EPA registration data for Reg. 91234-164 →
Acronyx 4 F is an insecticide containing 40.7% Imidacloprid, used for controlling various pests including aphids, leafhoppers, whiteflies, and thrips in various crops such as cotton, peanuts, potatoes, and various vegetables/fruits. It is used via soil treatment (in-furrow spray or drip irrigation) or foliar applications (broadcast or directed spray). The product is highly systemic, moving through the plant's xylem to protect new growth. Key handling notes include: it is toxic to bees and other pollinators; do not apply during bloom or when pollinators are active. Applicators must wear long-sleeved shirts, long pants, chemical-resistant gloves (nitrile $\ge$ 14 mils), barrier laminate ($\ge$ 14 mils), polyvinyl chloride (PVC) ($\ge$ 14 mils or $\ge$ 14 mils), and shoes/socks. Avoid application near water or in areas with shallow water tables to prevent groundwater contamination. Always follow specific crop-label instructions for rates and timing.
