Does Merit Control Rose Chaffers?

Looking to spread in sandy soil over a large area to control rose chaffer hatch in June in Michigan.

Answer:

Merit 0.5 G Insecticide Granules is not labeled for rose chafers but it is labeled for a variety of other chafers. I have linked an article from the University of Minnesota, that states that the active ingredient (imidacloprid) is known to control the rose chafers though.
