Carryover of DPX-PE350 to Grain Sorghum (Sorghum bicolor) and Soybean (Glycine max) on Two Arkansas Soils
Published online by Cambridge University Press: 12 June 2017
Abstract
Field experiments were conducted to determine carryover potential to grain sorghum and soybean of DPX-PE350 applied POST at 0.05, 0.1, and 0.2 kg ai ha−1 to cotton the previous year. DPX-PE350 did not injure soybean or affect yield adversely. Grain sorghum was injured and maturity delayed on a Sharkey silty clay but not on a Calloway silt loam. Grain sorghum yield was reduced on both soils 16 and 22%, respectively, by residues from the 0.1 and 0.2 kg ha−1 rates of DPX-PE350. In an incubation study, dissipation of DPX-PE350 was greater at 35 C than at 5 C., and did not differ between the two soils.
