Herbicide Application


Understory Release Application

Understory release applications are conducted to control unwanted woody vegetation that is competing for site nutrients and moisture.  This operation is often performed in the first few years following a thinning as unwanted vegetation colonizes ground that is freshly exposed to sunlight. 

  • Applied May-October
  • Applied via skidder or tractor
  • Studies show financially viable if BA of competition exceeds 10 sq ft/ac
  • Can control waxy species that are uncontrollable via aerial applications
  • Can be applied under pine or hardwood canopies without damage to overstory

Understory Release Application

Logging  skidders modified with spray equipment are most commonly used in 
understory  release  applications.
