The reniform nematode (Rotylenchulus reniformis) is a growing threat to the cotton industry. This project aimed to develop knowledge of the pathogen’s epidemiology - information crucial for developing targeted management strategies. Achievements included an understanding of:

1. nematode genetic diversity and cross crop activity;

2. its ecology in Australian soils; and

3. varietal differences between current cotton varieties. In addition, an evaluation of the efficacy of seed treatments as a control strategy found no positive responses.
