Larry I use it and love it. Last year there was only one bed I used it in and it was my show bed and it was the only bed without thrip damage. It is the only thing (besides the other Bayer products) that seems to control the thrips here. Another good thing to use for thrips is Horticultural oil (some use Murphy's oil) and it helps but that would require it to be timed right. I forget who uses it and as soon as the buds start appearing they spray. The year I used the oil it helped tremendously but it does require repeat sprays (at least here)
Back to the Bayer..... I used it around every single daylily I have this year and how I put it down is I imagine what size pot the plant will fit into and then go by the label for container sizes. If you add a little too much it's not really going hurt. Most of my good sized clumps got the amount for the 5 gallon container (I think I did 3 Tbs instead of 2 1/2). If they seemed really big I just added an extra Tbs. It will seem like it isn't enough when sprinkled around the plant but once it is watered in it is plenty.
There are actually 2 different products in this line now.

One has only the Imidacloprid and the other has Imidacloprid and Clothianidin (this one says dual-action on bottle). Other than the added ingredient and lesser Imidacloprid I haven't really looked to see if the labels say it kills anything different than just the one ingredient. I have found that the 2 containers may be mixed together on the shelf at the store. I think I found the difference, the one with 2 ingredients says it •Kills destructive Caterpillars – including Gypsy Moths and Tent Caterpillars.
Besides Bill Waldrop using it I know Larry Grace does also. I have seen it mentioned on the email robin being used by some of them.
