[NBC] Program 5 - Integrated management strategies for Net Form Net Blotch in low, medium, and high rainfall zones.
Net form net blotch (NFNB) is an important foliar fungal disease of barley that decreases grower profitability by impacting yield and quality. Yield losses in susceptible varieties can range from 18-31%. Generally, less prevalent than Spot form net blotch (SFNB) over the last decade, NFNB is becoming increasingly common since the widespread cultivation of susceptible varieties. There is a need to better understand the yield impact of NFNB and to develop improved cultural practices to mitigate its impact.
This investment will develop and deliver cost effective IDM strategies for NFNB across all rainfall zones of the Northern and Southern regions by:
This investment will develop and deliver cost effective IDM strategies for NFNB across all rainfall zones of the Northern and Southern regions by:
- Determining the impact of NFNB by measuring the yield and quality loss incurred in response to the different IDM strategies.
- Investigating the decline of NFNB inoculum levels of stubble over time and in different growing environments.
- Developing integrated disease management strategies and determine the cost benefit for implementing IDM strategies in each rainfall zone.
- Developing and delivery of an extension strategy to drive grower adoption.
