Abstract

A series of three experiments was conducted from 1951 to 1963 for the control of western snowberry (Symphoricarpos occidentalis Hook.) in southern Nebraska. Western snowberry was best controlled with 2,4-dichlorophenoxyacetic acid (2,4-D) when sprayed in early full foliage. Timeliness of herbicide application was considered the most important factor in a control program. Excellent control was obtained with 1 to 2 lb/A of the isopropyl ester of 2,4-D in all studies. The triethanol amine salt of 2,4-D was less effective. A 1:1 mixture of 2,4-D + 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) at 1 and 2 lb/A, 2,3,6-trichlorobenzoic acid (2,3,6-TBA) at 1 and 2 lb/A, and 3-amino-1,2,4-triazole (amitrole) at 2 and 4 lb/A were not as effective for western snowberry control as 2,4-D. Mowing was an ineffective method of control.
