What does this research mean for the field?

Emamectin benzoate provides highly effective suppression of fall armyworm in maize across Kenya and Ghana, and specific local maize varieties such as Omankwa, Pioneer, SC 73 Tumbo, and WH508 exhibit significant natural resistance to the pest. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This research aims to evaluate integrated management strategies against fall armyworm in maize in Kenya and Ghana. It focuses on identifying effective and cost-efficient options for smallholder farmers.

Randomized trial evaluates pest management strategies in maize, suggesting effective options for smallholder farmers.

Key Points

This research aims to evaluate integrated management strategies against fall armyworm in maize in Kenya and Ghana. It focuses on identifying effective and cost-efficient options for smallholder farmers.
Conducted on-farm trials in Kenya at Bungoma and Embu, and in Ghana at Kpong and Pampaso.
Compared six treatments against untreated control, including emamectin benzoate and Bacillus thuringiensis, with weekly leaf damage and larval assessments.
Screened local maize varieties for natural resistance to fall armyworm.
Emamectin benzoate consistently resulted in lower leaf damage levels (1.06–1.35) compared to the control (3.21–4.60) in Ghana.
Bt sand granules were effective in Ghana (1.20–1.29) but less effective in Kenya (3.98–6.97).
Local maize variety Omankwa showed lower leaf damage levels (1.91–2.73) than the Lake hybrid (2.78–3.93) in Ghana.
