Keeping Glyphosate at the top of its game in the Esperance Port Zone - Cascade, WA

This workshop at Cascade is aimed to give growers and agronomists the knowledge and skills to maintain the effectiveness of glyphosate on the farm.

Speakers include Andrew Heinrich, Farm & General, Craig Brown, Synergy/Craig Brown Consulting, Mick Daw, CBH and Andrew Storrie.

 Random glyphosate resistance surveys detect levels between 2-4% of samples as resistant while those submitted by agronomists and farmers regularly show resistance in 25% of samples. Polls on Twitter tend to show even higher levels of resistance on participants’ farms.

With 17 glyphosate resistant weed species currently in Australia this will increase along with the incidence of paraquat resistance resulting from its increased use. Cases of resistance to multiple modes of action are also increasing.

The Esperance port zone has a higher incidence of summer rain than most areas of southern Western Australia. Additional summer rain means more spraying. This has the potential to increase incidence and severity of glyphosate resistance without weed management plans in place that counter the resistance development. It is imperative that Esperance growers understand the threats being faced with the potential loss of cheap and effective herbicides and learn management techniques and tools to achieve long-term effective weed control.

Topics include:

  •     Pesticide residues in grain in the Esperance Port Zone
  •     Resistance status around Esperance / world for the local species, or their close relatives
  •    Review of resistance mechanisms
  •    Resistance testing – why, how and where?
  •    Summer fallow management alternatives by major weed
  •    Double knocking during summer – making it work
  •    Crop-topping – glyphosate alternatives by crop
  •    An update of alternative / new technologies - non-chemical control methods, weed seeker, microwave, flame, steam etc.

RSVP - by Friday 21 September 2018

  These workshops are free and supported by GRDC and the WA Regional Cropping Solutions Network.

Keeping Glyphosate at the top of its game in the Esperance Port Zone - Condingup, WA

These workshops are aimed to give growers and agronomists the knowledge and skills to maintain the effectiveness of glyphosate on the farm.

Currently in Australia there are 17 species resistant to glyphosate and another 10 populations resistant to the other major non-selective herbicide paraquat.

This has the potential to threaten no-till farming in Australia.
