Rose growers. Do yellow roses get aphid's worse?

I have red, yellow and oranges roses all side by side. The yellow one keeps getting aphid. I use Garden safe insecticide soap...they keep coming back. What do you use?

Rose growers. Do yellow roses get aphid's worse?
Instead of using insecticides, I just spray all new growth and buds with a stiff jet of water from my hose. I do that about once a week and haven't had much of a problem. My aphids seem to prefer my climbing roses over my tea roses, but don't seem to have a color preference.



Also, spraying the roses rinses off fungus spores and the honeydew produced by the aphids. This can reduce other problems with disease and infestations.



You can also toss a banana peel into the mulch at the base of your roses. I'm not sure why this helps reduce aphids, but it does.
Reply:Aphids get into any color of rose, most to any flowering plant. You have to spray them with garden p[est control. Do it after you watered your roses. Aphids thrive underneath the soil, there are chalk-like sticks you can dig in through the soil- preventing the pest to grow. Soap water spray is also good, but i don't find it effective on aphids.
Reply:Some varieties always seem more prone to aphids, and yellow is more attractive to many insects than red or orange. Greenhouse sticky traps are all yellow. If you can find an insecticide that is described as `systemic`, use it. This would be a great improvement on soap.There are many `all-in-one` rose preparations available giving protection against aphids, mildew, rust, etc.
Reply:Visit your local Lowe's or Home Depot and look for a product made by Bayer.It is called Bayer Advanced Tree and Shrub Insect control concentrate.The active ingredient should read "imidacloprid".Follow the label directions and apply accordingly and your roses will be free of aphids.
