Root lesion nematode (Pratylenchus quasitereoides) populations respond to cereal cultivar locations
Aims

To quantify wheat yield loss in response to root lesion nematode (Pratylenchus quasitereoides) population size, by using a unique population gradient which has been set up as a result of host-crop varieties and nitrogen treatments over the 2018 and 2019 growing seasons.

Key messages
  • The resistance rating of cereal cultivars to RLN species affects RLN multiplication. Yenda wheat is more resistant than Calingiri wheat and these cultivars affected P. quasitereoides population size for two seasons following.
  • In 2019, applying urea increased P. quasitereoides numbers more than applying none, with higher rates upfront at seeding associated with the highest RLN numbers at harvest. Applying urea also significantly increased yield.
  • P. quasitereoides population size reduced over the 2019/20 summer by about half and reduced further over the 2020 growing season when Scepter wheat was grown.
