The trial shows clearly the impact of Stripe Rust on wheat yield and grain quality. All varieties had their yield depressed as a result of Stripe Rust, with an average yield reduction of approximately 21%. Those varieties with lower levels of resistance to Stripe Rust were more severely affected, with Silverstar for example suffering a 44% yield penalty. The extra profit generated by controlling foliar disease was on average $81.30 per hectare. The worst affected variety by fungal leaf disease (Silverstar) generated a further
$207.72 per hectare profit when sprayed with a fungicide. Stripe Rust had a significant effect of grain quality. Grain test weights and one thousand grain weights were reduced significantly in the unsprayed treatments. There was less effect on grain protein.

Soil tests were conducted which indicated very low levels of nitrogen (practically zero at 0-60 cm) and lower than ideal quantities of Copper and Zinc. This was largely reflecting the 32 year continual cropping history. Consequently 100 kg/ha Granulock CuZn was used at sowing, with 100kg/ha Urea being topdressed on 3C September and 1st October, giving a total of 92 kg/ha nitrogen applied post sowing. |
