Entomology and Plant Science Bureau
State Weed Commissioner

The State Weed Commissioner, as established by Iowa Statute, chapter 317, and administrative rules, chapter 58, resides in the Entomology and Plant Science Bureau.  The state weed commissioner assists county weed commissioners with legal questions and technical support.   Additionally, there are numerous exotic weeds at risk for introduction into Iowa, that would adversely impact Iowa’s agricultural and rural areas. When opportunities arise, the state weed commissioner works with USDA on bio-control programs.
