Effects of Herbicides on Germination and Seedling Development of Three Native Grasses

Two experiments conducted in growth chambers examined influences of 2,4,5-T [(2,4,5-trichlorophenoxy) acetic acid], chlopyralid (3,6-dichloropicolinic acid), picloram (4-amino-3,5,6-trichloropicolinic acid), and triclopyr {[3,5,6-trichloro-2-pyridinyl)-oxy]acetic acid} on germination and early seedling development of buffalograss [Buchloe dactyloides (Nutt.) Engelm.], blue grama [Bouteloua gracilis (H.B.K.) Lag. ex Griffiths], and sideoats grama [Bouteloua curtipendula (Michx.) Torr.]. Germination and plumule growth were largely unaffected chlopyralid but were significantly reduced by 2,4,5-T, picloram, and triclopyr, especially at rates greater than 1.1 kg/ha. Blue grama was less affected by herbicides than either buffalograss or sideoats grama.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
