Abstract
Experiments were conducted in the greenhouse and the field to determine if a seaweed extract and its component alginates could enhance the activity of sethoxydim on barley (five- to six-leaf stage). In greenhouse trials, sethoxydim with 0.5% oil concentrate was applied at 0.05, 0.1, and 0.15 kg ai/ha; in field trials, sethoxydim with 0.5% oil concentrate was applied at 0.1, 0.2, and 0.3 kg/ha. In both sets of trials the seaweed extract was applied at a rate of 1 and 2 L/ha, and the alginates were applied at 250 and 500 g/ha. When either the seaweed extract, or the calcium ammonium salt of alginic acid was used as an adjuvant a significant increase in sethoxydim activity was usually observed. At the highest rates of these adjuvants, sethoxydim (0.2 kg/ha) activity increased from 59% control (1321 g/m 2 fresh weight) with only oil concentrate, to 87% control (224 g/m 2 fresh weight) with seaweed extract, or 89% control (184 g/m 2 fresh weight) with the calcium ammonium salt of alginic acid. Sodium salts of alginic acid, both low and medium viscosity, were much less effective.
