When do I apply Merit 0.5 G for grubs in turfgrass in southwestern Michigan?

Answer:

Since Merit Insecticide Granules is a systemic insecticide, you want to apply it several weeks before egg match of the target pest. Usually this application needs to be made in late Spring, usually sometime between May and late June. We recommend contacting your local Cooperative Extension for the best recommendation on application timing for your target pest in your area.
