<![CDATA[Soybean production in Indonesia in 2022 will only be able to meet 5% of soybean consumption needs. Import traffic for this commodity increases the risk of Peronospora manshurica. P. manshurica is a quarantine plant pest organism that causes downy mildew epidemics. Hoyer's solution is known to increase the shelf life of characterization results, thereby increasing time and energy efficiency in quarantine activities. The problem formulation for this activity is how to characterize the results of imported soybeans using Hoyer's solution. This activity aims to analyze the results of the characterization of imported soybeans using Hoyer's solution. Characterization of imported soybeans is done by direct test with the following stages: 1) administrative inspection, 2) sampling of imported soybean seeds, and 3) direct test. The observation results showed the presence of P. manshurica. The imported soybeans were proven to be infected with P. Manchuria, which visually had greyish-white crusty seed coats. Hoyers' solution effectively extends the life of preparations and is efficient because P. Manchuria is difficult to identify and cannot be grown on culture media. The discovery of fungi-like white crust symptoms on imported soybeans became the basis for the Animal, Fish, and Plant Quarantine Center's decision to provide fumigation or heating treatment to 80°C before distributing the commodity.]]>
