Actellic Gold Dust is a broad-spectrum grain storage insecticide specially formulated to protect stored maize against the most destructive storage pests in Kenya, including the Larger Grain Borer (LGB), grain weevils, and flour beetles. It is applied directly to harvested grain to prevent post-harvest losses and maintain grain quality during storage.
The product combines two active ingredients with different modes of action, providing rapid knock-down of existing infestations and long-term residual protection, even under tropical and humid storage conditions. Actellic Gold Dust is ideal for smallholder farmers, traders, and commercial grain stores seeking reliable maize protection.
