The herbicidal activity and corp selectivity of IG-21 (code number for development HWS) were further examined at 1,200-50 g ai/ha. IG-21 was tested for postemergence activity against a range of plant species including purslane (Portulaca oleracea), slender amaranth (Amaranthus ascendens), goosefoot (Chenopodium album), spiny amaranth Amaranthus spinosus), sugarbeet Beta vulgaris), maize Zea mays) and rice Oryza sativa). Results are shown in Table 2.50.
