Abstract

CGA-43089 [α-(cyanomethoximino)-benzacetonitrile] applied as a seed treatment enables sorghum [Sorghum bicolor (L.) Moench] to tolerate metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide]. Improved tolerance of alexandergrass [Brachiaria plantaginea, (Link) A. Hitchc.] Eleusine spp., proso millet (Panicum miliaceum L.) and rice (Oryza sativa L.) to metolachlor also was demonstrated. Seven sorghum cultivars, representing widely divergent types of germplasm, responded similarly to the safening effect of CGA-43089 when the cultivars were exposed to metolachlor. Treated sorghum seed may be stored more than 1 yr without a loss of safening activity. In these growth chamber experiments, neither extremes of soil moisture nor temperature reduced the effectiveness of the safener. The predominant site of uptake of CGA-43089 is the coleoptile of sorghum seedlings.
