Information about the diversity and density of parasitic nematode populations in sugarcane has not been widely reported, especially in West Sumatra. This information is very important to determine the initial steps to prevent parasitic nematode attacks, reduce the risk of damage and loss of yield due to sugarcane nematodes. The purpose of this study was to determine the types of parasitic nematodes and their populations in the sugarcane rhizosphere. Soil samples were taken from the sugarcane rhizosphere in West Sumatra sugarcane production centers, namely Agam and Tanah Datar. The research included soil extraction and nematode observations carried out in the Nematology Laboratory of the Department of Pests and Plant Diseases, Faculty of Agriculture, Andalas University. The extraction method used a combination of modified Baermann Funnels and stratified soil filters. Identification is based on specific, anterior and posterior forms. The results obtained 6 parasitic nematode genera namely Trichodorus, Hemicycliophora, Xiphinema, Meilodogyne, Aphelenchoides, and Helicotylenchus. The parasitic nematode population-averaged 2.01 individuals/cm³.
