1.5	Leaves with lesions ranging from “flecks” to more or less intense chlorosis, accompanied by small necrosis, but without sporulation
2	Chlorotic lesions with sporulation, located in the lower third with very slight (0.1 - 5.0% of the leaves) severity
2.5	Chlorotic lesions with sporulation, located in the lower third with slight (5.01 - 10.0% of the leaves) severity
3	Chlorotic lesions with sporulation, located in the lower and middle thirds, respectively, with moderate-slight (10.01 - 20.0% of the leaves) and very slight severity
3.5	Chlorotic lesions with sporulation, located in the lower and middle thirds, respectively, with moderate (20.01 - 30.0% of the leaves) and slight severity
4	Chlorotic lesions with sporulation, located in the lower, middle and upper thirds, respectively, with moderate-high (30.01 - 40.0% of the leaves), moderate and very slight severity
4.5	Chlorotic lesions with sporulation, located in the lower, middle and upper thirds, respectively, with high (40.01 - 60.0% of the leaves), moderate-high and slight severity
5	Chlorotic lesions with sporulation, located in the lower, middle and upper thirds, respectively, with very high (> 60.0% of the leaves), high and moderate severity
