Pythium arrhenomanes causal agent of root rot on yellow maize in Mexico

Here we show that Pythium arrhenomanes is a causal agent of root rot on maize. The pathogen was isolated from diseased root tissue collected from a conventional maize crop in Michoacan, during 2015. For taxonomic identification, the obtained isolate was used for morphological characteristics and molecular analysis (ITS and COXII genes). Pathogenicity tests confirmed that P. arrhenomanes causes root rot on maize plants.
