This survey was undertaken as part of the project “Introgression of tolerance to Pratylenchus neglectus into annual medics”. The project looked at the root lesion nematode (RLN) Pratylenchus neglectus, which is a root damaging pathogen with an extremely wide host range including all major legume and cereal crops. Lack of resistance or tolerance in crop species causes considerable yield losses that can be worsened in low rainfall conditions as the affected root system is unable to use water efficiently. The survey undertaken was of south-east South Australian lucerne paddocks that had been sown for seed production to assess the impact of soil borne disease. Root damage was found to be common on young lucerne plants. Several fungal pathogens and the nematode Pratylenchus neglectus were short listed as significant in explaining variation in root damage.
This study evaluated the level of resistance to commonly used herbicide groups in three key weeds affecting lucerne seed crops in commercial production areas of...
The lucerne seed industry is an important contributor to Australian agriculture, worth an estimated $95 million per year. The industry is made up of more...
Temperate pasture seed production is concentrated in locations within southeastern Australia and southwestern Western Australia. Lucerne dominates, accounting for about 75% of the area sown...
Building on from earlier AgriFutures Australia-funded research into lucerne seed wasp (LSW), several DNA tests have been developed to give a more precise measure of...
This report summarises the development of DNA tests for lucerne seed wasp (LSW), Bruchophagus roddi, and two associated parasitoid wasps, Idiomacromerus perplexus and Pteromalus sequester,...
Lucerne is an important pasture species in Australia and pest management is critical in seed crops to maximise yield. The Australian crop mirid (Sidnia kinbergi)...
