Sue from Ocala, Fl writes,
Can Archer IGR be used on ornamental potted plants such as Orchids and Tropicals for mealybugs?
Archer IGR is not labeled for mealybugs. When treating for mealy bugs, you could apply TriStar 8.5 SL, and you will use 7.5 ml (0.25oz, 1.5 tsp) per 3 gallons of water for effective control. The Tristar bottle will measure as low as 5 ml in the built-in measuring reservoir. It is suggested that you mix a surfactant with the TriStar when treating for mealybugs for better control. You can use the Non-Ionic surfactant we carry at the rate of 1-2 teaspoons per gallon of water. Do not make more than 4 applications per year. Do not reapply more than once every 7 days. To determine if application is necessary, monitor pest densities.
