Plant-parasitic nematodes are tiny worms that live in soils and roots; in the case of banana plants, they spend most of their life cycle in root and corm tissues. Their proliferation mainly disrupts nutrient and water uptake, delays growth, and may cause the banana plants to topple over. Until recently, most methods for the control of banana nematodes relied on the use of chemical nematicides, many of which are gradually being banned in Europe. This guide reviews the main steps of alternative integrated plantparasitic nematode management in banana cropping systems in the French West Indies. This includes i) soil sanitation measures such as improved fallow to cleanse the soil of the burrowing nematode Radopholus similis, water isolation ditches to delay recontamination of fallows and already sanitized plots, along with the use of non-host plants including cash crops, pasture grasses, and legumes; ii) monitoring of soil sanitation before planting new banana crops; iii) use of healthy planting material, mainly tissue culture banana plants; iv) use of nematode tolerant banana varieties, and in the medium-term, nematode resistant varieties; and v) further integration of management strategies and the reintroduction of biodiversity to ensure sustainable control of nematodes.
