Doris, is it the 3-in-1 insect, disease, and mite control? That shouldn't have to be poured around the daylilies, you should be able to use as a foliar spray. I know they have some that has to be poured around the plants. Those types are meant for the roots to uptake the chemical from what I understand. I've used the Bayer Advance Tree and Shrub (granular form) and it works the same way as the liquid you pour. None of those work on spider mites though, you have to use a miticide. Since they are arachnids, 99% of insecticides will not kill them; if you have them Avid works great although we use an ovacide since Avid doesn't kill the eggs. But that's one reason they say spray 2-3 times that way you kill any new hatched mites. If it is the 3-in-1 insect, disease, and mite control then it should work for spider mites as well since it's listed. The only problem with that is you will end up spending more on the ones from Lowes/Home Depot because you have to add more to the water. The quart of the 3-in-1 concentrate only makes 12 gallons of spray so I would have to actually have 3 bottles on hand to make enough and that would be $45 right there and If I had to spray again then I would have to buy 2 more bottles and that would be $30. So I would spend $75 if not more for one season. I can get the Avid generic for around $95 and it will last me at least a few years. I can also get the generic Imidacloprid for around $35 and it will last even longer. Now in the 3-in-1 it has Tebuconazole which is good for rust. However, it is in such a low dose I'm not sure if it would really work well unless you spray every week. You wouldn't want to be spraying the insecticide in it that often. And with as many daylilies as you have the economical route would be the generic Avid. IMHO
Betty, the Bayer Advanced Complete insect Killer makes up to 80 gallons so that is a good amount and that's why I bought that one in the beginning.The reason I bought it to begin with was I had a lot of earwigs and they starting coming into the house so I started spraying the mulch around the house. Also we have leafhoppers really bad here as well so I used it for that too.
There is other stuff out there that is probably just as good if not better, but this is what I have found effective for me.
