Stop Armyworm Damage with Napier Grass in Maize

Estimated Reading Time: 15 minutes

TL;DR: Intercropping maize with Napier grass can significantly reduce fall armyworm infestations. Napier grass acts as a trap crop, reducing pest populations by 60%, boosting maize yields, and increasing farm income by 45% per acre, according to KALRO 2025 trials in Kenya.

Background & Context

In Kenya and across East Africa, fall armyworm infestations are crippling maize yields. Recent field trials show intercropping with Napier grass reduces these pest populations by 60% through natural pest suppression. This approach promises to boost yields and income while promoting sustainable farming practices.
