Plants can be damaged by many biotic (living) factors including insects, microbes, nematodes, and larger fauna; but they can also be harmed by abiotic (nonliving) issues, causing problems that are termed "abiotic disorders". Approximately half of the samples that arrive in plant diagnostic clinics suffer from such disorders, including unfavorable soil properties, fertility imbalances, moisture and temperature extremes, chemical toxicity, and physical injuries. Mike Leventry, an ISA certified arborist and owner of Verdant Plant Health Care, discusses how abiotic disorders can significantly diminish tree health and predispose them to diseases caused by infectious microbes. Learn how to successfully identify these disorders in the field, develop management strategies to prevent them, and improve plant health care programs to keep trees living longer. Morning lectures are followed by afternoon site visits featuring examples of abiotic plant disorders. Lunch is included in the cost of the workshop.
