Research Project: Environmental Impact Assessment of Methyl Bromide Alternative Chemicals

Location: Water Management Research

Project Number: 2034-13000-011-38
Project Type: Specific Cooperative Agreement

Start Date: Aug 16, 2013
End Date: Jun 30, 2016

Objective:
To develop, test, and demonstrate effective and practical field management techniques for nematode pest control with minimal air and water quality concerns in soil fumigation with methyl bromide alternatives.

Approach:
Surface barriers such as extremely low permeability plastic films will be used under field conditions to enhance pest nematode control and reduce fumigant emissions to the air. Soil amendments with natural organic materials such as animal manure or synthetic chemicals will be evaluated alone or in combination with the low permeability films to enhance fumigant decomposition thus reducing emission potential and protect air quality. Application of fumigants with irrigation systems will be tested in comparison with shank injection methods and potential for deep percolation and surface runoff will be evaluated. Impact of soil organic and inorganic amendments on air and water quality will also be measured.
