Other claims from this paper (10)
- Observation The windshield scouting method was the quickest but the least accurate method for herbicide recommendations.
- Method / resource The range method was more accurate at estimating broadleaf weed densities than grass or sedge weed densities.
- Observation The count scouting method required the most time for completion (30 min).
- Observation The maximum theoretical loss for fields scouted with the windshield method was as high as $528/ha.
- Observation The windshield method gave accurate herbicide recommendations at least 82% of the time in 2003 and 77% in 2004.
- Intervention effect Glyphosate at 280 g/ha or higher significantly injured the peanut plant.
- Intervention effect Glyphosate at 280 g/ha or higher reduced peanut pod yield.
- Association Shikimic acid accumulation was negatively correlated with visual injury and pod yield in peanut.
- Method / resource Shikimic acid accumulation can be an effective diagnostic of glyphosate exposure in peanut at 7 DAT but not at 14, 21 or 31 DAT.
- Observation Theoretical net return for the optimal treatment averaged $867 per ha across sixteen fields.
