Here is the Mitigation Strategies for Coffee Rust (Hemileia vastatrix) in Hawaii document, developed by the USDA PPQ Plant Epidemiology and Risk Analysis Laboratory for the current situation in Hawaii. It is somewhat general but it is nice to have the various strategies summarized all in one place. Note that it did not include systemics insecticides because they are not yet available for use in Hawaii. Feel free to use and/or distribute as needed.
