Betanal herbicides + HOE-23408 gave excellent postemergence
weed control at several locations particularly from applications
made by Wicks (North Platte Station, University of Nebraska).
Herbicide Effect on Production
Under normal production practices, herbicides have a beneficial
effect on crop production (Table 4) .

Programmed Weeding Systems
Complete chemical weeding is the key to final stand planting and
elimination of clean up labor in beet fields. Programmed or
sequence herbicide applications offer the best chance for weed-
free beets and production improvement. It is estimated that only
: 15-20 percent of Great Western acreage was sequence treated in
.1974. A 40 percent goal achievement should be realized in 1975.
Consult the Sugarbeet Production Guide, page 29 for typical
sequence applications.
