Interaction between zinc nutritional status of cereals and Rhizoctonia root rot severity locations
Aims

To examine the relationship between crop Zinc nutrition and Rhizoctonia root rot.

Key messages
  • Severity of root rot of barley and wheat in farmers fields caused by Rhizoctonia was inversely correlated with crop Zn status.
  • Zn was the only nutrient correlated with the severity of Rhizoctonia.
  • Zn deficient plants were more susceptible to Rhizoctonia.
  • 2.5 kg Zn/ha halved the area suffering from bare patch.
