A risk-minimizing argument for traditional crop varietal diversity use to reduce pest and disease damage in agricultural ecosystem of Uganda por Mulumba, J.V., Nankya, R., Adokorach, Joyce, Kiwuka, C., Fadda, Carlo, Santis, P. de, Jarvis, Devra I.

“…This uniform resistance is met by the continuing evolution of new races of pests and pathogens that are able to overcome resistance genes introduced by modern breeding, creating the phenomenon of boom and bust cycles. One of the few assets available to small-scale farmers in developing countries to reduce pests and diseases damage is their local crop varietal diversity, together with the knowledge to manage and deploy this diversity appropriately. …”
