Herbicide resistance levels on Kangaroo Island in 2009 locations
Aims

To identify patterns of herbicide resistance levels on Kangaroo Island in 2009.

Key messages

It is important not to rely on a single strategy to keep resistance at bay but integrate them into the crop production program. Some of the key strategies include:

  • Rotation of herbicide mode of action groups within and across years.
  • Keep accurate records of your herbicide applications on a paddock basis.
  • Read the herbicide product label and follow the instructions, always use robust label rates
  • Rotate crop and variety.
  • Identify and monitor your surviving weed populations and check for resistant weeds on your farm. Keep good records of weed populations.
  • If a failure is suspected do not use the same product or product from the same mode of action group.
  • Testing – confirm resistance exists. (For further information on resistance
  • testing contact www.plantscienceconsulting.com.au)
  • Additional cultural weed control techniques to reduce seed banks, e.g. burning, cultivation, delayed sowing,
  • competitive crops and varieties, green manuring, grazing and collection of weed seed at harvest.
  • Control weed escapes before the weeds set and shed viable seed.
  • Do not introduce or spread weeds through contaminated seed, grain or hay.
  • Consider crop and pasture topping.
  • Seek advice from local advisers such as agronomists.
