Abstract

Four herbicide treatments applied in the spring or fall were evaluated for leafy spurge control and forage production in eastern and western North Dakota during a 5-yr experiment. All treatments gradually reduced the leafy spurge infestation at both locations except 2,4-D at 2.2 kg ae ha-1 applied annually in the spring or fall and picloram plus 2,4-D at 0.28 plus 1.1 kg ae ha-1 applied annually in the fall. The most cost effective treatment was picloram plus 2,4-D applied annually in the spring which provided a net return of $284 and $108/ha in eastern and western North Dakota, respectively, and averaged 80% leafy spurge control. Picloram at 2.2 kg ha-1 was reapplied only when leafy spurge control declined to less than 70% and provided a net return of $96/ha in eastern North Dakota, but a net loss of $235/ha in western North Dakota. Dicamba at 9 kg ae ha-1 was applied up to four times to maintain 70% control with an average net loss of $458/ha. Total potential production and value of forage will determine if a specific treatment is cost effective in any one location.
