Daftar Isi:
- Red pepper is agricultural products in Indonesia which is often attacked by fusarium wilt disease due to the fungus Fusarium oxysporum f.sp. capsici, so in this study aims to control of fusarium wilt disease using Trichoderma asperellum TKD with mediator of manure. Method in this study is RAL (Completely Randomized Design) with 7 treatments P1 = Control I (without treatment); P2 = Control II (F.oxysporum f.sp. capsici (disease)); P3 = disease + T. asperellum TKD 10 mL; P4 = disease + T. asperellum TKD 20 mL; P5 = disease + T.asperellum TKD 30 mL; P6 = disease + T. asperellum TKD 40 mL; P7 = disease + T. asperellum TKD 50 mL. The results showed that T.asperellum TKD was able to inhibit F.oxysporum f.sp. capsici in in vitro by 100%. The highest percentage of fusarium wilt disease (100%) is shown in plants that are only given F.oxysporum f.sp. capsici and without T. asperellum TKD, as well as plant height, total of fresh and dried leaves in plants added by T. asperellum TKD is better compared to plants that are not given T. asperellum TKD. The best plant height, number of freh leaves, and lowest number of dry leaves found in plants with 50 mL of T.asperellum TKD. Keywords: biocontrol, pathogenic fungi, Trichoderma asperellum TKD
- Cabai merah merupakan hasil pertanian di Indonesia yang sering terserang penyakit layu fusarium akibat F. oxysporum f.sp. capsici, sehingga dalam penelitian dilakukan pengendalian penyakit layu fusarium dengan menggunakan jamur T. asperellum TKD dan mediator pupuk kandang. Metode yang digunakan rancangan acak lengkap dengan 7 perlakuan P1 = Kontrol I (tanpa perlakuan); P2 = Kontrol II (F.oxysporum f.sp. capsici (penyakit)); P3 = penyakit + T.asperellum TKD 10 mL; P4 = penyakit + T.asperellum TKD 20 mL; P5 = penyakit + T.asperellum TKD 30 mL; P6 = penyakit + T.asperellum TKD 40 mL; P7 = penyakit + T.asperellum TKD 50 mL. Hasil menunjukkan T.asperellum TKD mampu menghambat F.oxysporum f.sp. capsici sebesar 100%. Penyakit layu fusarium (100%) terdapat pada tanaman yang hanya diberikan F.oxysporum f.sp. capsici serta tanpa T. asperellum TKD. Perlakuan yang ditambahkan T.asperellum TKD menunjukkan pertumbuhan tinggi tanaman, jumlah daun segar dan kering lebih baik daripada tanpa T.asperellum TKD. Tinggi tumbuhan dan total daun terbaik, serta total daun kering terendah terdapat di perlakuan dengan diberikan T.asperellum TKD 50 mL.
