摘要: AbstractPotato cyst nematodes are a major threat to potato production worldwide. In 2006, the isolation of golden nematode, Globodera rostochiensis, in Quebec, Canada, led establishment quarantine area and initiation research programme for sustainable management this regulated pest. study, field efficacy crop rotations soil amendments was assessed microplots their potential reduce populations G. rostochiensis area. Crop rotation with resistant cultivar very effective decreasing population density soil. A single year carrying H1 resistance gene reduced nematode by 62–95%. After 3 consecutive years cropping potato, number viable eggs zero several microplots, overall reduction around 95%. Natural decline cultivation non-host such as corn 30% per year. Trap cropp...
