Cereal Rust Report, Season 2012, Volume 10 Issue 2

Mild and moist summer conditions in certain regions in 2011-12 encouraged opportunities for green bridge development and potential for cereal rust survival. Good subsoil moisture and opening rains also provided the 2012 cropping season with an ideal establishment period in many regions. With these conditions in view, it is not surprising that stem rust has been observed in stubble regrowth situations and crops in WA over recent months, with three unconfirmed sightings in June in the Esperance-Scaddon area. Wheat leaf rust was recorded in southern NSW in mid May. The first report of wheat stripe rust was made in early June 2012 from Lake Cargelligo (southern NSW), with two subsequent detections from Nyngan in northern NSW and Grenfell in central NSW in late June. In all cases it has been early sown varieties that have recorded the first stripe rust infections for the season.
