Abstract/Contents: | "Field experiments were conducted on a silty-clay loam in Corvallis, OR during the summer of 1995 and 1996 to study the effects of soil solarization, spring-planted green manure cover crops, fumigation with metham, and combinations of these treatments on weed seed survival. Annual bluegrass seeds were incorporated into the soil as a bioassay species and soil samples were extracted to determine seed survival to 15 cm deep in the soil. Soil solarization was applied over a 53 to 59-day period using a 0.6 mil clear polyethylene film. Maximum soil temperatures recorded at depths of 5, 10, and 20 cm were 52, 47, and 33 C in solarized soil. Soil samples were collected from four depths after the solarization period in both solarized and nonsolarized plots and surviving seeds germinated in a greenhouse. Solarization reduced annual bluegrass seed survival from 89 to 100% in the upper 5 cm of soil but did not reduce survival below 5 cm. Solarization may have enhanced survival below 5 cm. Cover crops of barley, rapeseed and sundangrass generally increased survival of annual bluegrass seed buried 2.5 to 15 cm deep in the soil. Green manure crops plus solarization did not improve the efficacy of solarization alone and in some cases diminished the effectiveness of solarization. Solarization significantly improved the efficacy of 0.25 rates of metham (230 L ha⁻¹) in the top 5 cm of soil, reducing overall seed survival in the soil by 40% compared to metham alone (230 L ha⁻¹) but only 30% compared to solarization alone. The conventional rate of metham (930 L ha⁻¹) was the most effective and consistent treatment across all depths." |
