Can I use Merit in a Waterboy water machine as a systemic for tropical plants with mealybugs?
Is Merit the most effective product for mealybugs?
Unfortunately we are not familiar with a Waterboy. Please contact the Waterboy manufacturer to see if wettable powder insecticides can be used in their device. Merit is indeed very effective for mealybugs.
