I haven't even seen pruning spray stop suckering, maybe someone else has some trick, but it seems if it would stop the suckering it would damage the main plant. Is there root damage or condition problems that are contributing to the suckering?
So many roads to take, choices to make, and laughs to share!
We just have so many and we need to remove them before we sell them, so its a be labor intensive job cleaning all the stems.
I might get lucky and someone might have a trick, even a liquid wax.
I guess its a shot in the dark
Thanks for replying

So are you selling cut rose stems and you want them clean of their natural emerging leaves? How do you strip the stems of thorns? Wouldn't that also take care of the budding leaves?
And no, there isn't a spray.
No, there is no such product. Wax won't work as many commercial rose plants are waxed to reduce transpiration until they are sold and planted. The only way to prevent growth buds on rose stems/canes from having the ability to break into growth is to physically remove or destroy them. It sounds as though you are selling cut flowers and don't want them to be able to be propagated. Cut flowers generally don't last long enough for buds on their stems to break into growth. Physically removing or destroying them can be unsightly as well as labor intensive and it WILL produce wounds which can easily allow bacteria entry into the stems and reduce vase life.
