Disease of the Month

Bacterial leaf streak (BLS) in corn

  • Caused by the pathogen Xanthomonas vasicola pv. vasculorum

  • First identified in Colorado in 2014

  • Symptoms include irregular necrotic lesions surrounded by a yellow halo

  • The bacteria often oozes from the lesions and is spread by rain and hail

  • This pathogen survives in corn residue so control of crop debris and rotation are important management strategies for BLS
