The EPA has issued a specific exemption under the provisions of Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to the Florida Department of Agriculture and Consumer Service for the use of FireWall 50 WP to control citrus canker (Xanthomonas citri subsp. citri) on up to 54,000 acres of fresh market grapefruit.
Independent field trials using FireWall have been conducted by Dr. James Graham of the UF/IFAS, Citrus Research and Education Center. Graham reports these trials have demonstrated that alternation of FireWall with a reduced rate of copper provided a similar reduction in diseased fruit with less copper burn (phytotoxicity) than the full rate of copper and that the residual activity of FireWall is greater than copper under tropical weather conditions.
All applicable directions, restrictions, and precautions on the EPA-registered label for FireWall 50 WP must be followed as well as those on the Section 18 label. For more information, email at [email protected] or visit the company’s website.
