How to Treat and Prevent Plant Disease with Fungicide
There are many diseases attributed to fungus which affect flowers, golf course turf, lawns, ornamentals, shrubs, and trees. The following diseases are attributed to fungi: Anthracnose, Brown Patch, Dollar Spot, Leaf Spots & Blights, Powdery Mildew, Snow Molds, and Summer Patch. Stem, crown, and root rot can also be linked to fungal infections. Lawn diseases and turf diseases tend to be highly noticeable because of leaf blight which causes pale yellow or brown patches of grass to develop amongst healthy grass. With some fungal infections, like Necrotic Ring Spot and root rot, the impacted patches of grass, plants, or trees will eventually die. In fact, several--but not all--fungal diseases in plants will lead to the death of the infected area or the entire plant itself.
However, there are fungicides available to combat many lawn fungus and plant fungus species. When selecting fungicides for use on golf course turf and landscape plants, like flowers, ornamentals, trees, and shrubs, it is important to establish a fungicide resistance program by selecting fungicides with different FRAC codes. The Fungicide Resistance Action Committee, FRAC, assigns a code to fungicides based on their active ingredients to help reduce cross-resistance. Cross-resistance occurs when a fungus becomes resistant to a particular fungicide which leads to its resistance to another fungicide with the same target site.
