Other claims from this paper (18)
- Intervention effect A single fungicide application often reduced blight severity under high disease pressure.
- Intervention effect A single fungicide application had no effect on yield under high disease pressure.
- Intervention effect Two chlorothalonil applications reduced ascochyta blight.
- Intervention effect Two chlorothalonil applications increased yield.
- Intervention effect Two azoxystrobin applications reduced ascochyta blight.
- Intervention effect Two azoxystrobin applications increased yield.
- Intervention effect Combined chlorothalonil and azoxystrobin reduced ascochyta blight.
- Intervention effect Combined chlorothalonil and azoxystrobin increased yield.
- Intervention effect Bravo Ultrex was less effective than Bravo 500 against blight.
- Intervention effect Bravo Ultrex was more effective than mancozeb against blight.
- Observation Untreated seed yield at one site was below 5% of the best fungicide treatment.
- Association Disease severity was strongly related to seed yield.
- Observation Seed-borne A. rabiei incidence was 30–;48% under high disease pressure in 2000.
- Intervention effect Early and mid flowering azoxystrobin reduced seed-borne A. rabiei incidence to 7–9%.
- Intervention effect Fungicide application had no impact on seed-borne Botrytis cinerea.
- Intervention effect Fungicide application had no impact on seed-borne Sclerotinia sclerotiorum.
- Intervention effect Fungicide application had no impact on seed-borne Fusarium spp.
- Recommendation The authors conclude that fungicides can complement partial resistance to reduce blight and raise yield and quality.
