Yields from the Stoddard Solvent plots were more than twice that
of the untreated plot. Other treatments giving similar yield were
Dicryl at 4 lbs. per acre, Dacthal at6 and 9 100. per acre and Zytron
at 10 and 15 lbs. per acre •. Two chemical treated plots gave yields
significantly larger than the Stoddard Solvent treated plot. Those
treatments were Solan applied at 6 and 8 pounds per acre and Karsil
applied at 4 pounds per acre.
Although treatments in 1960 were no.t all. duplicates of treatments
in 1959 the greatest yield in both years. was where Solan waS' applied
at the time carrots had their first true, leaves at a rate of 6 pounds
per acre.
Conclusion
A number of chemicals look promising in comparison to Stoddard
Solvent our recommended practice for the weeding. of carrots. The best
treatments were Solan and Karsil applied at time carrots had- their
first true leaves. Solan looks especially promising for the weeding
of carrots applied at the rate of 6 pounds per acre.
