I didn't know Bayer 3 in 1 would help. I use it every spring to keep thrips and spider mites at bay. Now I'll apply it in the fall as well. I have an extensive case of rust right now that started with Lillian's Jinger Bred. Luckily, our winters have always been cold enough to kill the rust. While I cut back the first ones to break out with rust to try to stop the spread, it is so pervasive now I will just wait until the first frost to cut back the foliage like usual. I don't have time to look at the foliage closely this time of year, so it doesn't bother me. In the past when I severely cut back the foliage on affected plants it severely reduced bud counts the following year.
