ENY046: Reducing Fumigant Application Rates and Soil Emissions with Plastic Mulch Technology

Figure 4. Permeability of methyl bromide (Mebr), iodomethane (IOD), two isomers of 1,3-Dichloropropene (Telone®), dimethyl disulfide (DMDS) (Paladin®), methyl isothiocyanate (MITC)( Vapam®, KPam®), and Chloropicrin (PlC), through polyethylene (PE), metalized, virtually impermeable (VIF) and totally impermeable (TIF) plastic mulch films. Higher values indicate higher permeability. Note differences in Y axis scales between panels and mulch film types representing very significant orders of magnitude differences in permeability.
