Relating soil herbicide residue levels to sugar beet stand and growth reduction
Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.Abstract One common recommendation given to farmers who suspect herbicide carryover to sugar beet (Beta vulgaris L.) is to conduct laboratory tests to assess herbicide residue levels in the soil. While this is often a good practice, there are currently no guidelines on how these laboratory test results relate to sugar beet damage or yield loss ...
