Abstract

Soil microbes associated with rhizosphere are important for promoting plant growth and inducing resistance to diseases. The research was conducted to study the ability of Trichoderma spp. and Penicillium spp. isolated from rhizosphere in lowland swampy area for controlling damping-off disease caused by Rhizoctonia solani Khun. Trichoderma spp. and Penicillium spp. were cultured in bran, corn meal, and rice straw containing media and applied as inoculum to 2-weeks old seedlings. Application of two fungi isolates effectively induced resistance of chili plants to damping-off disease. Trichoderma spp. and Penicillium spp. were significantly reduced disease incidence by 61.5–100% to 46.2–100%, respectively and disease severity by 50–100% and 30–95.9%, respectively. This experiment showed the potential of Trichoderma spp. and Penicillium spp. as biocontrol agents to control damping-off disease on chili.

Abstract

Damping-off disease is commonly occurred in chili pepper field and always caused significant effect on chili production. This experiment was conducted to determine the ability of 14 isolates of Trichoderma isolated from lowland swampy area in South Sumatera against damping-off disease. The result showed that treatment of Trichoderma significantly inhibited damping-off disease caused by Rhizoctonia solani. Treatment of Trichoderma effectively reduced the percentage of pre-emergence damping-off, post-emergence damping-off, and disease severity by 51.8–100%, 80–100%, and 51.90–96.96%, respectively. The treatment was also capable to increase percentage of height and fresh weight of chili pepper seedling, i.e. 45.45–64.37% and 37.78–81.19%, respectively.
