Abstract

Methyl bromide, a popular and effective crop fumigant, is being phased out in the United States and globally because of impacts on the ozone layer. Demand for a replacement chemical, 1,3-D (Telone), is expected to increase by up to 500% when methyl bromide is no longer available. However, not all California growers will be allowed to use 1,3-0, as its use has been restricted within townships to address air quality concerns. We estimated the impact of 1,3-0 use restrictions after methyl bromide is phased out in 2005 and found them to be binding in several major production areas of California. Impacts will be greatest in regions where strawberries and perennial crops are grown.
