Crop rotations and their resistance to plant-parasitic nematodes Plant-parasitic nematodes are a major constraint to banana production. An important strategy for management is the use of non-host rotation crops that limit nematode feeding and reproduction. This selection tool provides recommendations for Queensland horticultural industries on the most suitable rotation crop to manage a specific plant-parasitic…
