| Abstract/Contents: | "Research to date has shown that use of soil surfactants can enhance vertical soil movement and distribution of pesticides. Mefenoxam is a commonly used fungicide for preventative disease suppression of Pythium spp. and its physiochemical properties (Ks = 26,000 mg/L; KOC = 20 to 790) suggest it may readily distribute through the soil profile. In a laboratory experiment, 14C-mefenoxam was quantified within soil column depths (0.0 to 2.5, 2.5 to 5.0, 5.0 to 7.5, 7.5 to 10, 10.0 to 12.5 and 12.5 to 15.0-cm; 90:10 sand:peat by vol) in an attempt to elucidate vertical distribution when paired with a soil surfactant. The evaluated soil surfactant (Cascade Plus) was applied at 0.25% vol/vol (5.15 mL column-1) to unique soil columns 24 hours prior to 14C-mefenoxam (0.76 kg ai ha-1; 186.4 mL column-1) application, which was applied to the soil surface. Immediately following application, 0.635-cm irrigation was applied to all columns and soil collection occurred at 0, 3, 7, 14 and 21 days after treatment (DAT). Regardless of soil surfactant, the majority of 14C-mefenoxam was detected in the 0 to 2.5-cm depth (85.0 to 100.0% of applied), with less detected in the 2.5 to 5.0-cm depth (1.0 to 11.0%). 14C-mefenoxam was not detected beyond 5.0-cm depth across collection timings. Pooled over collection timings, in the 2.5 to 5.0-cm depth, greater C14-mefenoxam was detected when applied with a surfactant (5.8% of applied), compared to 2.9% with no surfactant. Results from this experiment illustrate the importance of adequate irrigation and the potential use of soil surfactants when targeting soil-borne pathogens." |
