I used to use Ortho Systemic Rose & Flower Care granules which worked very
well. Ever since Bayer restricted the Di-Syston ingredient for their
product Advanced Garden 2-in-1 Systemic Rose & Flower Care, I have not
had the same luck; aphids just seem to ignore the Bayer. Is anyone using
the Bayer successfully? I am in No. California.

Thanks!
