Phytophthora sansomeana, an Emerging Threat to Soybean Production

In 1990, new Phytophthora strains, later recognized as a species, sansomeana, were found to cause root rot (PRR) in soybean addition P. sojae. The emergence and spread of second pathogen causing PRR poses significant threat production. While genetic resistance sojae has been developed widely deployed management tool, these varieties appear largely ineffective at controlling which broad host-range can infect survive on non-leguminous hosts including fir trees, Rosaceous fruit maize, several herbaceous weeds. This contributes potential for distributions worldwide across both agricultural natural ecosystems. Despite having studied since the 1980s under variety informal designations, little is known about epidemiology, host-interactions, this emergent pathogen. Due lack options, increased frequency first reports geographic areas, overall limited body knowledge surrounding novel pathogen, sansomeana warrants more research attention from biological disease perspectives. aim review summarize hosts, distribution, pathogenicity, current strategies provide concise record where it other designations. Its role emphasized due economic magnitude PRR-associated losses its well-documented aggressiveness
