Aims

To examine the influence of fungicide timing and rate for the prevention of disease and green leaf retention in grain maize.

Key messages
  • There was a significant interaction between fungicide product and the timing of application with propiconazole being more effective than prothioconazole at the later VT timing and visa versa at V8, however there is no evidence that this is a real effect.
  • Application of three different fungicide active ingredients (four products) at either V8 (8 leaf) or VT tasselling produced no yield response at the Kerang site
  • Application of a fungicide at either 8 leaf or tasselling did not result in an extended period of green leaf retention during grain fill.
  • No disease was evident in the trial for the duration of the season. 
Kerang VIC 2019

There was no statistically significant yield response as a result of any fungicide product or timing of application (Table 1). The trial was assessed for any effects or leaf damage 21 days after fungicide application. No damage or leaf discolouration was noted from either fungicide timing on the leaves that received the fungicide. Green leaf retention was assessed at 21, 44 and 64 days after tasselling (VT).

Other trial notes

Important note: that the use of fungicides in this research trial was purely for experimental purposes. The use of active ingredients does not in any way constitute a recommendation or suggestion that the fungicide necessarily has a recommendation for that crop.
