Symptoms of MLN develop distinctly from existing foliar diseases
Mottling and dead heart symptoms (top down) are distinct from most foliar, fungal diseases
Plot level whole plant scoring scale
1 3 5
1 2 3
4 51 = no MLN symptoms 2 = fine chlorotic streaks
on lower leaves3 = chlorotic mottling
throughout plant4 = excessive chlorotic
mottling and dead heart
5 = complete plant necrosis
