Herbicides are an essential tool enabling cost-effective management of weeds as part of an integrated strategy. Herbicides represent a major input cost for grain growers.
Hence, understanding how herbicides work and the factors which impact their usefulness is critical to maximise the effectiveness of these valuable tools.
Although widely used, herbicides are complex and optimising their effectiveness can be challenging. Maximising herbicide performance becomes especially critical as herbicide resistance increases.
Understanding the science behind how herbicides work in different environments also helps enable forensic evaluation of the causes of spray failures when they occur.
To assist growers and advisers with their decision-making, the Grains Research and Development Corporation has developed, and will continue to produce, resources focused on optimising herbicide use through fostering a greater understanding of their behaviour.
