Other claims from this paper (13)
- Intervention effect A brassica break crop increased wheat yield by 72% over wheat after wheat.
- Intervention effect Fungicide increased wheat yield by a mean 8% in the application year.
- Intervention effect Microbial antagonists increased wheat yield by a mean 6%.
- Intervention effect Chloride increased wheat yield by a mean 4%.
- Intervention effect Fumigation increased wheat yield by a mean 7%.
- Observation Other control methods gave no consistent significant or profitable yield increase or disease control.
- Mechanism Fungicide and microbial antagonists probably failed because treatment stayed in furrows while roots were infected between rows.
- Mechanism Chloride probably failed because background soil chloride was above the response range.
- Mechanism Take-all infection returned after chloride leached from topsoil.
- Mechanism Fumigation suppressed natural antagonists of the take-all pathogen and apparently increased reinfection.
- Observation Take-all pathogen reinfected wheat in the second year after break crops.
- Observation Disease incidence was low after break crops and long fallow.
- Association Pre-sowing inoculum, seedling incidence and whitehead measurements were poorly correlated.
