Comparison of commerical standards for the control of sclerotinia in canola locations
Aims

1. Compare the efficacy of Aviator Xpro to commercial standards for sclerotinia control.

2. Compare yield and $return on investment/ha ($ROI/ha)

Key messages

Using the highest label rate of either Aviator Xpro or Prosaro in the first application for sclerotinia lowered the level of sclerotinia infection and recorded a higher $ROI/ha in this trial. Increasing the rate of fungicide increases early activity on active disease but will also increase the length of protection from reinfection. 

The use of higher rates under high sclerotinia disease pressure is recommended not only in a single spray application to extend the window of protection but as recorded in this trial it can provide benefits to a two spray strategy. Improvements in length and strength of sclerotinia control from the use of a higher rate in the first application have been recorded across multiple commercial trials conducted by Bayer Crop Science across Australia in the 2016 season.
