Plant-Parasitic Nematodes Associated with Potato Production and Current Management Trends: A Systematic Review (2016–2025)

Potato is the third most important food crop in the world after maize and rice. Its importance stems from its contribution to food security in most parts of the world. Although the crop is widely cultivated globally, it faces numerous biotic and abiotic challenges, among which plant-parasitic nematodes pose a significant threat. The objective of the study is to map the nematode species affecting potato crops while drawing links with their pervasiveness and outlining effective control strategies. The article selection process followed the PRISMA guidelines. A total of 41 articles were selected for the review from an initial 944 records retrieved from the Web of Science, Scopus, CAB Abstract, and reference list based on their relevance to the study criteria. The findings indicate that G. pallida, G. rostochiensis, M. incognita and M. javanica were the most reported nematodes globally. Chemical and biological control remain the most widely used management strategies, while incorporating resistant cultivars, abiotic inducers, organic fertilizers, and crop rotation offers greater potential to enhance the sustainability and resilience of farming systems. A significant global research gap persists in nematode surveillance and diagnostic surveys of potato-growing regions.
