Brown Stem Rot - Agronomic Impact
Yield losses to BSR of 10-30% are common. BSR may reduce both seed number and seed size. Severely diseased plants may wilt, defoliate prematurely and lodge more readily than non-infected plants.
Yield loss is greatest in cultivars with a longer relative maturity and if foliar symptoms as well as stem symptoms are present.
