Abstract

Meloidogyne spp. merupakan nematoda parasit penting pada berbagai tanaman yang menyebabkan gejala penyakit seperti puru akar, kerdil, daun menguning, dan tanaman menjadi layu. Nematisida botani memiliki potensi menjanjikan sebagai metode pengendalian nematoda. Penelitian ini bertujuan mengetahui potensi Rorippa indica sebagai biofumigan dalam mengendalikan nematoda puru akar (Meloidogyne incognita). Percobaan biofumigasi dilakukan melalui 2 tahapan, yaitu percobaan laboratorium dan rumah kaca dengan masa inkubasi selama 14 hari untuk proses biofumigasi. Percobaan di laboratorium menggunakan polibag berisi 100 g tanah yang diinfestasi 100 juvenil 2 (J2) M. incognita sebelum perlakuan biofumigasi. Potongan batang, daun, dan seluruh bagian tumbuhan R. indica dicampurkan pada polibag dengan bobot bahan 1.3, 2.3, dan 3.9 g sebagai perlakuan. Percobaan di rumah kaca dilakukan dengan menambahkan potongan R. indica dengan bobot bahan 150 g per polibag yang berisi 3 kg tanah dan telah diinfestasi 300 J2 M. incognita. Tanaman mentimun berumur 7 hari setelah semai dipindahkan ke dalam polibag yang telah dibiofumigasi dan diamati selama 6 minggu. Hasil pengujian menunjukkan bahwa biofumigasi menggunakan R. indica dalam skala laboratorium terbukti efektif mengurangi populasi nematoda sebesar 87%, sedangkan pada skala rumah kaca menyebabkan perbedaan pembentukan puru yang signifikan dibandingkan perlakuan kontrol. Hal ini berkaitan dengan hasil analisis GC-MS yang menunjukkan kandungan terpenoid pada ekstrak R. indica. Perlakuan R. indica dapat meningkatkan pertumbuhan tanaman mentimun dibandingkan kontrol.

Abstract

Effects of Rice Endophytic Bacteria on Bacterial Grain Rot Disease and Rice Growth Bacterial grain rot disease, caused by Burkholderia glumae, is an important disease that can reduce rice yields and is a seed-borne disease. Biological control through biopriming using endophytic bacteria is an alternative disease control method that has been widely used in various crops. This study aimed to assess the potential of endophytic bacteria from six rice varieties using biopriming techniques in controlling B. glumae and their ability to stimulate rice growth. The research stages consisted of isolation and biosafety testing of endophytic bacteria with potential as biological agents, in vitro antagonism assay against B. glumae using the cross streak method, phytotoxicity assay of endophytic bacteria on rice seeds, selection of potential bacteria using the analytical hyphenation process (AHP) method, and examining the ability of biopriming to control B. glumae and its effect on rice vegetative growth. A total of 133 endophytic bacterial isolates were successfully isolated from six rice varieties, and 27 isolates met the biosafety test requirements. In vitro and in vivo assay showed that eight isolates exhibited antagonistic activity against B. glumae, and 25 isolates increased rice seed germination. Three isolates were selected based on AHP results, i.e. BBZN3, BBAR4, and AKPAT4. Of these three isolates, AKPAT4 was the best at increasing the vigor index and germination level of rice seeds, as well as suppressing disease incidence and severity.
