Systemically will it reach the rose buds? Those suckers feast on the flowering parts.
The Dominion 2L can be used as a systemic application to roses and other plants for thrips and it would do a great job. If you have a heavy population of them though, you may find that you need to do a foliar application to the buds while the systemic makes its way through the plant to eliminate them and protect them for the rest of the season. Products like Talstar P are often used in this instance to spray where they are currently damaging the plants and provide residual control for a month or so on the surface. If you use the Dominion, you would apply at the rate of 0.2-0.4 oz per foot of shrub height in roughly 1-2 gallons of water based on your rose bush size.
