Description

0

Highly resistant (HR)

No mycelium growth

1

Resistant (R)

Sparse mycelium growth with very little sporulation

2

Moderately resistant (MR)

Slight growth of mycelium is evident macroscopically. Microscopically slight to moderate growth of mycelium with conidiophores of the fungus

3

Moderately susceptible (MS)

Moderate growth of mycelium is evident macroscopically. Microscopically moderate development of mycelium with moderate to heavy sporulation is seen

4

Susceptible

Abundant growth of mycelium is evident macroscopically. Microscopically abundant development of mycelium with heavy to very heavy sporulation is visible
