Hundreds of eggs laid by each female fall armyworm hatch into larvae that chew through rice plants, leaving devastated fields behind.

Chemical blitzes by desperate farmers combat these pests but create a toxic cycle of pesticide resistance and environmental harm.

Staggered planting times, deep soil turning, and field cleanup are being deployed as front-line defenses against fall armyworm populations.
