A study was made on the effect of certain chemicals and their combinations on the longevity of the leaf disks cut from Populus × euramericana ‘1‐488’and P. alba cv. hickeliana . Benzimidazole and gibberellic acid maintained (up to a maximum of 80 days) the leaf disks better than the others, however, the longevity was dependent on the chemical and the concentration employed. In a factorial experiment of 3 chemicals × 2 concentrations × 2 cultivars × 2 races of the fungus, it was found that. all these factors contributed significantly (P<0.05) to the experimental variance. However, differential effects of the chemicals or the concentrations on the cultivar × race interaction were not observed.
