Table 1 - Disease rating scales for Fusarium head blight
Scale | Description of the symptoms |
0 | Spikelets free from bleached |
1 | Small Spikelet discoloration covering ˂5% spike |
2 | Small irregular bleached florets with concentric rings covering 5.1-10% spikelets |
3 | Enlargement of infected spikelets that have developed pink, orange, or salmon-colored fungal spores covering 10.1-25% spikelets |
4 | Premature ripening: Spikelets ripen early, resulting in shriveled, lightweight, and discolored grains as a typical blight symptom covering 25.1- 50% of spike |
