BACKGROUND
Microscopic unsegmented worm; migratory endoparasite of plants. Strong sexual dimorphism; reproduction both by amphimixis and self-fertilization.
UNASSIGNED
Over 250 different plant species, including citrus, black pepper and banana (main host plant).
METHODS
Purple to black lesions and extensive cavities in plant roots, leading to reduced uptake of water and nutrients. In banana, this may result in poor vegetative growth, reduced bunch weight and toppling of plants.
RESULTS
Nematicides, alternative cropping systems, nematode-free planting material, some resistant cultivars.
UNASSIGNED
Major problem in banana plantations in tropical regions worldwide.
