New cover crop termination publication available

Evaluate your cover crop termination strategy.

April 3, 2018 - Author: Erin Hill, Michigan State University Extension, Department of Plant, Soil and Microbial Sciences

As the growing season approaches, cover crop termination is one of the first field activities on the horizon. Complete termination of a cover crop is essential to prevent poor seed placement of the cash crop, allelopathy, potential insect issues such as seed corn maggot, and crop competition. Failed or incomplete termination often deters future cover crop use.

To increase the rate of success, the Michigan State University Extension cover crops team has released “Cover Crop Termination,” a new publication co-authored by weed extension specialist Christy Sprague and weed science diagnostician Erin Hill. Cover crop termination methods discussed include winter kill, mechanical methods and herbicide options.

Table 1 of this document details the effectiveness of these methods for specific cover crop species, including suggested herbicide rates. This table also lists the rotation intervals required for subsequent cash crops following the listed herbicide applications.
