Hi there.
Narrow leaf cottonwood, Populus angustifolia, is know to produce heavy suckers. Keep in mind, that all of these suckers are connected to the "mother tree," as this is a major way of spreading. So, if you try to add a chemical to kill off a sucker, it could affect the mother tree. There is one product you can try, it is called "SuckerStopper."

It is not cheap, and requires multiple applications, but it may be worth a try. So, to answer you question, it will be difficult to control the suckers.
Good luck.
