Abstrakt: The effects of dual infection by maize streak virus (MSV) and turcicum leaf blight (TLB) on symptom expression and pathogen reproduction were measured in one maize variety susceptible to both diseases. Infection by MSV masked symptoms of TLB . There was markedly slower disease progress of TLB on dually infected plants compared with the singly infected plants, as reflected by longer latent period, smaller plant leaf area affected and smaller and fewer lesions in doubly infected plants.
