Daftar Isi:
- Penyakit busuk bulir padi yang disebabkan oleh Bulkholderia glumae merupakan penyakit penting yang dapat ditularkan melalui benih padi. Berbagai teknik pengendalian penyakit busuk bulir padi telah dikembangkan untuk mencegah kehilangan hasil panen, salah satunya menggunakan asap cair. Asap cair banyak dikaji sebagai agens pengendalian berbagai penyakit tanaman. Penelitian ini bertujuan menentukan potensi asap cair untuk pengendalian penyakit busuk bulir padi yang disebabkan oleh B. glumae dan sebagai pemacu pertumbuhan bibit padi. Tahapan penelitian terdiri atas: uji potensi asap cair terhadap B. glumae, uji fitotoksisitas asap cair dan pengaruhnya terhadap pertumbuhan benih padi, serta uji keefektifan asap cair dalam menekan B. glumae pada benih terinfeksi. Hasil penelitian menunjukkan bahwa asap cair dengan konsentrasi 2% dapat menekan perkembangan B. glumae secara in-vitro dan tidak menyebabkan fitotoksisitas pada benih padi dengan indeks vigor 90% dan daya berkecambah 90% dibandingkan dengan kontrol dengan nilai indeks vigor dan daya berkecambah sebesar 76% dan 83%. Asap cair dengan konsentrasi 2% juga dapat menekan keparahan penyakit pada fase pembibitan dengan tingkat hambatan relatif 43.8%. Adapun nilai panjang plumula bibit padi pada perlakuan asap cair 2% ialah sebesar 5.87 cm. Nilai plumula tersebut lebih besar dibandingkan dengan kontrol yang hanya sebesar 5.22 cm. Berbeda dengan plumula, nilai panjang radikula tidak mengalami peningkatan signifikan dibandingkan dengan kontrol.
- Liquid smoke to Control Bulkholderia glumae and Growth Promoter of Rice Seeds Bacterial grain rot disease caused by Bulkholderia glumae is an important disease that can be transmitted through rice seeds. Various bacterial grain rot disease control techniques have been developed to prevent crop loss, one of which is liquid smoke. Liquid smoke has been widely studied as an agent for controlling various plant diseases. The aim of the study was to determine the potential of liquid smoke to control bacterial grain rot disease caused by B. glumae and to promote the growth of rice seedlings. Research was conducted in some stages, included: potential test of liquid smoke against B. glumae, phytotoxicity test of liquid smoke and its effect on rice seed growth; and test the effectiveness of liquid smoke in suppressing B. glumae on infected seeds. The results showed that liquid smoke with a concentration of 2% could suppress the development of B. glumae in vitro and did not cause phytotoxicity in rice seeds with a vigor index of 90% and germination of 90% compared to controls with a vigor index value and germination value of 76% and 83%. Liquid smoke with a concentration of 2% can also reduce the severity of disease in the nursery phase with a relative inhibition level of 43.8%. The value of the length of the plumule of rice seedlings in the 2% liquid smoke treatment was 5.87 cm. The plumule value was greater than the control which was only 5.22 cm. In contrast to the plumula, the value of radicular length did not increase significantly compared to the control.
