Smooth scouringrush control with fallow-applied herbicides in a winter wheat/spring wheat/fallow rotation

摘要

In 2015. we repeated a 2014 field trial evaluating herbicide control of smooth scouringrush in a no-till winter wheat/spring wheat/fallow cropping system. Smooth scouringrush is a deep-rooted native rhizomatous perennial that is becoming more prevalent in no-till/direct-seed cropping systems in eastern Washington. Current herbicide strategies for in-crop and fallow weed management have failed to reduce or control scouringrush and patches are persisting.
