Pythium Soft Rot, Fusarium Yellows, Erwinia Soft Rot and rootknot nematode are all soilborne diseases of ginger and are responsible for serious losses in the crop. Pythium myriotylum, in particular, is a disease first identified by ginger growers in the 2007/08 growing season (Stirling et al. 2009). These diseases not only are a threat to individual growers but also to processors that add value to the crop. Collectively the ginger industry is valued at $2m per annum at the farm gate with a further $76m per annum added as firstorder processing. Last season, however, approximately $2m was lost at the farm gate due to Pythium Soft Rot alone. Previous RIRDC funded research (PRJ005612; PRJ008343) into the control of Pythium Soft Rot in ginger has indicated that some of the critical measures to limit losses are through the use of organic amendments and cultural practices that are thought to improve soil health. In other words, practices that stimulate the buildup of beneficial microorganisms that can suppress ginger pathogens, as well as improve soil structure and fertility, will be assessed using a range of soil health indicators. The Ginger Industry R&D Advisory Committee has voted to extend funding support for research into the control of diseases of ginger. This project attempts to build on research, both past and present, but with an emphasis on understanding how soil health can be improved to lead to more productive and sustainable ginger farming systems. By controlling soilborne pathogens of ginger, losses will be reduced and production made more sustainable.
