Assessing the impact of stripe rust control on the yield and grain quality of different wheat varieties locations
Aims
  • To assess the impact of foliar disease control on the yield and quality of different wheat varieties
  • To gather further data on the agronomic performance of various wheat varieties
Key messages

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.

Plot replication Not specified

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.

Herbicide
  • Broadleaf herdicide spray was applied on the 2rd August, Eclipse 7gms/ha + Bromicide Ma + Zinc 250mls/ha + Fastac lOOmis/ha, using 90litres water/ha
  • Grass herbicide spray was applied on the 16th August, Achieve 500gm/ha, Supercharge 1 ltr/ha, using 90 litres waterlha
