The product I use JoAnn, is a liquid, and comes in one of those "hose end sprayer" bottles. I believe it is meant mostly for grubs in the lawn. I do use the Tree and Shrub ( has some fertilizer ,also)with Merit for control of Emerald ash borer. It's granular, and you sprinkle it on the soil, and water it in. Bayer makes several "controls" containing Merit, and not all are available everywhere, due to different state's regulations. As I said, to me at least, the best thing is a good visual inspection of the leaves, once a week ,or so, starting early in the season. The borer damage is easy to spot, and if you catch him early, still small, and high op on the fan, it's just "squeeze, POP!, no more borer! Arlyn
