10931. Cook, R.J., J.W. Sitton, and W.A. Haglund. 1987. Influence of soil treatments on growth and yield of wheat and implications for control of Pythium root rot.. Phytopathology 77:1192-1198.
Thirty-three of 39 wheat fields sampled in eastern Washington from 1983-1986 had high levels of Pythium spp. Soil fumigation eliminated 95-99% of the inoculum and resulted in adult wheat plants that were 3-10 cm taller than those grown in nontreated soil. Solarization and straw burning eliminated 80-90 and 40-50% of the Pythium inoculum respectively and resulted in taller plants. Wheat yields were 13-36% greater in response to fumigation in fields where wheat was grown every other year, 3-12% greater where wheat was grown every third year and 19 and 14% greater respectively in response to solarization and burning.
