WESTERN Australian grain growers are being reminded to consider adult plant resistance (APR) to rust diseases when retaining seed this harvest for next year's crop.
A new fact sheet from the Grains Research and Development Corporation (GRDC) will assist growers in understanding how the APR trait works, why it is important in varietal selection, and how this knowledge can make fungicide application decisions easier.
APR to cereal fungal diseases such as rust provides protection in a crop's post-seedling stages.
A fungicide strategy can complement the presence of this APR trait by providing early protection for those parts of the plant most responsible for yield.
The GRDC fact sheet contains wheat varietal ratings for APR to rust diseases and growers are encouraged to select varieties that are rated with at least the minimum disease resistance standard (MRMS), and in high-risk regions varieties rated MR or better are recommended.
