Adult plant resistance and strategic fungicide use for integrated management of cereal rust locations
Aims

• To define the expression of Adult Plant Resistance (APR) in a range of wheat cultivars in relation to environmental conditions and growth stage.
• To develop improved strategies for intervention with fungicides in the control of stripe rust and yellow leaf spot in susceptible and resistant wheat, and the communication of the strategies to industry stakeholders.

Key messages

• Where Flutriafol in furrow was used at establishment no stripe rust was observed in the MS-S cultivar Chara until approximately 130 days after establishment at third –fourth node GS33-34.
• In Chara Flutriafol alone was still giving 80% control of stripe rust at the end of flowering, the same level of control achieved with a GS32 application of Folicur (145ml/ha). Where the crop had received a flag leaf spray at booting GS45 (late flag leaf spray) there was 99-100% control of stripe rust on the flag leaf throughout grain fill.
• All fungicide programmes applied to the cultivar Chara produced a significant yield increase (0.74 – 1.64 t/ha or 12-27%). The greatest yield increase of 1.64t/ha was the result of Flutriafol in furrow with two foliar fungicides
follow ups at GS32 and GS45.
• Chara gave an 18% yield increase from the use of fungicide, averaged across all fungicide treatments, Yitpi gave a 2.5% yield increase and Beaufort gave no response despite a late low level stem rust infection.
• Three of the eight fungicide programmes produced significantly higher yields than the fully untreated crop and the flutriafol alone when meaned across the three cultivars, they were the two programmes receiving two foliar fungicides and the flutriafol followed by a foliar fungicide applied at booting (GS45).
