[1] Pythium myriotylum is a causal agent of soft root rot in economically important crops including peanuts, tomato, rye, wheat, oats, cucumber, soybean, sorghum, tobacco, cabbage, and maize.

[1] P. myriotylum has an asexual reproductive cycle that consists of mycelium that produce sporangia.

The zoospores are released during wet conditions so that they can move through the soil to infect new hosts.

[1] A disease caused by Pythium myriotylum is increased in warm regions, or in summer months.

It prefers wet soil conditions in places of low altitude because this is where the water will sit for long periods of time.
