Many of these water moulds are known as ecologically important pathogens of species of plants and animals, including fish, crustaceans, and agricultural crop plants. ''Aphanomyces'' water moulds are "one of the most important yield-limiting factors in production of legumes and sugarbeet."

Some of these water moulds are host-specific, such as '' A. iridis'', which only infects ]iris
Iris most often refers to:
*Iris (anatomy), part of the eye
* Iris (color), an ambiguous color term
