Soybean oil is an abundant and renewable resource through annual crop production. The replacement of paraffin oil with soybean oil in agricultural adjuvants would create an additional market for surplus soybeans and help alleviate dependence on non-renewable petroleum oil. Field and laboratory experiments were conducted to compare effects of a petroleum oil-emulsifier blend (POC) and a soybean oil-emulsifier blend (SBOC) as adjuvants for postemergence herbicides. In field experiments, little difference was observed between POC and SBOC in the ability to enhance control of velvetleaf (Abutilon theophrasti Medik.) with 0.6 or 1.1 kg/ha bentazon (3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide). Control of giant foxtail (Setaria faberi Herrm.) with 0.1 kg/ha sethoxydim )2-(1-(ethoxyimino)butyl)-5-(2-(ethylthio)propyl)-3-hydroxy-2-cyclohexen-1-one) was enhanced more by POC than by SBOC. The effects of adjuvants and relative humidity (RH) on absorption, translocation, and metabolism of the methyl ester of /sup 14/C-haloxyfop )2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoic acid) in corn (Zea mays L.) were investigated. Addition of 1.0% (v/v) POC to the treatment solution resulted in greater foliar absorption and translocation of /sup 14/C than addition of 1.0% (v/v) SBOC.
