Hello,

From all three images, I identified this rose shrub with my plant id app as China Rose (Rosa chinensis) - Other Common Name: Butterfly Rose
If you know the name and my identification is incorrect, please let me know. Thank you!

Also, can you please send me some more clear and close up images of these rose shrubs - Please focus on disease parts of the plant

As soon as I get these new images, I will get back to you!

Thank you!!

Thank you for your help! Are these pictures better. If not I am happy to retake some pictures tomorrow. Let me know what is the best area that you need to see.  I feel there are lots of dead branches mixed in with some healthy limbs. I have approximately 14 rose bushes and some have more dead branches than others, but it seems to me that the roses with dead branches seems to be spreading from one plant to the next in a linear fashion. 

Hello,

It’s unfortunate that your rose bushes are experiencing issues. Based on the symptoms you’ve described, it’s quite likely that you’re dealing with Rose Rosette Disease (RRD). Let me provide some information about it:

Rose Rosette Disease (RRD):

RRD is caused by a virus and primarily affects roses (Rosa species and hybrids).

Symptoms include:

Elongated shoots: Some stems may appear unusually long and have red or yellow coloration.

Witches’ broom or rosette: This is a brush-like cluster of shoots originating from the same point. Leaves within the witches’ broom may be stunted, distorted, and pigmented red or yellow.

Excessive thorniness: Infected stems may develop more prickles (thorns).

Discolored and distorted growth: Leaves damaged by RRD remain discolored and distorted.

Reduced winter hardiness: Infected roses are weaker and more susceptible to cold damage.

Increased susceptibility to other diseases.

Unfortunately, there is no cure for RRD, and symptomatic roses should be removed to prevent further spread. More information at this link:

Other Possibilities:

While RRD is a likely culprit, it’s essential to rule out other factors:

Rose Blackspot: A fungal disease that causes dark, circular lesions with feathery edges on leaves and raised purple spots on young canes. However, this doesn’t explain the linear spread you’ve observed. More information at this link:

Rx for Roses: Gardeners reporting cases of rosette virus, blackspot (k-state.edu)

Other pests or diseases: Consider checking for aphids, spider mites, or other issues that could cause branch dieback.

BEFORE YOU REMOVE THE PLANTS - To be certain, I highly recommend you consult with a the MSU Plant & Pest Diagnostics Lab. I recommend you send all your images by e-mail to the MSU Plant & Pest Diagnostics Lab for a confirm and precise identification. The experts there can also provide you with the best treatment options. Their email is <personal data hidden> - Please include your name – The lab will let you know if they need a sample sent. FYI – The lab may also ask for additional images too.

Their website is at this link:

If the lab wants you to submit a sample, this link will explain the details on submitting a sample to MSU Plant & Pest Diagnostics Lab:

Remember to clean your pruning tools thoroughly between plants to prevent disease transmission. If it is indeed RRD, removing affected plants promptly is crucial to prevent further spread. 

I hope this helps!
