  3. Unravelling the diversity and distribution of the soybean rust fungus Phakopsora pachyrhizi in east Africa por Murithi, H.M.

    Publicado 2019
    “…The relatively poor yields can largely be attributed to abiotic factors (soil fertility, drought, poor nodulation) as well to as biotic ones (diseases and insect pests). Rust caused by the biotrophic fungus Phakopsora pachyrhizi is a major threat to soybean cultivation, as it can cause up to 80% yield loss. …”
