Supplementary material, Fig 1 Symptoms of red rot at the establishment and grand growth phases. a and b exhibit progression of mid rib lesions (indicated by arrows); c post-germination death of settling; d external discoloration of nodes/internodes; e and f exhibit progression of red lesion intercepted with horizontal white spots on internal side of red rot affected cane stalk; g complete drying of cane top.

Supplementary material, Fig 2 Representative pictures depicting different degrees of disease severity and their respective scores that cumulatively contributed to the disease rating scale of 0-10. a) Drying of leaves (Range of score 0-2); b) External discoloration of nodes/internodes (Range of score 0-1). Arrows indicate discoloration and encircled spots indicate site of inoculation; c) Nodal transgression of red lesion from the point of inoculation (Range of score 0-5). Encircled spots indicate site of inoculation; d) Degree of white spots (Range of score 0-2). Arrows indicates white spots. Encircled spots indicate site of inoculation.
