Modified cobb scale for severity

Definitions
Severity of leaf/stem/stripe rust is recorded as a percentage, according to the modified Cobb scale. As this relies upon observation it cannot be absolutely accurate. Thus it is common to use the following intervals: 0, 5, 10, 20, 40, 60, and 100 percent infection.
