Topaz Fungicide does not list coffee as a tolerable crop species to treat on the product label. We recommend that you check the fertilizer you are also applying as some can promote further disease development/persistance.
The label for Topaz Fungicide states "Bermudagrass can be sensitive to TOPAZ® Fungicide. Do not exceed 1.44 fl. oz./1,000 sq. ft. every 30 days on any variety of bermudagrass. In FL, do not apply TOPAZ® Fungicide to bermudagrass golf course greens when temperatures exceed 90°F."
Please view the full product label for more information.
The rate on the Topaz Fungicide will depend on what disease you are treating for, and what plant you are applying it to.
