Uji efektivitas Trichoderma sp. terhadap Fusarium bubalinum penyebab penyakit busuk pelepah padi
Abstract
Fusarium bubalinum is a pathogen associated for rice sheath rot, a disease characterized by reddish-brown necrotic lesion and the rotting of leaf sheaths. In severe cases, this disease may prevent rice panicles from emerging completely, resulting in unfilled grains. Trichoderma sp. has potential as a biological control agent against this disease. This study aimed to determine the effect of temperature on the growth of Trichoderma sp. and to evaluate its antagonistic activity againts of F. bubalinum, the causal agent of rice sheath rot. The study consisted of two experiment: an assessment of Trichoderma sp. growth at different temperatures and evaluation of its antagonistic activity againts F. bubalinum. The results showed that Trichoderma sp. exhibited the highest growth at 30°C. Furthermore, Trichoderma sp. inhibited the growth of F. bubalinum by up to 88.69% in dual-cultureassay and 60.60% in double-dish assay.
