Fungii and Plant Diseases
Molds, mildews and similar organisms can present a problem in the home, lawn and garden when the conditions are right. If you are dealing with mold or mildew issues in your home or a building visit the Structural Issues Related to Molds, Mildew and other Fungi page.
Issues in the Lawn and Garden
The impact of diseases on plants in the lawn or garden can be determined by many environmental factors including moisture, sunlight exposure, soil conditions and season. Managing diseases will involve evaluating all of these factors and determining what if any environmental changes can be made before utilizing a pesticide. Caution must also be taken in preventing the spread or re-infestation of a plant disease by removing diseased plants or plant debris from the yard or garden. Additionally, care must be taken when obtaining new plants to inspect them for disease or to find disease resistant breeds.
If you need help in identifying or managing a plant disease or mold issues, contact your cooperative extension agent for assistance.
