Cell Division Inhibitor Herbicides

This issue of Crop Insights discusses cell division inhibitor herbicides. Preemergence acid amide grass herbicides are the most notable members of this group. Cell division herbicides:

• Interfere with cell division and cell enlargement.
• Are absorbed by roots and shoots.
• Inhibit shoots, cause grasses to leaf-out below the soil surface or fail to unfurl, and cause crinkled leaves and/or a shortened mid-vein in broadleaves.
