What Insecticide Spray To Use On Viburnum

Question From: Utica, Michigan, United States
Q: Need to know the name of oil spray that was in your column about 2 weeks ago. We have all seasons spry oil. Will it work on the viburnum?

A: I used AzaMax, available at Hydro stores or online at Amazon.com. I will need to spray again when the beetles hatch. I check my shrub daily. It's too late to use horticulture oil. It must be applied in spring - mid April. Check out the Cornell website for more information. Best And Happy Yardening, Nancy
