Key Points

• Minimising seed set and the introduction of weed seeds is vital to maintain a low weed seed bank
• Depletion of weed seed banks is particularly important for weeds that have a high risk for glyphosate resistance
• Employing a range of tactics as part of an integrated weed management system will help maintain low weed seed banks

Weed seed banks are a major source of on-farm weed woes. By depleting the weed seed bank in the soil, subsequent weed pressures will also be reduced. This is important for all weed species, but vital for weeds that either have or are at high risk for resistance to glyphosate. Farming systems may be able to be manipulated to speed up the depletion of seed banks via promoting emergence, seed decay and predation.
