Efficacy comparisons of different antibiotics and fungicides on contamination control. (A) Inhibition of bacterial growth by six different antibiotic treatments. Each plate was inoculated with six different bacterial stains (1–6) that were isolated from contaminated node culture plates. (B) Suppression of fungal contamination by five different fungicides (0.2% bleach, 0.1% AAS, 20 mg/l Natamycin, 0.2% PPM and 5 mg/l Benomyl). Values represent means with standard deviation from three biological replicates, and significant differences are indicated by different letters (P < 0.05, ANOVA, LSD). Node samples for each treatments ranged from 24 to 35
