The term 'residual' applies to a number of herbicides that have a long lasting activity in the soil. These herbicides are often applied directly to the soil prior to planting crops, pre-emergent.
This project aims to determine the spread of emerging summer weeds and deliver new knowledge on the biology and management of these emerging summer and winter weeds, with an overall aim of increasi
The viability of annual ryegrass seed can be reduced substantially by desiccation, pre-harvest spraying or swathing of canola depending on the product and timing.
