Abstract
Methods were compared for controlling volunteer horseradish (Armoracia rusticana Gaertn, Mey. & Scherb.) resulting from commercial horseradish production. The most effective treatment was glyphosate [N-(phosphonomethyl) glycine] (4.5 kg/ha) applied in mid-September 6 to 8 weeks after discing. 2,4,5-T [2,4,5-trichloro-phenoxy acetic acid] was also effective, while dicamba [3,6,dichloro-o-anisic acid] and a dicamba plus glyphosate mixture provided less control. Horseradish roots can sprout from 90-cm deep and still be susceptible to a mid-September glyphosate application.

Where plants have been lightly touched with frost, take a hand syringe and spray the vulnerable buds with water before sunlight strikes them.” The following spate of correspondence formed the basis of this “postal symposium.”
