the plant beneficial effects of metarhizium species correlate with their association with roots. | metarhizium species have recently been found to be plant rhizosphere associates as well as insect pathogens. because of their abundance, rhizospheric metarhizium could have enormous environmental impact, with co-evolutionary implications. here, we tested the hypothesis that some metarhizium spp. are multifactorial plant growth promoters. in two consecutive years, corn seeds were treated with entomopathogenic metarhizium spp. and field tested at the beltsville facility in maryland. seed treatment ... | 2014 | 24805846 |
