The present invention relates to a stem blight pest control composition including a Phytolacca americana L. leaf extract or fraction as an active ingredient. According to the present invention, a methanol extract is obtained by extracting a Phytolacca americana L. leaf with a methanol aqueous solution as a solvent, and concentrating the same under reduced pressure. After the methanol extract is suspended with water, a fraction layer obtained by sequentially distributing and extracting the methanol extract with nucleic acid, ethylacetate, and a butanol solvent is concentrated under reduced pressure to secure fractions. An ethylacetate fraction and a butanol fraction thereamong are confirmed to have antimycotic activity with respect to Leucostoma persoonii, one of causative organisms of stem blight, and the ethylacetate fraction is confirmed to have excellent antimycotic activity. |
