How is the suckering problem avoided in the case of rugosa stems for
standard roses?

It tends not to be so much of a problem with standards and any suckers that do appear are easily seen and easy to get
to - not like in a thicket of shrub roses. Hopefully you have this great vigorous head on the standard asserting apical
dominance - ie hogging all the auxins (growth hormones) and inhibiting growth of buds lower down.
