Can Archer IGR be used on ornamental potted plants such as Orchids and Tropicals for mealybugs?

Answer:

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.
