AB  - Soil fumigation is an important component of U.S. agriculture, but excessive 
      emissions can be problematic. The objective of this study was to determine the 
      effects of agricultural films (e.g., tarps) on soil fumigant atmospheric 
      emissions and spatiotemporal distributions in soil, soil temperature, and plant 
      pathogen control in the field using plastic films with various permeabilities and 
      thermal properties. A reduced rate of 70% InLine (60.8% 1,3-dichloropropene 
      (1,3-D) and 33.3% chloropicrin (CP)) was applied via drip line to raised soil 
      beds covered with standard high-density polyethylene film (HDPE), thermic film 
      (Thermic), or virtually impermeable film (VIF). 1,3-D and CP emission rates were 
      determined using dynamic flux chambers, and the concentrations in soil were 
      measured using a gas sampler. The pest control efficacy for the three treatments 
      was determined using bioassay muslin bags containing soil infested with citrus 
      nematodes (Tylenchulus semipenetrans). The results show that the Thermic 
      treatment had the highest emission rates, followed by the HDPE and VIF 
      treatments, and the soil concentrations followed the reverse order. In terms of 
      pest control, covering the beds with thermic film led to sufficient and improved 
      efficacy against citrus nematodes compared to standard HDPE film. Under HDPE, 
      >20% of nematodes survived in the soil at 30 cm depth at day 12. The VIF 
      treatment substantially reduced the emission loss from the bed (2% of the Thermic 
      and 6% of the HDPE treatments) and eliminated plant parasitic nematodes because 
      of its superior ability to entrap fumigant and heat within soils. The findings 
      imply that not only the film permeability but also the synergistic ability to 
      entrap heat should be considered in the development of new improved films for 
      fumigation.
