Take a look at the fungicides recommended locally for blackspot. Here's a website for a nursery located in Florida that lists of fungicides by cost, disease and danger category: http://www.rosekinggardens.com/faqs/spray_reference.htm Availability of some fungicides depends on what has been approved for use in individual states. Some less toxic but very effective products are also very expensive. So there's a broad range of options available. |
