Is Hi-Yield Bug Blaster Bifenthrin safe for roses?
Hi-Yield Bug Blaster Bifenthrin 2.4 RTS is labeled to be used on ornamental plants (and roses specifically) and when used as directed should not damage them. Having said that, roses can be sensitive so we always recommend you spray one plant before spraying all of them and that you avoid spraying the actual flowers on any ornamental plant.
