S-Metolachlor usage in the northern region

S-Metolachlor herbicides have been used in Australian summer crop paddocks for nearly 40 years to control problematic grass weeds. However, an increase in usage and overreliance on the product are raising concerns of potential developing resistance.

In this WeedSmart webinar, we talk to WeedSmart northern extension agronomist Paul McIntosh and Syngenta’s Field Biology Manager Rob Battaglia about how S-Metolachlor (Dual Gold) works, its efficacy, and what potential resistance problems might be around the corner. They explain what tactics growers should adopt to reduce potential resistance problems on this key grass weed herbicide, referring to the WeedSmart Big 6.

Topics covered include:

  • Application considerations for maximum efficacy
  • Incorporation
  • Effect of stubble
  • Herbicide solubility
  • Herbicide binding characteristics
  • Herbicide safener “EPIVIO-C”
