My Climbing New Year Roses look bad

heidiho(St. Martinville, La. Zn.8)April 14, 2012

Don't know what happened to my Climbing New Year Rose this year. Last month it looked liked something was chewing up the leaves so I sprayed with Malathion and now I have a few sad looking roses but still not much leaves and the buds look eaten up before they bloom. Don't know how to post photo of these bad roses; sorry

Thanks for any advice you can give.

Have a nice day.

Are the buds gone or just have holes in them? Deer will eat rose buds and leaves. Earwigs and rose slugs will put holes in buds.

No deer around here.
I thought the Malathion would have taken care of any bugs. The buds are not gone but they do have holes and blackish looking.
Thanks

You really shouldn't apply any kind of pesticide without knowing what the pest is. Malathion is a broad spectrum contact pesticide that has no residual effect. This means that the product can't control anything that doesn't actually come into direct contact with it while it is still wet.

It's a cholinesterase inhibitor, by the way. Should be used only with extreme caution.
