- Intervention effect One tridemorph spray raised yield by 540 kg/ha or 12·1 per cent over unsprayed crops.
- Intervention effect Two or more sprays raised yield by 703 kg/ha or 15·6 per cent.
- Observation More susceptible cultivars had the greatest yield increases.
- Association Crops near winter barley had higher yield increases than those not near it.
- Intervention effect Crops near winter barley responded best to early sprays.
- Intervention effect Other crops responded best to later sprays.
- Association A cumulative mildew index gave the best relationship between mildew and yield increase.
