Overall, barley diseases have the potential to cause very significant costs for farmers... Incidence is 30 per_cent frequency in 30 per_cent of the area, so that the average incidence of the disease affecting the crop is 9 per_cent... Overall, breeding contributes more than 25 per cent of the control for 14 diseases, cultural methods for 32 diseases, and pesticides for six barley diseases...

The stripe rust that infects barley grass is either the wheat-attacking form or a second form that is specialised to barley grass... A form of stripe rust that is specialised to barley grass, known as barley grass stripe rust, can infect some barley cultivars, but the threat it poses is minor... Recent GRDC-funded tests in Mexico have shown that Australian barley cultivars are generally susceptible to the barley form of stripe rust, which means this exotic disease poses a significant threat to the Australian barley industry...

Rust's genetic resistance explored via award.. Professor Park says that pathogens reduce yields of the eight most important crops by a staggering 42 per cent and the most effective, economical and environmentally sound way to control rust diseases is to develop and cultivate varieties with genetic resistance. ".. The rust species can destroy entire crops, with Australia's last outbreak, in 1973, costing the wheat industry an estimated $300 million...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

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...
