Abstract

Castor oil (Ricinus communis L.) is an oil producing commodities that plays a role in meeting industrial and economic needs. Infection with the pathogen fungi caused a decrease in the production of castor oil. Biological control using Trichoderma spp. has been widely used. Trichoderma spp. known as one of the benefical biofungicide because it has high antagonistic properties inhibiting the growth pathogenic fungi. The purpose of this study was to obtain isolates and characters as well antifungal test for Trichoderma spp. isolated from peat soil to control pathogen Aspergillus sp. on castor been (Ricinus communis L.). Trichoderma spp. isolated from peat soil in Meranti Islands, Riau. The antagonistic activity the isolates against pathogen Aspergillus sp. was studied in vitro using dual culture and in vivo assay. In this study, six isolates of Trichoderma spp have isolated. Trichoderma sp. GBA5 has the highest growth rate on PDA and TSM medium. Trichoderma sp. GBA3 and Trichoderma sp. GBA4 were most effective in percentage inhibition of mycelial growth of test pathogen i.e 84,55%  and 83,71% respectively. In in vivo assay, only Trichoderma sp. GBA5 inhibited pathogen with the percent infected castor capsule was 51.66%.

Abstract

Bakteri pelarut fosfat dari tanah gambut asal Sei. Garo telah diuji potensinya padamedium Pikovskaya dan tanah PMK. Delapan isolat berhasil didapatkan, 3 diantaranya memilikikriteria tinggi melarutkan fosfat. Isolat dengan kriteria tinggi dan campurannya diuji potensinya dalampenyediaan fosfat pada medium Pikovskaya cair dan tanah PMK. Kemampuan tertinggi melarutkanfosfat pada medium Pikovskaya cair adalah isolat GGO1 (I1) yaitu 0,4736%. Secara keseluruhan adakecenderungan bahwa inokulum memiliki kemampuan dalam penyediaan fosfat pada tanah PMKnamun hasil menunjukkan tidak ada interaksi antara tanah dan inokulum terhadap kandungan fosfattersedia tanah dan serapannya pada tanaman. Perlakuan tanah tanpa sterilisasi berpengaruh nyataterhadap kandungan fosfat tersedia tanah.
