Interpretive Summary: Fusarium root rot, caused by Fusarium solani f. sp. pisi, is a major root rot pathogen in pea production areas worldwide. Here we provide a guide that describes: what the pathogen looks like and the appearance of infected plants, other plant species infected by the pathogen, how widespread is the distribution of the pathogen, how to obtain the pathogen from infected plant tissue and steps to follow to properly identify the pathogen, methods to store the pathogen under laboratory conditions, and methods used to infect plants with the pathogen.

Technical Abstract: Fusarium root rot, caused by Fusarium solani f. sp. pisi, is a major root rot pathogen in pea production areas worldwide. Here we provide a diagnostic guide that describes: the taxonomy of the pathogen, signs and symptoms of the pathogen, host range, geographic distribution, methods used to isolate and identify the pathogen from host tissue, means of maintaining viable cultures of the pathogen, and inoculation techniques that can be utilized under greenhouse or field conditions.
