I had a nurseryman recommend Spinosad for control of thrips on roses.
Yes, you can use Captain Jacks Deadbug Brew Concentrate to control thrips on roses. Per the product label, you will use 2 oz. per gallon of water, (or 0.5 oz per quart, or 0.25 oz per pint) and spray to the point of runoff. Be sure to cover upper and lower leaf surfaces.
