Researcher(s) Rick Horbury (Bayer Crop Science)
Year(s) 2016
Contributor West Midlands Group
Trial location(s) Site 2, Moora, WA
Control of blackleg with soil and foliar fungicides locations
Aims

To compare crop emergence between treatments.

To compare programs of seed and foliar fungicides for BL control.

To compare yield and $ROI between Canola disease programs.

Key messages

The trial establishment was variable early due to some non-wetting soil and the crop was sown too deeply due to furrow fill from significant rain after sowing. Early crop vigour as a result was low with blackleg further reducing plant establishment; this coupled with high levels of Vegetable beetle damage also reduced the evenness of the plots.

According to the DAFWA sporacle model spore maturity occurred on approximately the 22nd May which meant this trial was at very high risk of significant disease risk as emergence coincided with high spore levels being released from last year’s stubble.
