Effect of Herbicides and Handweeding on Establishment of Kleingrass and BuffelgrassBovey, B. W.; Meyer, R. E.; Merkle, M. G.; Bashaw, E. C. (Society for Range Management, 1986-11-01)In the greenhouse, kleingrass [Panicum coloratum (L.) 'Selection 75'] and buffelgrass [Cenchrus ciliaris (L.) 'Nueces'] were tolerant of preemergence application of butylate (S-ethyl bis(2-methylpropyl)carbamothioate) and early postemergence sprays of barban (4-chloro-2-butynyl 3-chlorophenylcarbamate) and siduron [N-(2-methylcyclohexyl)-N′-phenylurea]. Kleingrass tolerated early postemergence sprays of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile), but bromoxynil injured buffelgrass. In the field, the most promising treatments for kleingrass establishment, compared with handweeding, included postemergence sprays of 2,4-D [(2,4-dichlorophenoxy)acetic acid], preemergence application of siduron, and ropewick application of glyphosate [N-(phosphonomethy)-glycine]. Once established, kleingrass seedlings tolerate extreme drought during the growing season where weeds had been controlled.
