Foliar fungicides for cereal leaf disease control locations
Aims

To test a number of fungicides at different crop growth stages to determine the impact of foliar diseases on grain yield and quality.

Key messages
  • Foliar fungicides appear to increase the yield and economic return for susceptible wheat cultivars such as Kellalac, where leaf rust (Puccinia recondita) is present at low to moderate levels.
  • An application of fungicide at GS39 (flag leaf stage) to Kellalac at Gnarwarre, appeared to give adequate fungal leaf disease control. 
  • Due to the late onset of leaf disease at the Gnarwarre site, there appeared to be little economic benefit derived from the additional fungicide application to Kellalac at GS32.
  • Barley (var Gairdner) responded well to the use of foliar fungicides, despite the relatively low level of disease infection. This could be due to maintaining a green stem for longer.
  • Even at a low disease site (Hamilton), there appeared to be some yield benefit from using fungicides to prolong the greenness of the plant leaf and stem.
