Control of powdery mildew on irrigated soybeans in southern NSW 2015–16 locations
Aims

A field experiment was conducted in the summer of 2015–16 at the NSW DPI Leeton Field Station to investigate the effect of powdery mildew and four fungicide treatments on the grain yield of two commercial soybean varieties (Djakal and SnowyA) and two unreleased breeding lines (N005A-80 and P176-2).

Key messages

• Powdery mildew infection was observed during the 2015–16 season, although less severe than in previous seasons.
• Powdery mildew infection was found on all soybean varieties except Djakal, demonstrating its known resistance.
• Fungicide applications had no effect on the grain yield of Djakal, N005A-80 or P176-2 varieties, however, the SnowyA variety had a significant increase in grain yield when treated with tebuconazole in a split application regime.
