I use Merit for my iris borer deterrent/poison.  I also use it on my 
roses. I was complaining the Merit was not stopping the Japanese 
beetle from attacking the blossoms. A friend who has a commercial 
greenhouse business told me that systemic will not go into the 
blossom. He is very knowledgable about insecticides, fungicides. I 
can verify, having incorporated the merit into the soil and well 
watered, that the blossoms were smorgasbord.
