Powdery mildew control in soybeans – southern NSW 2014–15 locations
Aims

 To investigate the potential impact of naturally occurring powdery mildew (PM) and four fungicide treatments on the grain yield of three commercial soybean varieties and an unreleased line (N005A-80). 

Key messages
  • Djakal has powdery mildew resistance.
  • Other varieties are susceptible to powdery mildew.
  • New chemistries are effective in powdery mildew control.
  • Split fungicide application can have excellent results.
  • BidgeeA and Djakal grain yields were not affected by powdery mildew.
  • SnowyA and N005A-80 grain yields were reduced by powdery mildew.
