Plantation black walnut can become stagnated because of excessive weed competition. A 7- to 11-year-old black walnut plantation was treated with simazine, Roundup, and a combination of the two. After 1 growing season, height and diameter growth increased substantially in the plots treated with Roundup and simazine plus Roundup. Greatest response was achieved by broadcast application. North, J. Appl. For. 4:93-95, June 1987.
