susceptible wheat variety

Categorised under:

Catalogue: GRDC Updates
Sowing a susceptible wheat variety on stubble of a previously infected susceptible variety (e.g. Gregory-on-Gregory) represents a much higher risk for developing high levels of yellow spot... The incidence and severity of yellow spot increases as moisture periods lengthen such that it takes repeated rain events to drive the disease from the lower to the upper canopy later in the season... Yellow spot is generally considered a significant disease in very wet seasons (e.g. 1998 and 2010) where yield losses of up to 30% have been recorded in susceptible wheat varieties...

Changes in Septoria tritici blotch resistance to fungicides have been detected in the southern grain growing region, especially where wheat is sown into wheat stubble... Two gene mutations in STB detected by NSW Department of Primary Industries indicate resistance to some fungicides (see Case Study)... Currently none of the products with an azole/strobilurin combination in Australia used on wheat are registered for use on STB...

Figure 1 Wheat yields were doubled when grown after two resistant crops.. Best management practices rely on choosing tolerant varieties (that will yield well when nematodes are present), avoiding very susceptible wheat varieties (that build very high populations of nematodes in the soil), and growing resistant crops (to keep nematode populations low)... The most reliable way to tell if nematodes are present on farms is to have soil tested in a laboratory because symptoms of nematode damage can be difficult to distinguish - often attributed to "a dry finish", "a poor season" or "nutrient deficiencies"...

Western Australian growers are encouraged to carefully check wheat crops for signs of powdery mildew following initial reports of the disease this season... Until 2015, wheat powdery mildew had not caused significant widespread damage to the State's wheat crops since the late 1990s and early 2000s... GRDC-supported trials led by DAFWA in 2015 - combined with outcomes from research funded and conducted by Landmark, Imtrade, Liebe Group and Northampton Agri Services - found that timely application of foliar fungicide, as soon as possible after the disease was seen moving up the crop canopy, was more important than product choice...

Yellow spot is prevalent in northern region wheat crops it remains one of the most misdiagnosed wheat diseases... "Fungicides only treat the part of the plant that they come into contact with," Dr Simpfendorfer said... Dr Simpfendorfer said a lot more inoculum was generated on stubbles of more susceptible wheat varieties, such as EGA Gregory and LongReach Spitfire , so the risk of the disease developing was much greater where a susceptible wheat variety was sown on the stubble of a previously infected susceptible variety, such as EGA Gregory on EGA Gregory ...
