Farmers Face a New Invader: How Ghana’s Maize Growers Fight the Fall Armyworm

Maize farmers in Ghana are battling a relentless pest that threatens their income and food security. The insect, known as the fall armyworm, has spread across the country, damaging crops and making it hard for farmers to keep up. Researchers studied how these growers view the problem and what tactics they use to protect their fields. The study found that most farmers are aware of the danger the armyworm poses, but they differ in how seriously they take it. Some believe that natural predators and cultural practices can keep the pest at bay, while others rely on chemical pesticides. The choice of method depends on several factors. One key factor is access to information. Farmers who receive training from extension workers or community groups are more likely to try integrated pest management, combining crop rotation, natural enemies and selective insecticides. Those without such support often default to buying ready‑made sprays from markets.

Cost is another major influence. Inexpensive or locally available solutions appeal to smallholders with tight budgets, even if they are less effective in the long run. Conversely, farmers who can afford higher‑priced chemicals or have cooperative buying power are more willing to invest in stronger controls. Experience also shapes decisions. Farmers who have seen the fall armyworm devastate crops in previous seasons tend to adopt more aggressive measures. Yet some still hesitate, fearing chemical residues or market restrictions on pesticide use. The research highlights the need for targeted education and affordable tools. By strengthening extension services, improving access to low‑cost biocontrol options, and fostering farmer cooperatives, Ghana can help growers make smarter choices that protect both their yields and the environment.
