Abstract
Damage evaluation (assessment of reductions from the crop potential caused by virus diseases) is critical for implementation of economically based, disease management programs.
Types of damage caused by virus infections include direct damage categories such as reduction in growth, reduction in vigor, and reduction in quality or market value and indirect damage related to costs of maintaining crop health.
With ornamental crops, uniform, high quality plants must be produced; damage which affects visual attractiveness needs to be avoided by growers.
Assessment of damage involves experimental measurement of disease damage, surveying the crop for disease, and calculation of the reduction in product or crop value followed by development of methods to predict damage.
Ornamental growers strive for precision in their production practices.
Virus diseases lead to irregularity in production schedules which if corrected can lead to a more stable industry.
