I have 150 roses with rose midge. My yard is fifth of an acre. The recommended treatment is Merit granules. Can I spread it around the drip line and at what rate? The H-Yield (.22) recommends 1/4 cup per plant.
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.
