Final Report: SFS00017 - Optimising cereal profitability in the high rainfall zone through integration of disease management and canopy management principles

Plain text source: 
Through a national series of 40 trials and 20 Soil 2 Grain workshops, this project generated a series of guidelines on the tactical use of agrichemicals and nitrogen (N) in cereals during stem elongation... Disease management outputs included the construction of a green leaf duration calculator for making better fungicide decisions, management guidelines for the use of foliar fungicides to control stem rust in wheat, stripe rust control in wheat varieties with adult plant resistance (APR) and powdery mildew in barley... Using a conservative 5% uptake (based on losses estimated by Murray & Brennan of crops with powdery mildew in WA and leaf rust susceptible barley in the northern region) these guidelines could increase margins by an estimated $5 million/year...
