Fumigation efficacy and emission reduction using low-permeability film in orchard soil fumigation

摘要

BACKGROUND: Many orchards use fumigation to control soilborne pests prior to replanting. Controlling emissions ismandatory to reduce air pollution in California. This research evaluated the effects of plastic film type [polyethylene (PE) or totally impermeable film (TIF)], application rate of Telone C35 [full (610 kg ha(-1)), 2/3 or 1/3 rates] and carbonation at 207 kPa on fumigant transport (emission and in soil) and efficacy.
