Modern landscapes host many agents that depreciate trees and shrubs – not just infectious diseases or attacking insects. Diseases caused by abiotic agents like weather, soil, and mechanical injury, can compromise plants and result in millions of dollars in losses. Many plants are installed with pre-existing conditions that cause them to be depreciated further by poor planting procedures and unfavorable site conditions. This seminar will address modern landscape realities: its unnatural basis, and the role of temperature, site conditions, and chemicals in causing plant decline and death. Common abiotic diseases that are routinely experienced will be identified and discussed. There will be time for questions throughout the class.
