14 July 2025, New Delhi: The Indian Agricultural Research Institute (IARI), Pusa, has issued a warning to maize-growing farmers across India about a rising infestation of the Fall Armyworm (FAW), a destructive pest known to cause significant damage to maize crops. According to IARI experts, early signs such as wilting plants and holes in the leaves indicate the presence of this invasive pest, which can rapidly spread and devastate entire fields if not managed promptly.
Identifying the Pest
Fall Armyworm (Spodoptera frugiperda) is a highly invasive pest that feeds on maize leaves, stems, and even cobs. It bores into plant tissue, hollowing out the stems and causing irreversible damage. The pest can move quickly from one field to another, making early detection and rapid response critical to prevent large-scale crop loss.
IARI’s Recommended Control Measure
To tackle this threat effectively, IARI has recommended the use of Chlorantraniliprole, a potent insecticide proven to control Fall Armyworm infestations. Farmers are advised to mix 70–80 milliliters of Chlorantraniliprole in 200 liters of water and spray it evenly per acre of land. The spray should thoroughly cover both the upper and lower surfaces of maize leaves to ensure maximum impact on larvae hiding within the foliage.
Urgency of Action
Experts at IARI emphasize that Fall Armyworm spreads quickly, especially in warm and humid conditions. Therefore, farmers should act immediately at the first sign of infestation. Timely spraying can significantly limit the spread and protect yields.
Moreover, neighboring farms are also at risk due to the pest’s migratory behavior. Regular field monitoring and coordination among local farmers are essential. If signs of the pest are observed, immediate spraying with Chlorantraniliprole is strongly advised.
