Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence
Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Cover Crop Seed and Palmer Amaranth [PDF]
, 2016 Most people are aware of Palmer amaranth seed contamination in native seed mixes. These findings have led to questions about whether cover crop seed might also be a source of Palmer amaranth.

Management of cover crops and soil amendments affect yield outcomes during organic transition
Agronomy Journal, Volume 118, Issue 5, September/October 2026.Abstract This study sought to assess the impact of cover cropping and high rates of soil amendments on crop yield during organic transition. Compost, biochar, or a “50/50” mixture of the two on a C‐equivalent basis were applied at a rate of 8 Mg C ha−1 per varying application regimens, with and without cover crops, at two locations on the North ...

Comparison of methods to recover amaranth weed seeds from manure
Agricultural & Environmental Letters, 2022 One pathway by which Palmer amaranth (Amaranthus palmeri S. Watson) invades new areas is through importation of contaminated livestock feed, which then contaminates land‐applied manure.

Update on Palmer Amaranth in Conservation Plantings [PDF]
, 2017 The 2016 growing season will be remembered by many for the widespread detections of Palmer amaranth across Iowa. While native seed mixes contaminated with Palmer amaranth seed used in Conservation Reserve Program (CRP) fields were the largest source of ...
