Prosaro 420SC - commerical demonstration of blackleg control in Cobbler TT and Jardee HT canola locations
Aims

To demonstrate the crop safety and efficacy of Prosaro 420SC applied by grower machinery for the control of Blackleg in Canola.

Key messages
  • At application the canola was growing well although there were blackleg lesions on the older leaves across both varieties in the paddock which was the reason the 450 mL/ha rate was selected.
  • There had been no canola grown in the trial paddock in recent history with the only canola grown on farm back in 2009 in a paddock located ~ 2 km to the North West.
  • With both varieties rated as MS or moderately susceptible to Blackleg and given the seasonal conditions with a High blackleg disease risk an application of Prosaro would be beneficial.
  • The advantage of using a seed treatment under these conditions can be seen with the Jardee HT treated with Jockey Stayer not having as severe infection early and losing the plant stand. This can be seen in the differences between Prosaro treated Cobbler and untreated with a much bigger yield increase (see attached report).
