Thanks, Michele. Yes, this information is very helpful. I had bought a half gallon of the Advanced Bayer Systemic 3 in 1 from Lowes before Christmas. I just read the information on the back again. It is supposed to kill aphids, thrips, and leaf miners among other insects. I did not realize that I have to pour the mixture on or around the plants. That is not practical here, too many dayliles. I had planned to spray the daylilies. I got a 4 gallon backpack sprayer for Christmas. Do you know if it will be just as effective if I spray the foliage real good with this systemic? If not, I need to get the generic Avid. I am not sure if we have spider mites or not but figure we probably do. I will see Bill Waldrop next Sunday at our daylily meeting. I can find out from him just when and how often he sprays the Avid. I want to have what we need on hand for when we need it. Once again, thank you.
