Extended Data Fig. 9: Synergistic effects between herbicolin A and two tested fungicides, polyoxin B and carbendazim.

Two-dimensional matrix of dose–response for relative mycelial growth inhibition of F. graminearum in the combinations of herbicolin A and polyoxin B (a), and herbicolin A and carbendazim (c). Synergyfinder was used to generate a topographic two-dimensional map of synergy scores for the combination of herbicolin A and polyoxin B (b), herbicolin A and carbendazim (d), respectively. Synergistic and antagonistic dosage zones are highlighted in red and green on the synergy map, respectively. The area with the greatest synergy score is indicated by a white box.
