Larry where did you get the info for the Rose & Flower? The label I'm looking at for the "All in one Rose & Flower has this amount
Tebuconazole . . . . . . . . 1.06%
Imidacloprid . . . . . . . . . 0.11%
Clothianidin . . . . . . . . . 0.05%
The fungicide in the Rose & Flower is good for daylily rust although I don't know how well it works since it is such a low amount. Tebuconazole was actually listed in one of the AHS Daylily Journals as being effective.
The second insecticide (clothianldin) in the "Tree and Shrub" is in the same class as the Imidacloprid (they are both Neonicotinoids) so it does the same thing as the other. I am just assuming here that it works on caterpillars though where the Imidacloprid doesn't since on the "New" containers it lists caterpillars as a pest it kills.
The 12 month protection is what sold me on this and people who have used it says it last this long. I would rather put down something once a year and not every 6 weeks since I have enough to do already and that is just one less thing I have to worry about.
