Effective management of invasions by Fallopia japonica are currently limited to repeated annual herbicide applications and research efforts are needed to determine integrated cost-effective treatments that result in greater management success. We evaluated several different herbicides for F. japonica control in the greenhouse and under field conditions and coupled chemical control with restoration activities at an invaded site. Results suggest that: 1) glyphosate applied at 4.21 kg ae/ha is the most cost effective treatment option, 2) the standard rate for F. japonica control with aminocyclopyrachlor is approximately equivalent to the 0.56 kg ai/ha, 3) restoration with grasses can be coupled with targeted chemical control.
