Uganda faces threat from corn disease

Uganda's food security is threatened by the spread of a destructive corn disease, first reported in Kenya and Tanzania.

The Ugandan Ministry of Agriculture warned that Maize Lethal Necrosis (MLN) had been reported in some districts in eastern Uganda, particularly Busia and Tororo.

The disease can cause up to 100% crop loss. It is suspected to be spread by beetles, thrips and leaf hoppers.

Uganda scientists are working in collaboration with International Maize and Wheat Improvement Centre [CIMMYT] to find solutions against the disease.

CIMMYT is also working with the Kenya Agricultural Research Institute (Kari) to develop corn varieties that are resistant to the disease.

MLN attacks all corn varieties.

Farmers have been advised to practise crop rotation and avoid planting corn for at least a year. They are also told not to replant seeds from the previous harvest.

Other measures recommended include weed control, proper use of fertiliser and high quality seeds to boost production.
