TLDR
Soybean disease loss estimates were compiled for the 1996 to 1998 harvested crops from all soybean-producing states in the United States based on field surveys, information from field workers and university extension staff, and research plot data.Abstract:
Soybean disease loss estimates were compiled for the 1996 to 1998 harvested crops from all soybean-producing states in the United States. Scientists from each state provided estimates of losses based on field surveys, information from field workers and university extension staff, and research plot data. Total yield losses caused by soybean cyst [Heterodera glycines Ichinohe] in the United States were greater than those caused by any other disease. Next in importance were phytophthora root and stem rot [Phytophthora sojae (Kaufman & Gerdemann)], brown stem rot [Phialophora gregata (Allington & Chamberlain) Gams], sclerotinia stem rot [Sclerotinia sclerotiorum (Lib.) de Bary], and seedling diseases. Yield loss estimates due to particular diseases varied by region and among years. The estimated soybean yield losses to diseases in the United States were 10.9 × 106 t in 1996, 11.9 × 106 t in 1997, and 14.0 × 106 t in 1998.read more

TL;DR: The simultaneous genome-wide analysis of gene expression changes in the host and pathogen during a compatible interaction provides new insights into soybean responses to nematodes infection and the first profile of transcript abundance changes occurring in the nematode as it infects and establishes a permanent feeding site within a host plant root.

Regional Assessment of Soybean Brown Stem Rot, Phytophthora sojae, and Heterodera glycines Using Area-Frame Sampling: Prevalence and Effects of Tillage.
TL;DR: The prevalence of brown stem rot, H. glycines, and Phytophthora sojae in the north central United States was investigated during the fall of 1995 and 1996 and both the prevalence and population densities were consistently greater in tilled than in no-till fields in all states for which tillage information was available.
