Technical Abstract: Alternatives to replace methyl bromide in soil fumigation are being actively researched. One of the most probable candidates is 1,3-D dichloropropene (1,3-D). Due to its very high vapor pressure, 1,3-D may diffuse quickly in soil profile after injection and a significant fraction volatilize into the air. However, no information exists regarding the volatilization potential of this fumigant from treated soil, and factors that affect the volatilization rate are yet to be identified. A closed, two-chamber column system was developed and used in determining the effect of application depth, plastic mulch and soil water content on 1,3-D volatilization behavior. Optimized application and soil management techniques through which volatilization of 1,3-D is minimized will be discussed.
