While a cereal crop can shade broadleaf weeds, the weeds will still move their leaves to get the maximum benefit from any sunlight reaching them through the crop canopy... Crops sown in an east-west orientation are less successful in suppressing the growth of broadleaf weeds compared with grass weeds... Crop orientation will have a greater impact on farms in southern Australia, compared to northern Australia...

The benefits improve crop health and crop competitive ability against weeds and the effectiveness of pre-emergent herbicides... When used as a post-emergent product, little of the herbicide gets to the roots and the control of established weeds is often very poor... benefits arise when the weed is prevented from setting seed as there are no increases to the seedbank and, as a consequence, fewer weeds in the future...

A positive test result confirms the need for alternative tactics or herbicides... Assessing weed population density The most accurate way to estimate the population of a weed in a paddock is to count the number of plants in an area of known size at a number of locations... Estimating potential weed population density Potential weed population density can be estimated in a number of ways, such as: When weeds are setting seed, count the number of seed-heads or pods, and the number of seeds per pod or seed-head, from a given sample area...

The management change required to reduce the impact of these weed issues can be summarised as an 'increased focus on driving the weed seed bank down over time using a more diverse range of weed management tactics.'.. The purpose of the project is to have weeds extension professionals work with northern region weeds researchers to reduce their time load on extension and communication activities... Working alongside northern Weeds Researchers from DAFF Qld, NSW DPI, NGA, GOA and the CQGSG, project officers will ensure they are intimately familiar with the latest weeds research outcomes of the groups...

The aim of the project is to further develop, improve and validate the Weed Seed Wizard, the weed seedbank management tool that was developed in the Weed CRC and to encourage its adoption by researchers, growers and consultants... This in turn, can force paddocks out of profitable grain production for a number of years Controlling weeds and minimising their impact depends on understanding and managing the weed seedbank... The project will produce a user-friendly weed seedbank management tool, The Weed Seed Wizard, which will give growers an insight into the weed seedbank and to allow them to coordinate their long-term weed management...

The Weed Seed Wizard is a computer simulation tool designed to help gr owers understand and manage weed seedbanks specific to their farms... Thank-you to GRDC for funding this project and to the rest of the Weed Seed Wizard team; Gurjeet Gill (Uni of Adelaide, Hanwen Wu and Eric Koetz (DPI NSW) and John Churchett and David Thornby (DEEDI Qld) for their input into the model...
