Stalker is a broad-spectrum insecticide. It has low aqueous solubility and low volatility and based on its chemical properties, would not normally be expected to leach into groundwater. Stalker mode of action through disruption of oxidative phosphorylation in the mitochondria rather than to target neural receptors and absence of cross-resistance was anticipated to the generally used insecticides for vector control including pyrethroids. Stalker has broad-spectrum control over insects and controls whitefly (nymphs), aphids, and rice plant hoppers.
