Phytophthora Rot of Soybean

A. F. Schmitthenner

01 June 2000

Management Recommendation(s)

Phytophthora root and stem rot may cause plant stand losses and complete yield reductions in very susceptible soybean cultivars. The severity of losses depends on cultivar susceptibility, rainfall, soil type, tillage, and compaction. Soybean is the only important host of the causal fungus. Integrated control, which combines high tolerance, improved drainage, and tillage, is as effective as resistance or fungicides in most soil environments.
