- Intervention effect Ammonium nitrate fertiliser reduced area of rhizoctonia bare patch in wheat.
- Intervention effect Ammonium nitrate fertiliser reduced incidence in wheat.
- Intervention effect Ammonium nitrate fertiliser reduced severity in wheat.
- Intervention effect Residual copper from a 1967 fertilizer treatment had no detected effect on area of rhizoctonia bare patch.
- Intervention effect Residual copper from a 1967 fertilizer treatment had no detected effect on incidence.
- Intervention effect Patch area declined from 17.6% without N to 4.2% with 92 kg N/ha.
- Intervention effect incidence declined to 32.7 with N fertiliser.
- Intervention effect severity of rhizoctonia root rot declined to 9.1% with N fertiliser.
- Intervention effect Wheat grain yield increased with adequate Cu despite N above the level considered adequate for nutrition.
- Mechanism The yield response was attributed to control of rhizoctonia bare patch.
- Intervention effect With marginal or deficient Cu, N fertiliser induced Cu deficiency in wheat.
- Intervention effect With marginal or deficient Cu, N fertiliser declined grain yields in wheat.
- Intervention effect With marginal or deficient Cu, N fertiliser reduced rhizoctonia patches in wheat.
