Aphids are a common early-season pest in maize, colonising young leaves and the developing whorl, where they feed on sap and can transmit viral diseases. Because infestations often build up quickly on tender growth, seed treatments that protect the plant systemically from germination onward are the most reliable way to keep populations in check before they establish. Here are three proven solutions.
1. Thiamethoxam 12.6% + Lambda-cyhalothrin 9.5% ZC
This combination pairs a systemic neonicotinoid (Thiamethoxam) with a fast-acting pyrethroid (Lambda-cyhalothrin) in a zeon capsule suspension formulation, giving both systemic uptake and quick knockdown. It's specifically registered for aphid, shoot fly, and stem borer together in maize.

2. Thiamethoxam 30% FS
This flowable seed treatment formulation of Thiamethoxam is rapidly taken up by the germinating plant and distributed to all its parts, including pollen, deterring feeding by early-season sucking pests including aphids. It's one of the most widely used seed treatments for maize, with dosing specifically calibrated for aphid control at sowing.

3. Thiamethoxam 70% WS
This high-concentration water-soluble powder formulation of Thiamethoxam is used as a seed dresser at the time of sowing. Being a stronger form than the 30% FS version, it works at a very low dose while still giving systemic protection against aphids and shoot fly in maize from the earliest seedling stage.
