In recent years, fall armyworm (FAW), Spodoptera frugiperda, has emerged as one of the most serious invasive species in many countries across Africa, Asia and Oceania. The pest is causing extensive damage to maize production and the intensification of pesticide use. In this paper, we examined the effectiveness of three mass-extension channels (plant health rallies, radio drama and SMS) in enhancing farmers' knowledge and management of FAW and in increasing maize productivity.
