How It Works

Mode of Action (IRAC 21A): Inhibits mitochondrial electron transport in mites → disrupts energy production → rapid mortality.
Ovicidal + contact/ingestion: Direct action on eggs plus strong effect on nymphs and adults through both contact and ingestion.

Application Guidance

Timing: Spray at early infestation (egg/young nymph stages). Ensure thorough coverage, especially leaf undersides.
Water & nozzle: Use clean water; maintain recommended spray volume; use hollow cone or flat fan nozzles.
Resistance management: Do not use consecutive applications from IRAC Group 21A. Alternate with other modes of action.
