Young plants may die very rapidly following infection. Infected older plants remain stunted in comparison with uninfected neighbours. Interveinal leaf yellowing and localised wilting occurs, followed by leaf browning, abscission and death. Lower leaves often display symptoms first. Affected patches of plants therefore appear stunted and defoliated.
Crop losses can be very severe.
