A new method of applying a preemergence herbicide in sugar beets by sprinklers may reduce costs to growers by eliminating power incorporation. More than 40 percent of Imperial Valley's 65,000 acres of sugar beets are normally sprinkled to achieve germination. Ro-Neet (cycloate) is commonly incorporated by power equipment as a preplant treatment to control troublesome weeds in sugar beets, whether germinated by sprinkler or by furrow irrigation.

The authors wish to thank Stauffer Chemical Company for supplying the herbicide and for its assistance in these experiments
