Pest/disease control

Production of maize, Zea mays L. (Poaceae), in sub-Saharan Africa is threatened by a new invasive pest, fall armyworm (FAW), Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae). To mitigate this threat, push–pull companion cropping, a system originally developed for management of lepidopteran stemborers, may be used to control FAW.

Agricultural production systemSoil management

Soil degradation is a major underlying cause of poverty and malnutrition in smallholder agrarian communities across the globe. Legume diversification, through polyculture or intercropping, is a strategy that increases yields and income while improving family nutrition.

Our study evaluates field performance and farmer opinions of this new version in comparison with the earlier version, climatesmart PPT, and farmers’ own practices of growing maize in controlling stemborers, FAW, and striga weeds.
