How much Merit 0.5 G granules do I apply per rose bush


The application rate of any insecticide is going to depend on the insect you are targeting.  With roses being sensitive to certain active ingredients and application methods, we highly recommend speaking with the manufacturer to determine the specific application rate of Merit Granules to treat your roses. You can reach Bayer at 800-331-2867.

Here are two options for alternative products that contain Imidacloprid (same active as Merit) Both are applied around the root zone and are used for basically the same treatments.

Bonide Systemic

Fertilome Tree and Shrub
