Research Project: Develop Field Methods to Reduce Fumigant Emissions and Improve Fumigation Efficacy Project Number: 5302-13000-011-23
Project Type: Specific Cooperative Agreement

Start Date: Sep 10, 2008
End Date: Jun 30, 2013

Objective:
To develop efficient and cost-effective field management practices to minimize emissions of methyl bromide alternative fumigants from pre-plant soil fumigation while achieving effective pest control.

Approach:
Field management methods that have potential to reduce fumigant emissions and improve efficacy will be tested. Methods including fumigant application (new shank design, and drip. vs. shank application), low permeable tarps, irrigation, and soil amendment with organics as well as combination of these methods will be determined for their effectiveness and feasibility. Field trials will be conducted in air-quality non-attainment areas in California including Ventura County and the San Joaquin Valley. Data on emission rates, total emission losses, distribution of fumigants in soil profile and efficacy on soil pest control will be collected. Monitored data will be summarized to identify good and effective practices that can be adopted in growers’ fields.
