Control of Canada Thistle and Field Bindweed in Asparagus

  • A. G. Ogg (a1)

Abstract

Canada thistle [Cirsium arvense (L.) Scop.] and field bindweed (Convolvulus arvensis L.) were controlled in asparagus (Asparagus officinalis L. ‘Mary Washington’) fields by repeated applications of dicamba (3,6-dichloro-o-anisic acid) at 0.6 kg/ha or 2,4-D [(2,4-dichlorophenoxy)acetic acid] + dicamba at 1.1 + 0.3 or 1.1 + 0.6 kg/ha. Applications of 2,4-D + dicamba at 1.1 + 0.6 kg/ha in early May and again in mid-June controlled 97% of the Canada thistle in asparagus fields. A third application about August 1 was required to give similar control of field bindweed. Rates of dicamba exceeding 0.6 kg/ha injured the asparagus.
