The department is a key partner in the Grains Research and Development Corporations' (GRDC) National Frost Initiative (NFI) which aims to provide the Australian grains industry with targeted research, development and extension solutions to manage the impact of frost and minimise seasonal profit v

Preventing weed seed set provides an opportunity to control weed seed set in the pasture, late fallow, late stubble and in-crop phases.

This management strategy provides an opportunity to control weed seed set in the pasture and during harvest. It physically removes viable seed from the paddock by collecting weed seed and grazing crop residues.

‘Risk-aware’ growers can implement strategies to reduce and avoid unnecessary introduction and spread of weeds. These strategies will reduce not only the likelihood of introducing new weed species but also the risk of importing herbicide resistant weeds.

Flower Power is an online tool to predict wheat flowering times of up to three different varieties at the same time and the risk of frost or heat stress in your location. Use this information to support decisions on variety choice and the most appropriate sowing date.

Frost risk occurs virtually every year across southern and eastern agricultural regions. Actual occurrence of frost is determined by location and landscape factors as well as climate.

Silver grass is an annual grass occurring in both cropping and grazing regions across Australia. There are several species, the most common being Vulpia myuros and V. bromoides. These species commonly occur together.

Doublegee or spiny emex is a significant weed in Western Australia. It is a vigorous annual herb with a strong tap root and a long, fleshy, hairless stem.

Barley grass is a common name for Hordeum glaucum and H. leporinum. It is an annual species renowned for rapidly germinating in autumn to provide valuable stock feed soon after breaking rain.

The most accurate way to estimate the weed population of a paddock is to count the number of plants in an area of known size at a number of locations. Use a quadrant, which may be square or circular, to carry out weed plant counts.
