Cassava pests and crop traits varied across Sierra Leone's regions
WHAT THE EVIDENCE SAYS
A January 2022 survey measured morphology, pests and cassava mosaic symptoms on 276 farms, sampling 30 plants per farm. Whitefly and grasshopper counts varied geographically, and disease-severity patterns differed by farm size.
WHY IT MATTERS / OUR READ
Local planting-material networks and landscape context matter more than assuming a nationally uniform pest or cultivar profile.
CAVEATS / UNCERTAINTY
Single seasonal snapshot; symptoms and farm associations cannot prove infection routes or a protective leaf trait.
