Mullewa trials - herbicides for selective spot spraying application on summer weeds -  Afghan melons locations
Aims
  • To assess current and novel herbicides and mixes at elevated rates to achieve fast control of summer weeds through weedseeker selective spot spraying..
  • To plant trial plots to wheat to assess carryover or plantback issue with these treatments.
Key messages
  • Weed sensing and selective spot spraying with machinery such as the WEEDSEEKER and WEED-IT selective spot sprayers has allowed for very cost effective broadacre spot spraying of weeds without spraying the whole pad-dock area.
  • Selective spot spraying of hard to kill summer weeds is one application where this technology has a potential to save growers significant funds usually allocated to herbicides.
  • Elevated rates of non-traditional or previously cost prohibited herbicides of a different resistance group can now be used to achieve much more reliable and faster control of weeds.
  • Alliance, Gramoxone, Basta, Roundup Powermax and Ally provided acceptable levels of control on large Roly Poly at high rates suitable for selective spot spraying.
  • Hammer and Sharpen did not provide acceptable control of Roly Poly after initial impressive weed burndown.
  • Roundup Powermax, Garlon, Grazon, Kamba 500 and Tordon 75D all provided excellent Afghan Melon control.
  • Grazon, Kamba 500 and Tordon 75D caused herbicide toxicity issues in the wheat crop as per trial report.
