I agree with Casshigh on the Bayer 3in1, I like all the Bayer products.
I use other things for rust and insects since we have soooo many daylilies, we buy the larger professional products. But when I had less to tend to I'd use the Bayer advanced complete insect killer (soil and turf) which is good for foliage insects and soil insects and the tree and Shrub granules and love them.
For the past month we've had lots and lots of ladybug larvae everywhere so I try not to spray anything since they can do a better job than me at getting the insects, but since we have very mild winters (usually) we will have outbreaks of aphids and Spidermites when there are no beneficial insects around so we have to spray.
