GrainSearch’s new export malt type Barley variety Biere is showing its true colours this season in many trial sites across the country.
Photo 1 shows Biere growing at the Southern Farming Systems (SFS) Westmere (Vic) site. Note the excellent ground cover Biere provides. It is very quick once out of the ground and with appropriate sowing rates, can quickly provide weed competition.
Photo 2 shows Hindmarsh at the same site. Note the more open erect canopy that provides more opportunity for the weeds to sneak back in.
Both were sown on the 24th May and Biere is clearly the fastest barley variety at the site and is nearly ready to come into head.
Biere is also showing good disease tolerances so far this season despite the presence of scald and the blotches at many of the sites. Being so fast, it seems that Biere doesn’t stay close to the ground for too long, which possibly minimises early foliar disease loading.
GrainSearch is also conducting some additional trial work this season to check on how Biere performs as a spring sown option (August-October) and whether it can provide a strong yield potential, in the shorter growing season.

Ongoing Rust Susceptibility trials at the University of Sydney have determined that SQP Revenue is now rated as susceptible – very susceptible (S-VS) to the new Leaf Rust (104) pathotype. Reports from Tasmania, Bairnsdale and the Western Districts this season confirm that Revenue will show this leaf rust early in the season (when the weather is warmer). Seed treatments and crop monitoring are essential to ensure Revenue gets off to a clean start each season. A standard rust/septoria control program is normally sufficient to gain good control of the leaf rust and of course, in a good finishing season, Revenue can still reward growers with large yields.
Many other current varieties are now considered susceptible to this new leaf rust, so growers should check with the latest disease ratings guides to ensure they are aware of any changes to their current preferred wheat varieties.
Numurkah Irrigated NVT Main Season Trial – 2015 Results (Snapshot)
GrainSearch’s Manning and Beaufort Wheats performed exceptionally well at the NVT Numurkah (NE Victoria) Irrigated Main Season wheat site in 2015.
Beaufort (long season, red-grained feed wheat) continues to show great adaptability – being able to be one of the top yielding lines in dryland and irrigated situations, over a wide sowing window from Late April to End of May. This result follows from the 2014 trial, where Beaufort topped the site and was one of the few lines to have minimal lodging at harvest.
Manning is a very long season, white-grained feed wheat and is consistently one of the top yielding lines whenever there is moisture available to finish grain filling.

Confirmed reports show that Russian Wheat Aphid (RWA) has spread into parts of Victoria in early 2016.
RWA affects cereals through their direct feeding on the plant. They also inject a toxin that causes the plant to wilt and striping symptoms on the leaves also appear soon after.
Once the RWA is controlled, the plants can generally recover – unlike some of the virus’ spread by aphids (eg Barley Yellow Dwarf Virus).
The RWA can be well controlled with a range of seed treatments and/or spray options. In Victoria, farmers may use sprays currently registered for other aphid control on cereals (following all DO NOT restrictions), whilst in other states, special Permits have been issued by the APVMA to allow growers to control the RWA legally.
Further details can be found from your agronomist, local department of Agriculture or the APVMA website.
As a reminder, Manning wheat – although resistant to BYDV, is not resistant to the RWA or its toxins – they are completely different mechanisms for resistance.
