Plant Health Webinar: Diagnosis in Ornamental Plants

Plant Health Webinar: Diagnosis in Ornamental Plants
An Overview

Author: Dr David Skydmore, Senior Plant Health Proffesional

In commercial horticulture, plant pests and diseases (P&D) lead to losses in production and subsequent sales losses.

It is important for the grower to be able to detect and identify problems when they arise. A knowledge of the symptoms caused by pests and diseases is necessary for recognising and controlling these problems.

This webinar and technical notes gives an introduction, for the grower, to some of the more common symptoms caused by pathogens and pests and those produced by physiological disorders. Advanced diagnosis techniques are indicated for the specific identification of pathogens.

Terminology used in the Technical Note

• Pest – an animal that causes damage to plants e.g. insect, nematode
• Pathogen – an organism that causes disease in plants e.g. fungi, water-moulds, bacteria, viruses, mycoplasmas. Usually the Latin name of the organism is used.
• Disease – the collection of symptoms that are caused by a pathogen. The disease is normally given a common name that is descriptive of the disease.
• Disorder – a plant problem caused by a physiological disruption e.g. frost damage, nutrient deficiency, water stress.
