Book Description
Previous surveys in Iowa recovered 12 races of the pathogen between 1966 and 2004. These surveys collected a single isolate from each site. We proposed multiple races could be identified from a single site, based on evidence from Ohio, Arkansas and Australia surveys. Three fields in Iowa with a history of PRR were extensively sampled. Soil samples were baited using leaf disc and seedling baiting methods. A total of 36 isolates of P. sojae were collected. Of those, 32 were identified to race or pathotype. We found multiple races and pathotypes in two fields sampled. Eleven races and 13 pathotypes are reported new to Iowa.

Book Description
Inorganic fertilizer treatments resulted in levels of damping-off similar to manure applications in some instances and it is hypothesized that the swine manure introduced a salt toxicity problem in some instances. To minimize the detrimental effects of manure because of increased disease potential, and maximize beneficial effects, manures should be applied as early in the spring as possible, and at the lowest rates possible. Phytophthora resistant varieties should be used and seed should be treated with af ungicide. The manure should be injected into the soil between soybean rows or broadcast and incorporated immediately.
