Program 5: Integrated management strategies for Net Form Net Blotch in low, medium, and high rainfall zones
Tender ID: 516175
Tender Details
Tender Description
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.
Detailed information on yield losses across barley growing regions along with integrated disease management strategies are available for SFNB.
However, such detailed information is lacking for NFNB. There is a need to better understand the yield impact of NFNB and to develop improved cultural practices to mitigate its impact.
Growers need information on the potential yield losses of different varieties in different environments including the HRZ, MRZ and LRZ to determine if fungicide management strategies are warranted.
Where fungicides are required, growers need information on cost effective fungicide control strategies, with consideration of sustaining fungicide mode of action efficacy in the ever increasing risk of fungicide resistance development.
As a result, other options need to be investigated. Stubble inoculum loads of NFNB vary significantly following different crop rotations, varieties, fungicide regimes and are directly correlated with subsequent season disease severity and yield loss.
