Kirkland, K.J.Brandt, S.A.2018-09-222018-09-221987-02-19http://hdl.handle.net/10388/10889A five-year field study was conducted at five locations in west central and north west Saskatchewan to determine the effect of cropping practices on weed populations in a continuous wheat rotation. Fall tillage, normal stubble height, tall stubble, and varying fertility levels (N and P) did not directly influence populations of grassy and broad-leaved weeds. In general, there was no significant differences between the herbicide combinations on grassy and broad-leaved weed populations at any of the five sites. Diclofop methyl (Hoegrass) applied as a tank mix with bromoxynil (Torch) or as a separate application with chlorsulfuron (Glean) or Bromoxynil/MCPA (Buctril M) and Triallate (Avadex BW) applied in the fall, followed by 2,4-D amine in the spring all reduced weed populations significantly. Yield increases from the application of Hoegrass plus Glean, Hoegrass/Torch, Hoegrass plus Buctril M and Avadex + 2,4-D were 21, 22, 19, and 15 % respectively.enAttribution-NonCommercial-NoDerivs 2.5 CanadaPresentation
