Abstract

Fungicidal activity of garlic (Allium sativum) bulbs extracts against plants phatogenic fungi. Garlic (Allium sativum Linn) has been known to containing organosulphur compounds. These compounds are convinced to possess antibacterial, antifungal, and anticancer activities. The aim of this study is to determine fungicidal activity of garlic bulb extracts against some plants phatogenic fungi. The paper disc agar difussion technique was used to determine fungicidal activity of garlic bulbs extracts. The results showed that in general garlic bulbs extracts provides fungicidal activities. Calculated EC50 values indicated that ethyl acetate garlic bulbs extract was most active against Colletotrichum capsici, Fusarium oxysporum f. sp.capsici, and Sclerotium rolfsi by EC50 values of 48,6; 50,3; and 51.3% respectively. Meanwhile methanolic garlic bulbs extract was the most active against Sclerotium rolfsi with EC50 values of 24,3%.

Abstract

Penyakit budok yang disebabkan oleh Synchytrium pogostemonis merupakan masalah utama pada budi daya nilam di Provinsi Aceh (Pogostemon cablin). Tujuan penelitian ini ialah untuk mendapatkan cara pengendalian S. pogostemonis dengan menggabungkan kompos limbah ampas nilam (LAN), mikrob antagonis, dan minyak atsiri sebagai anticendawan. Penelitian dibagi menjadi dua tahap. Tahap pertama ialah pengujian efek penambahan kompos LAN terhadap pertumbuhan tanaman nilam. Tiga spesies mikrob antagonis, yaitu Trichoderma harzianum (ThC6), T. asperellum (TaC1), dan Pseudomonas aureginosa (AJ14) diinokulasikan pada LAN sebagai biodekomposer sekaligus agens antagonis baik secara tunggal maupun kombinasi. Kompos LAN diaplikasikan pada medium tanam sebelum penanaman setek nilam dengan dua taraf rasio tanah dan kompos LAN (1:1 dan 1:2). Parameter yang diamati ialah pertumbuhan tanaman nilam meliputi tinggi tanaman dan jumlah daun. Pada tahap kedua diamati pengaruh kombinasi kompos LAN dan minyak atsiri terhadap keparahan penyakit budok. Minyak atsiri yang digunakan adalah minyak atsiri serai wangi dan nilam dengan konsentrasi 0.5% dan 1%. Hasil penelitian menunjukkan bahwa penambahan mikrob antagonis baik secara tunggal maupun kombinasi pada LAN dapat meningkatkan tinggi batang dan jumlah daun tanaman nilam masing-masing sebesar 22% dan 38%. Keparahan penyakit terendah ditunjukkan oleh perlakuan kombinasi kompos LAN dan 1% minyak atsiri serai wangi, yaitu sebesar 10%.

Abstract

Shallot (Allium cepa) is an economically valuable and highly nutritious crop whose productivity can be increased through optimal cultivation practices. This study investigated the combined effects of mulch and liquid organic fertilizer (LOF) on onion yield and performance. A factorial randomized block design (RCBD) was used consisting of two factors, namely mulch type (no mulch, black and silver plastic mulch, rice husk mulch, and shallot skin mulch) and LOF dosage (no LOF, 1,000 L/ha, and 1,500 L/ha). Data were analyzed using Least Significant Difference (LSD) and Duncan's Multiple Range Test (DMRT) at = 5%. The application of rice husk mulch and LOF at a dose of 1,500 L/ha resulted in the highest number of bulbs, bulb diameter, wet weight, dry weight, soil microbial population, and peroxidase enzyme activity among all treatments. This study demonstrates that rice husk mulch and LOF at a dose of 1,500 L/ha can significantly enhance shallot production. Additionally, the findings indicate that the use of rice husk mulch and LOF at a dose of 1,500 L/ha can boost soil microbial population and increase peroxidase enzyme activity.

Abstract

Aceh Patchouli (Pogostemon cablin Benth.) is a significant export commodity for essential oil production in Indonesia. The wilt disease “matee tumbon” caused by Enterobacter bacteria is one of the obstacles to Aceh patchouli cultivation. This study aims to identify the most effective combination technique to control it. The study combined 25 treatment combinations in patchouli nurseries, and the five best treatment combinations were subsequently tested on patchouli plants in the field. The results showed that the five best combinations in controlling bacterial wilt disease in the nursery were 20% streptomycin sulfate + Trichoderma sp., 20% streptomycin sulfate + Bacillus thuringiensis, Trichoderma sp. + B. thuringiensis, 20% streptomycin sulfate + neem extract + B. thuringiensis, and neem extract + Trichoderma sp. + B. thuringiensis. Field results showed that the combination of neem extract, Trichoderma sp., and B. thuringiensis was effective in controlling the pathogen Enterobacter sp., causing bacterial wilt disease in Aceh patchouli plants. This combination of control techniques is an integrated approach to controlling bacterial wilt disease (Enterobacter sp.) in Aceh patchouli plants.
