- Plant stunted by verticillium wilt
Minor overall, but can be serious on some farms in some seasons. Often occurs on crops grown on the best soils in the South Burnett and in irrigated crops in low rainfall areas. Infection before early podfill may reduce yield, but the impact is small if leaf symptoms appear after this time.
Pale green blotches appear between the veins and around the leaf margins. The margins then become brown and die. Under dry conditions these areas dry out, giving the plant a scorched appearance. The vascular tissues in stems and roots are discoloured reddish-brown. Wilting and plant death sometimes occur.
Hosts include the weeds cobbler's pegs, noogoora burr and anoda weed and many crop plants.
Once infection occurs, nothing can be done to control verticillium wilt.
