Synergistic Inhibition — Strobel and Porter

Figure 1. Synergistic inhibition of Botnjtis cinerea (BC) mycelial growth in potato-dextrose agar PDA amended with 

 sodium salicylate (SA) and/or paraquat (PQ). Pictured are all three replicate plates from the SA 2.0 mM-PQ 4.0 mM 

 ( 1/400 X) subset of a larger experiment whose data are presented in Table 3. The leftmost column of Petri plates 

 (column 1) shows growth of BC in the absence of SA and PQ. Column 2 shows growth of BC in the presence of 2.0 

 mM SA. Column 3 shows growth of BC in the presence of 4.0 mM PQ. Column 4 shows growth of BC in the combined 

 presence of 2.0 mM SA and 4.0 mM PQ. 



Table 4. Synergistic inhibition of Botnjtis cinerea mycelial growth in a liquid glucose-salts medium amended with 

 sodium salicylate (SA) and cupric chloride (Cu). Data are of two replicate trials in which each SA-(ai treatment 

 combination was represented twice in each of three replicate 24-well culture plates (n = 6 for each treatment com- 

 bination). Values presented are mean ± standard error extent of radial mycelial growth (mm) from inoculum plugs, 

 measured at 72 hours or 48 hours after BC inoculation (Trials I and II, respectively). Other abbreviations: OPC, 

 observed percent of control; SYN, synergistic interaction.
