Latent infection of Brassicaceae in the field by Leptosphaeria maculans (blackleg)

1995-01-01

Abstract excerpt

Commercial canola (Brassica napus) crops and cruciferous weeds growing nearby were sampled periodically in 1992 and 1993 for Leptosphaeria maculans, the causal agent of blackleg disease. A virulent (Lm-VIR) and a weakly virulent (Puget Sound: Lm-PS) strain were prevalent in most fields in symptomless petioles and stems of canola from the start of sampling at plant growth stage (GS) 2.4 (rosette) to GS 4.4 (floweri...
