There is considerable advantage to a Borax treatment since fertilizers usually
contain enough fertilizer grade Borate to supply 40 lbs • borax per acre as
was Bupplied with the 13.8 lb. Boron rate of Solubor and Fertilizer borate.
The 27.8 and55.6 Boron rates could leave toxic residues in the soil that would
affect other .crops-grolhl in rotation with beets.
As the season progressed Be~ts overcame the earlier stunting effects caused
by Boron. .

Discussion: Expt. II
These data would indicate that table beets have a higher degree of tolerance
to Stauffer 2061 than to Eptam. Beets pl~nted'~he day ef application showed
only slight stunting from 2061 as compared to I1lmost complete crop destruction
by Eptam.
Eptam at equivalent rates gave better weed control than Stauffer 2061 •
