A petal survey for Sclerotinia in canola across NSW and northern Victoria locations
Aims

Some districts in NSW and Victoria are known to frequently develop Sclerotinia stem rot. The purpose of conducting the petal survey was to identify if there are significant differences in the level of petal infestation between districts where the disease develops frequently, compared with those districts where the disease develops once every few years. This information will indicate what influences disease development, background inoculum levels or environmental conditions, or both. 

Key messages
  • Sites in the Riverina, Cootamundra, Cowra and Grenfell developed high levels of Sclerotinia-infested petals during the flowering period in 2015.
  • No correlation was found between individual districts and petal infestation levels.
  • The amount of rainfall during flowering was positively correlated to the level of inoculum.
  • Rainfall during flowering is not the only factor that determines the level of petal infestation. Other factors such as initial inoculum level (from sclerotia), crop height, crop-canopy density and paddock history play a significant role.
