What is the significance of including a range of symptoms in samples?

The significance of including a range of symptoms in samples is crucial because certain diseases exhibit varying symptoms at different stages of their progression. By capturing a broad spectrum of symptoms, it allows for a more accurate diagnosis and understanding of the disease lifecycle.

For example, in the early stages of a plant disease, symptoms may be subtle and not immediately indicative of a specific pathogen. As the disease progresses, more pronounced symptoms may develop. If only the most severe or singular symptoms are considered, there is a risk of missing important diagnostic information that could lead to an incorrect or incomplete diagnosis. By recognizing and including symptoms across the spectrum, practitioners can develop a clearer picture of the health of the plant and the nature of the pathogen involved. This comprehensive approach can also guide more effective management and treatment strategies.
