Abstract:
|
Several disease assessments are available but most of these are more qualitative than quantitative.
These qualitative disease indices are derived from arbitrary ratings ranging from zero to a number depending
of the rating. Some of the ratings are subjective and depend on the prejudice of the researcher. The
present disease index (DI = 1.36 + 0.04W) is not only reliable simple but also quantitative and does not
introduce bias in disease assessment. It is therefore recommended for leaf disease assessment.
Key words: Assessment, diseases, index, severity, Telfairia occidentalis, leaf,
