    You poor thing you really are going through it aren't you? It is enough to make you want to give up and throw in the towel.

    I am a Consulting Rosarian and I can help! I also take care of 30 rose gardens and over the years I've seen a lot off stuff! But I've never seen that leaf notcher before! I will say that beetles and weevils in general are very hard to kill. Mostly I kill what I see because the alternative is heavy duty insecticide. Don't let anyone talk you into using milky spore. It works on Japanese beetles but not much else. So for *now* I suggest doing nothing about the notchers other than picking them off when you see them.

    It would help to know what kind of roses you have and how many?

    Blackspot is something that you need to prevent. It is very difficult to get under control when you already have it. If you have modern roses then it is pretty much a given that you've got to spray them with with some chemical preventive. Rose Pride by Ortho is the ole standby BUT always wear eye protection when using it. Rose Pride can be combined with Dithane M-45 found at garden shops not at box stores. Using together will help you get a handle on the BS quicker.

    I was one of the first ones to find chili thrips. No one knew what they were! And they are sooo tiny!
    Conserve is a good product. It comes in a quart bottle and is thick and white. If what you bought is clear then you have the "lite" product which I have heard doesn't work as well...but use it.

    As with all insecticides it is a good idea to rotate to avoid the little biggars from building up a resistance.

    It will be helpful to know how many roses you are growing so I know what products to suggest. I wouldn't suggest the same product for 5 roses as 25 roses.

    Let me hear from you...

    Thanks so much Laura for your reply. I only have 7 roses at the moment. 2 double knockouts-1 tropicana 1- Fragrant cloud 1-Cinco de mayo 1- yabadabadoo and 1 J&P rose which I have no name for but it is a hybrid tea also. I use bayer advances disease control for BS.,Carbaryl for weevils (but doesn't work) and conserve naturalyte for chilli Thrips. For fertilization I use Rosetone and fish emoltion. You are right about me wanting to throw in the towel or trowel..lol but the rewards are hopefully greater than the trials. Thanks again Laura and GOD BLESS

    It sounds like you are doing the right things. I would alternate the conserve with ortho's orthene. Read the directions for application rates.
    The original Knock Out rose is a chili thrips magnet but I don't think the others are as bad.

    You are right about the knockout rose I firsst noticed it on that . I thought it was Chemical burn at first and stopped spraying for a while but things got worse. Is there anything I can do about the weevils? they are eating my roses alive.I really don't like bugs!!

    Greeting all,
    I don't know a thing about roses and I didn't know anything about chile thirps until about two weeks ago. I found out I had thirps on my... guess what... chiles... when I took sample leaves to my local extension office. I have over 70 varieties in containers and I noticed some leaf crinkling that I thought was a deficiency or burn. Nope, thirps! I sprayed once with Monterey Garden Insect Spray (spinosad) and I have not seen any since. I've got my fingers crossed!

    I know little about rose pests except I hate anything that kills my roses. The leaf notching, if it is a "cut out" type could be from the leaf-cutting bee. I never heard of this before Tom Maccubbin had an article on it a month or so ago.

    So I don't mind the bees, just hate the chilli thrips.
