‘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.
FlowerPower is an online tool to predict cereal flowering dates (or cutting dates for oats) 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.

In-crop weed competition causes losses costing around $1 billion per annum for Western Australia. There are very effective strategic and tactical options available to manage weed competition that will increase crop yields and profitability.
Frost damage to braocacre crops is a significant annual production constraint for localised parts of the Western Australian wheatbelt. Different crops will show varying symptoms and be susceptible at a range of growth stages.
