What is the best method to stop plant mold & fungus in Florida Plants

I'm new to Florida & just learning to garden here compared to Ohio Gardening. Big difference. Just learning the best methods to control insects on my flowers. With all the rainy weather I have noticed some mold in my gardens but not sure what works best to treat molds and fungus in my now beautiful plants..Looking to learn all I can to control anything that might destroy my gardens.
