarium Wilt Disease in Correlation to the Abundance of Fusarium oxysporum and Phytonematodes: Case Study at Banana Plantation PTPN VIII Parakansalak Fusarium oxysporum f. sp. cubense is a soil-borne pathogen that infects banana plants and causes wilt. Several studies demonstrated that phytomatodes have a role in helping infection of the pathogens that cause wilt. This study aims to determine the relationship between phytonematodes and Fusarium oxysporum f. sp. cubense from soil and banana roots infected with fusarium wilt. Soil samples was obtained from infected banana plants and collected based on different scores of fusarium wilt disease severity. Samples were then composited based on the score, and the abundance of each pathogen is measured following samples extraction in the laboratory. The highest population of phytonematodes was 77 g-1 obtained from soil with a disease severity score of 4; and the lowest was 16 g-1 from samples with a score of 2. As for root samples, the highest population of phytonematodes (85 g-1) was obtained from plants with a score 0 and the lowest (33 g-1) was from plants with a score 3. Two species of phytonematodes were identified, i.e. Helicotylenchus sp. and Radopolus sp. Based on measurement using conventional methods showed that the abundance of Fusarium oxysporum f. sp. cubense was highest in plants with a score of 1, i.e. 8.1 × 103 cfu g-1 soil and lowest in plants with a score of 0 i.e. 1.0 × 103 cfu g-1 soil. The effect of Fusarium oxysporum f. sp. cubense to the severity of fusarium wilt shows a positive relationship of 8.3% and it may contribute to cause fusarium wilt disease by 0.6%. This pathogen can cause wilting of bananas without the help of the phytonematode species found in this study.
