SWEET GUM BALLS--REMOVALNo chemical control is currently labeled in Illinois for preventing the formation of sweet gum balls. No control is available to cause the balls to abort at a young age.
The only control to prevent sweet gum balls from forming is a chain saw used at ground level.
Some research has shown that NAA (Naphthalene Acetic Acid) will cause some abortion. However, the compound is costly and hard to apply, and as stated, not registered for use in Illinois.
