Individual plants in an apparently uniform set of capeweed seedlings were found to differ markedly in susceptibility to potassium deficiency when grown in solution culture at a constant potassium concentration of 2.6 �M. Large differences were found in dry weight of tops (8-218 mg), tissue potassium concentration (0.3 - 4.8 %) and total potassium in the tops (23-10 500 �g potassium). Dry weight and percentage potassium were positively correlated (r = 0.859, P<0.001) at 2.6 �M potassium but not at higher potassium ...

Paraquat and diquat were used from 1963 until 1986 to control capeweed and other annual weeds on an alfalfa field at Elmhurst, Victoria, Australia. From 1983, control of capeweed with these bipyridyl herbicides was no longer satisfactory. In experiments conducted on this field in 1986 and 1987, 800 g ai/ha of diquat was required to equal the control of capeweed obtained by 100 g/ha diquat in an adjacent pasture field with no history of herbicide use. There were substantial numbers of a diquat-resistant ...
