Zinc deficiency predisposes winter cereals to Rhizoctonia root rot locations
Aims

To identify the link between zinc deficiency and Rhizoctonia bare patch.

Key messages
  • Correction of zinc deficiency in a barley crop increased grian yield and reduced Rhizoctonia bare patch.
  • In glasshouse experiments, increasing wheat shoot zinc to 20 mg/kg dry matter strongly suppressed damage to roots by the Rhizoctonia fungus.
  • Experiments also showed that the zinc was ot toxic to the fungus but instead improved root growth.
