Pratylenchidae

Pratylenchidae is a family of nematodes, small, unsegmented roundworms, belonging to the order Tylenchida. They are parasitic, feeding on plant roots and causing significant damage to crops. The family includes several genera, with Pratylenchus being the most well-known. Pratylenchus penetrates the root surface, feeding on the cortex and endodermis, leading to stunting, yellowing, and wilting of plants. Symptoms vary depending on the host plant and the species of Pratylenchus. Control measures include crop rotation, use of resistant varieties, and chemical fumigants. Pratylenchidae nematodes are widely distributed in agricultural soils, particularly in temperate regions. They are of economic importance due to their ability to reduce crop yields and quality. Research is ongoing to develop more effective management strategies for these parasitic nematodes.
