The Australian National Frost Program (ANFP) was established in 2012 by UA, DAFWA and GRDC. Frost sensitivity ratings are being developed for current wheat and barley varieties to assist growers manage the risk of frost... Reductions in grain number start to occur in wheat and barley when canopy temperatures at flowering are around 0 and -2 C respectively with no visible signs of frost damage... Canopy temperatures at flowering below -4 C and -6 C in wheat and barley respectively can cause major crop losses...

With frost damage now estimated to be costing growers $360 million a year, the Australian National Frost Program (ANFP) is broadening its assault on the issue... Dr Juttner says methods varied across the country, so the results could not be compared... Dr Juttner says the method ANFP researchers have now developed involves staggered times of sowing, so that when a frost event hits they can tag individual heads of different wheat and barley varieties, at the same stage of development - in other words, they can compare the effect of frost on different cultivars at a synchronised developmental stage and compare like with like...

Frost puts freeze on effectiveness of ryegrass herbicide.. "Ideally, spray small ryegrass plants under warmer and frost-free periods for the best results with clethodim on ryegrass," said Dr Gill when addressing a GRDC Grains Research Update in Campbell Town, Tasmania, on the topic of controlling herbicide-resistant annual ryegrass in canola crops... We want the ryegrass to be actively growing and stress-free for clethodim to do the best job, so growers need to watch the weather forecasts closely to determine the best time to spray," Dr Gill said...

The project has supported the development of farming systems that incorporate forage (lab lab) and ley (butterfly pea) legumes into grain farming systems... Growing canola is like having a fallow period as far as VAM populations in the soil are concerned... Research in the area of AWM is looking at tactics that can be implemented during the summer...

Search for answers continues as frost bites in 2012.. Significant grain crop losses caused by frost in 2012, confirmed at harvest time, add to the sense of urgency to seek solutions to this issue - a major concern for most Western Australian grain growers... The scale of losses caused by frost is a prime reason for frost being a major priority for the Grains Research and Development Corporation (GRDC), which is funding different areas of frost research, development and extension (RD&E)...

Grain growers throughout the southern cropping region are advised to expect a heightened risk of frost this season due to the developing El Ni o climate event... Dr Hayman, who is involved in frost research projects being funded by the Grains Research and Development Corporation (GRDC) through its National Frost Initiative, said while the risk of frost was expected to be increased this year, the exact timing and frequency of frost events could not be predicted... The GRDC is continuing its long-term commitment to funding frost-related research, with its recently launched five year National Frost Initiative focused on identifying and delivering practical genetic, management and environmental solutions to assist growers to manage the impact of frost...

Single trait may give wheat a bulletproof vest.. "The lines that contain the QTLs for drought and shading tolerance will now be tested in future trials for tolerance to other stresses such as heat stress, to confirm that the tolerance trait is shared by different stresses," Dr Dolferus says... The material is ideal for getting a better understanding about what is happening 'under the bonnet'."..
