Dimethomorph activity and its effect on morphology in different oomycete species of economic and veterinary interest

The class Oomycota comprises species that are pathogenic to plants or animals, including humans, and are able to cause severe economic losses in agriculture and aquaculture industry worldwide. The aims of this work were: (I) to test in vitro the activity of DMM on different species of Saprolegnia and Pythium isolated from fish and aquatic environment and (II) to develop a scanning electron microscopy (SEM) protocol assessing the effect of DMM on hyphal morphology of S. parasitica reference strain.
