National Priority: FCR-Production of high-quality export-grade fodder
Summary
Stem nematode can be very destructive to oaten hay and has been kept in check by the development of resistant oat varieties. Recently, there has been an outbreak of stem nematode in an oaten hay crop. This project will investigate if stem nematode found in the latest outbreak has overcome the resistance.
The infested paddock will also be grid mapped to determine the extent of the infestation and define a baseline level to assess the rate of decline in subsequent non-host crops; the crop has since been sprayed out and sown to wheat.

Objective summary
The objective of this project is to determine if the stem nematode population from a recent outbreak has overcome the resistance mechanisms in current stem nematode resistant oat hay varieties.
