Liquid Imidacloprid spray for borers

I used Bayer Advanced Garden Tree and Shrub Insect Control. It comes in a concentrated liquid form and costs about 24.00 in garden supply stores. It doesn't even mention borers or even grubs.' But it is imidacloprid. I diluted it, added some 'sticker' and got myself a 20.00 pressure sprayer. I used about half the 32 fl oz bottle for about 800 rhizomes. I sprayed in April when the fans were approx 4" high...all over the fan and around the rhizome. The iris didn't mind a bit.
Actually, the product is not my discovery. I read about someone elses success with this product in an AIS journal article last year. The results using the liquid spray vs the granules are just too dramatic to ignore.
