Methyl Bromide Alternatives – Meeting the Deadlines Reducing Fumigant Emissions After Soil Application
Yates, S. R., Gan, J., Papiernik, S. K., Dungan, R., and Wang, D. 2002. Reducing fumigant emissions after soil application. Phytopathology 92:1344-1348. Volatilization and soil transformation are major pathways by which pesticides dissipate from treated agricultural soil. Volatilization is a primary source of unwanted agricultural chemicals in the atmosphere and can significantly affect fumigan...
متن کاملReducing 1,3-dichloropropene emissions from soil columns amended with thiourea.
Soil fumigants are becoming an important source of volatile organic compounds (VOCs) in air, especially in some agricultural areas. In this study, we used thiourea to construct a reactive surface barrier (RSB) at the soil surface for reducing 1,3-dichloropropene (1,3-D) volatilization. The agrochemical thiourea could rapidly transform volatile 1,3-D to nonvolatile products via an SN2 nucleophil...
متن کاملLeaching potential of persistent soil fumigant residues.
Persistent fumigant residues in soil resulting from agricultural pest-control practices may be released into water and leached to groundwater. In this study, the leaching potential of persistent soil fumigant residues was evaluated, and the effect of dissolved organic matter (DOM) and ammonium thiosulfate (ATS) amendment was investigated. A silt loam soil was incubated separately with the fumig...
متن کاملEffect of drip application of ammonium thiosulfate on fumigant degradation in soil columns.
Low permeability tarps can effectively minimize fumigant emissions while improving fumigation efficacy by retaining fumigants under the tarp. However, when planting holes are cut through the tarps, high-concentration fumigants may be released and result in environmental and worker safety hazards. In a 11-day column study, we explored the effect of drip irrigation application of ammonium thiosul...
متن کاملEffect of surface tarp on emissions and distribution of drip-applied fumigants.
Soil fumigants are used to control a wide variety of soil-borne pests in high-cash-value crops. Application of soil fumigants through drip irrigation systems is receiving increasing attention as a method to improve the uniformity of fumigant application. Little information is available on the emissions and soil distribution of fumigants following subsurface drip application, or the effect of pl...
