摘要： Slow-flow, modified ethyl formate compositions and methods for their use as pre-plant soil fumigants (controlling nematodes and other pathogens) are provided. The modifications include adding to ethyl formate a viscosity modifying thickening agent, and one or more substances which function as a co-solvent and dilution agent (the co-solvent and dilution may or may not be the same). The thickening agent increases the viscosity thereby slowing its flow or rate of transport through the soil. The co-solvent functions as the primary solvent for the viscosity modifying thickening agent. The dilution agent does two things. First, it is used to reduce the partial vapor pressure of the ethyl formate in the formulation, thereby slowing its evaporation rate. Second, it also slows the rate and amount of decomposition of the ethyl formate. The SFMEF compositions and methods do not have harmful ozone-depleting side effects and break down into two naturally-occurring, environmentally-friendly components. Thus they are useful as replacements for methyl bromide and other known ozone-depleting and/or highly toxic soil fumigants.
