Your soil is full of bacteria and worms which cause it to become rich and fertile. You couldn't have compost without bacteria. Do you really want to kill everything in your soil? Stop worrying about galls. I would do what Karl does except you don't need to dig up the rose and replant it. Galls are very slow. They wont come back for a long time if the do.

Galltrol-A or Gallex are generally what is recommended.

Thanks all.

hoovb,

Those were the two products that I found when researching bactericides. Unfortunately, their websites don't show where to purchase or their telephone numbers are disconnected. If you have more info on them, please let me know. Thanks for your input.

Regan's has a small Francis Meilland for me. And just to be safe, I think I will plant it in one of my large pots (24 gallons) and place the pot where the original was planted. I will be able to leave it in the pot for a couple of years.

As my friend and local rosarian said, this gall is not one of the 'slow' types. It grew to tennis ball size in a matter of less than 2 months.

Thanks again y'all,

andrea

Andrea, just in case you are interested in another option for dealing with Agrobacterium tumefaciens, I'm posting the link below, which is basically suggesting rotating a resistant species in the area where the galled plant was. According to the article at the link, "Growing a nonsusceptible crop, such as grass, for three years can essentially eliminate the bacteria from the soil".

Thanks Tessiess,

I've seen that option mentioned. Actually at that very site. That site suggested letting the soil 'rest' for a few years. I really like university sites. The problem is that it's a raised bed with only roses. It's probably the best option for the soil. But it wouldn't look great with 7 roses and a bunch of pansies. (a joke, of course)

The spot is the furthest back in my yard and is behind other roses The pot would therefore be 'hidden' from view.

Thanks so much for answering,

andrea
