Soil suppression leads to nematode egression

Plain text source: 
DAF Senior Soil Microbiologist at the Leslie Research Facility in Toowoomba, Dr Nikki Seymour said in glasshouse assays, P. thornei increased only 2-5 times in unheated soil compared with 17 times when soil was heated prior to planting to eliminate the general soil biological community... The impact of farm practices on the suppressiveness of soils to RLNs was studied as part of the project with results showing that factors such as pastures in rotation had a limited impact on soil suppression... "Research in the project has identified specific antagonists of the RLN - including some for the first time - in our northern grain growing soils more targeted research is required on how to measure and enhance of these organisms in our soil."..
