When we trial the chemistry in pots against glyphosate resistant ARG, there is plenty of options that works close to 100%. Then there is the real world Matt is battling with 😁🙈
Brown manures needing a rye grass mop up - the size of them shows they escaped the double knock with a decent level of gly resistance ✊- bringing down these will be a challenge and difficult in one pass 🌱 but critical to do so. @robbert115 @CropDoctor54 @agrobaz
In WA there is the toughest-to-kill wild radish. Every year we do offer the most comprehensive test at a very reasonable (lowest) price. If your radish gives you problems send me an email…

Tomorrow there should be a short segment of my interview at ABC either 6.15am or/and 12pm Country hour. Field walk (organised by Boyup Brook Ag Supplies) at Rylington Park next week 14/10

If you start notice some glyphosate resistance in ARG would you:
-still use glyphosate at robust rates + spike,
-switch to Paraquat (new low rates) + spike or
-diversify to glufosinate + spike for knock-down? A trial comparing 33 different spike strategies. Easy poll 👇
No resistance to Sakura + Tref in the ARG samples we tested in 2026.
From 150 annual ryegrass samples, @robbert115 found no resistance to a tank mix of trifluralin and pyroxasulfone.
