Provision of pest alerts is associated with better farm performance in Africa.
Article in Pest management science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCrop pests cause substantial crop yield and economic losses, food insecurity, and negative impacts on human health and environment globally. Timely provision of pest risk alerts - that is, the optimum time to intervene against key pests before invasion or establishment - to smallholder farmers on pest management could improve farm performance. However, there is little quantitative evidence testing this hypothesis.
resultsTo address this gap, we use primary survey data from over 4000 smallholder farmers across four African countries: Ghana, Kenya, Malawi, and Zambia. Our results suggest that providing pest alerts to smallholder farmers is associated with a higher probability of adopting integrated pest management (IPM) practices by 8-32 percentage points, as well as an increase in crop yield and income by 18-26%.
conclusionImproving timely access to information on pest risks and management could have substantial benefits on farm productivity and income in Africa. Our findings provide a practical pathway on how pest-induced crop losses could be minimized by addressing informational barriers. © 2025 The Author(s).
