Effects of Adjuvants on Behavior of Metribuzin in Soil and Soybean Injury
Published online by Cambridge University Press: 12 June 2017
Abstract
Three adjuvants, ARD 54, ARD 93, and ARD 1836, were evaluated for their ability to reduce metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] phytotoxicity to soybeans [Glycine max (L.) Merr.] in sandy soils. A reduction in metribuzin phytotoxicity was observed, usually without reductions in sicklepod (Cassia obtusifolia L. # CASOB) control. The addition of linseed oil to a spray suspension containing 1% ARD 1836 reduced sicklepod control slightly at one of two locations. The addition of these adjuvants and linseed oil to the spray solution had no effect on soybean yield. These adjuvants slightly reduced movement of metribuzin in thin-layer soil chromatography but had no influence on sorption in batch-equilibrium experiments.
