Stem nematode in oats


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 nonhost crops; the crop has since been sprayed out and sown to wheat.
