A team of CABI and Plant Protection and Regulatory Services Directorate (PPRSD) scientists have shared their expertise on invasive species and development communications and extension to publish a new CABI Study Brief looking at the outcomes and lessons learnt from the implementation of a fall armyworm management plan in Ghana.

The invasive fall armyworm (Spodoptera frugiperda) was confirmed present in Ghana in 2016 and in 2018 reports suggest that the pest had caused losses of around US$177 million to the country’s annual maize crop – significantly impacting upon the livelihoods of smallholder farmers.

In response to the fall armyworm outbreak, CABI – through the Action on Invasives programme – launched a range of activities in Ghana in 2017 which included supporting the development of a national fall armyworm management plan together with the PPRSD of the Ministry of Food and Agriculture (MOFA), and other stakeholders.

The CABI Study Brief, ‘Implementation of fall armyworm management plan in Ghana: outcomes and lessons’, outlines how stakeholder collaboration at various levels led to increased public awareness of fall armyworm and management practices, research into low-risk management options, and contribution to policy and practice on how threats from invasive species could be managed more effectively in future.

CABI’s contribution included undertaking studies that provided evidence on the distribution and impact of fall armyworm in Africa, reviewing current research and development of control methods as well as a series of recommendations for the sustainable management of the crop pest.

Dr Monica Kansiime, one of the authors of the study brief, said, “Overall, the review of the implementation of the national fall armyworm management plan pointed to positive outcomes, and to specific areas of the plan that were successfully executed.

“In particular, successes were recorded in quickly reaching a wide audience of farmers and extension workers with knowledge on fall armyworm identification and management options; fall armyworm surveillance that covered the whole country, and collaborative research on best practice solutions including exploration for natural enemies, and evaluation of low risk fall armyworm control measures.”

The scientists add that the research results also helped shape policy and practice on the control of the fall armyworm with the Ghana Government choosing to promote biorationals. Furthermore, multi-stakeholder engagements also contributed to shaping the invasives policy that culminated in the development of a National Invasive Species Strategy and Action Plan (NISSAP).

Ebenezer Aboagye, Head, Crop Pests and Diseases Management Division at PPRSD, said, “The extensive sensitization and education of technical staff, farmers and the general public on early detection of the signs and symptoms of fall armyworm and early management was very effective in minimising the impact of the pest. The Plant Health Clinic sessions provided another opportunity for building smallholder farmer capacity for managing FAW in a sustainable manner.

“The three-tier monitoring (national, regional and district teams) approach adopted also provided regular feedback on fall armyworm situation that enabled quick review of management strategies such as the shift from the use of synthetic insecticides to biorational insecticides (botanicals and microbial pesticides) and biological control agents.”

Mr Aboagye added that the strengthening of the Fall Armyworm Monitoring and Early Warning System (FAMEWS) generate detailed and dependable knowledge on migration patterns of fall armyworm in the context of agro-ecologies and cropping systems. He said this approach can serve as a model for managing future incursion by invasive pests.
