Concerted cross-sectoral action is needed to save Africa’s most important staple – maize. Besides prolific insect vectors, seed too poses a problem, with continued production, distribution and cultivation of commercial MLN-infected seed. Other than a recent CIMMYT study on Kenya, there is little information on MLN incidence, distribution, severity and impact. More studies like this would help to quantify the magnitude of the disease. Still, the conference made important recommendations on joint action and regional protocols.
