Other claims from this paper (18)
- Intervention effect Mn-EAA reduced glyphosate efficacy.
- Intervention effect Mn-LS reduced glyphosate efficacy.
- Intervention effect MnSO4 reduced glyphosate efficacy.
- Intervention effect Mn-EDTA did not reduce glyphosate efficacy.
- Intervention effect Mn-EAA applied less than 3 d before glyphosate reduced control of velvetleaf.
- Intervention effect The same Mn-EAA timing did not reduce efficacy on giant foxtail.
- Association Antagonism increased as time between applications shortened.
- Intervention effect Antagonism was absent when Mn followed glyphosate by at least 1 d on velvetleaf.
- Intervention effect AMS in glyphosate–Mn mixtures increased control of giant foxtail and velvetleaf.
- Intervention effect EDTA in glyphosate–Mn mixtures increased control of giant foxtail and velvetleaf.
- Intervention effect Citric acid in glyphosate–Mn mixtures increased control of giant foxtail and velvetleaf.
- Intervention effect AMS with Mn-LS on velvetleaf matched glyphosate plus AMS control efficacy.
- Intervention effect Citric acid with MnSO4 on giant foxtail matched glyphosate plus AMS control efficacy.
- Intervention effect EDTA with Mn-EAA on giant foxtail matched glyphosate plus AMS control efficacy.
- Intervention effect AMS generally raised glyphosate efficacy in Mn mixtures at least as much as citric acid or EDTA, with two stated exceptions.
- Association Velvetleaf control declined as Mn from Mn-EAA increased.
- Association Velvetleaf control declined as Mn from Mn-LS increased.
- Association Velvetleaf control declined as Mn from MnSO4 increased.
