Weed Management in Spring Seeded Barley, Oats, and Wheat with Prosulfuron

Table 4

Visual estimates of percent SINAR weed control at 2, 4, and 8 WAE as well as weed density and dry weight with different rates of prosulfuron alone and in combination with glyphosate on spring cereals at Exeter, Ontario, in 2010-2011. Means followed by the same letter within a column are not significantly different according to Fisher’s protected LSD at 𝑃<0.05^z.
