Curly dock

Preemergence control of lawn burweed (Grant et al., 1990 Johnson and Murphy, 1995), henbit (Minner, 1994), short buttercup, hop clover, curly dock, and buckhom plantain (Grant et al., 1990 Chandran et al., 1998) has been reported with isoxaben. However, control appears to be rate dependent with such species as curly dock and parsley-piert.

Oxalis stricta and O. oregana (woodsorrel), Rheum rhabarbarum (rhubarb), and numerous common weeds such as Rumex crispus (curly dock), Chenopodium album (lamb s-quarters), and Amaranthus retro-flexus (red root pigweed). 

The sunflower is also an allelopathic plant, and a sunflower extract was found to inhibit the growth of such common weeds as jimsonweed, velvetleaf, johnson-grass, curly dock, red sorrel, ragweed, purslane, smartweed, wild mustard, and lamb s-quarter. (Creosote bush, or chaparral, may be the outstanding example of an allelopathic plant. No other plant can live next to or under a creosote bush.)... 

In 1990, the Columbia River shoreline within the Hanford Site was surveyed for potential edible natural vegetation and samples were collected for radiological analysis. Table 5-21 shows results for samples of mulberry leaves and berries, and one sample of curly dock collected from the N Springs area. DOE initiated removal of all contaminated vegetation from the N Springs area in September 1990. Mulberry trees and other plants were removed and disposed of in the 200 Area burial grounds. 

In the Northern Hemisphere, most docks are common weeds that thrive in acid soils hence, their presence in a meadow indicates that the land needs lime. The leaves of curly docks (R. crispus) are used in soups and salads, like spinach. 

Fig. 7. Schematic representation of copper transfer from CopZ to CopY. Cu+ ions from two subsequently docking Cu-CopZ molecules are transferred to the trigonal binuclear cluster in CopY, which results in the displacement of the zinc ion and reorientation of the sulfur residues. Bold S residues are in the plane S residues are out of the plane of the drawing. The boldface curly line represents part of the backbone of CopZ and the hue curly line represents part of the backbone of CopY. See text for further details of the transfer intermediates 1-6 (courtesy of Charles T. Dameron).
