Tokuthion is a Bayer product, containing the active constituent prothiofos which is a 1B insecticide. Tokuthion was previously registered for control of longtailed mealybug (Pseudococcus longispinus) on grapevines (WA, NT, SA and VIC only). The wine grape registration has been withdrawn but the table grape registration still stands.
