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.
Following the extended dry conditions this autumn, weeds are now emerging and becoming a challenge for growers to manage in paddocks that may have patchy crops, crops with staggered emergence or no
Testing for herbicide susceptibility allows you to determine what herbicide options are still available to control weeds on your farm.
Summer weeds can rob subsequent crops of soil nitrogen and stored soil water. They can also reduce crop emergence by causing physical and/or chemical interference at seeding time.
In Western Australia, rising temperatures and falling water levels over summer encourage algae and aquatic weed growth in farm dams.
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.
Hyssop loosestrife (Lythrum hyssopifolia) is a widely distributed weed in the south west of Western Australia.
