The disease, which affects banana and plantain, causes stunted growth, yellowing leaves, poor fruiting and, in severe cases, plant death.

Dr Lakpo Koku Agboyi, Senior Scientist in Invasive Species Management at CABI, said although BBTD had not been detected in Ghana, the country remained at high risk due to its presence in neighbouring countries such as Benin and Nigeria.

He told the Ghana News Agency at a stakeholder workshop in Accra that banana and plantain were staple foods, and any outbreak would have serious implications for food security and farmer livelihoods.

CABI is an international, intergovernmental, not-for-profit organisation that applies scientific expertise to address challenges in agriculture and the environment.

Dr Agboyi said the disease was spread by the banana aphid and through infected planting materials.
“Since most banana and plantain farmers source planting materials from their neighbours, there is a high risk of farmer-aided spread of the BBTD when it is introduced into the country,” he said.

A study by CABI found that many farmers had limited knowledge of the disease and its vector, and recommended sustained public education to support early detection, reporting and rapid response.

Over the past five years, CABI has supported surveillance and laboratory testing in collaboration with the Plant Protection and Regulatory Services Directorate and the Biotechnology and Nuclear Agriculture Research Institute.

Samples collected nationwide have so far confirmed the absence of the disease.

Professor Ken Okwae Fening, Associate Professor of Agricultural Entomology at the University of Ghana, said prevention remained the most cost-effective approach, as control after introduction would be difficult and expensive.

He advised farmers to avoid moving planting materials from unknown sources and to report unusual symptoms to agricultural extension officers.

Participants called for strengthened collaboration among government agencies, researchers, development partners and farming communities to enhance prevention efforts.
They emphasised the need for effective border inspections, increased awareness, early reporting and coordinated action to safeguard banana and plantain production.
