Australia’s smashing it on the wheat front — or so the headlines say.
According to a recent Reuters article, Aussie farmers have pulled off something of a miracle: higher wheat yields, better water efficiency, and booming exports — all while dealing with hotter, drier weather. Pretty impressive. But as always, we like to ask: what’s missing from the story?
Because while the spotlight’s been on smart breeding and high-tech tractors, there’s a quiet supporting act that rarely makes the headlines: glyphosate. And if we’re being honest, it might be doing more of the heavy lifting than anyone wants to admit.
What’s Really Behind the Wheat Boom?
Here’s what the article tells us:
- Aussie farmers now grow 15 million more tonnes of wheat each year than they did in the 1980s.
- They’ve nearly tripled the amount of wheat grown per drop of rain.
- And they’ve done it all with very little government subsidy.
It’s a good story. A great one, actually — if you leave glyphosate-based weedkillers such as Roundup out of it. But we can’t.
Let’s Talk Glyphosate
Since the late ’80s, glyphosate has become the farmer’s best friend. Not just for killing weeds, but for drying crops like wheat right before harvest — a practice called pre-harvest desiccation. It makes harvesting easier, faster, and more uniform. In a dry continent like Australia, where timing is everything, that’s a big deal.
And most of the time, that glyphosate comes in the form of Roundup — a product so entrenched in industrial farming it’s almost invisible.
The Flip Side of Efficiency
Here’s the thing about leaning too hard on one chemical: it doesn’t stay effective forever.
- Weeds fight back. Glyphosate-resistant superweeds are already causing headaches.
- Soil health suffers. There’s growing concern about what repeated glyphosate use — particularly from Roundup — does to the tiny ecosystems under our feet.
- Residues end up in the food. And some of Australia’s biggest export partners — like Japan — are watching closely.
Efficiency is great. But at what cost?
A Tale of Two Trends
Reuters points out that while Aussie yields are climbing, other countries like the US, Canada, and much of Europe have hit a plateau. One possible reason? Tighter glyphosate regulations. More restrictions, more scrutiny, and in some places, outright bans.
In some cases, those restrictions have specifically targeted Roundup and similar commercial formulations — which often contain surfactants and additives that may pose additional risks.
So we’re left wondering: is Australia’s success a sign of superior farming — or just delayed consequences?
Innovation or Chemical Shortcut?
This is where the conversation gets uncomfortable. The article paints a picture of market-driven brilliance. But if much of that brilliance comes from routine glyphosate use — a method now under fire around the world — is it really innovation? Or just the path of least resistance?
And when that use largely relies on one product — Roundup — it raises serious questions about resilience, independence, and long-term sustainability.
Sustainable agriculture experts have long called for a rethink: crop rotation, integrated weed management, and smarter systems that don’t rely on one chemical to hold the whole thing together. Because when that crutch gets kicked out, what’s left?
Time to Ask Better Questions
Australia’s farming gains are real — but so are the questions they raise. Are we confusing short-term productivity with long-term sustainability? Is it innovation if it can’t last? And most importantly — what happens when glyphosate is no longer an option?
Because progress isn’t just about growing more wheat. It’s about doing it in a way that won’t come back to bite us.

Maize yield stability under organic and conventional farming systems in sub-humid agro-ecozones of Central Kenya
European Journal of Agronomy (2025)
A 15-year study (2007–2022) comparing organic and conventional maize systems in Kenya’s sub-humid agro-ecozones. While conventional systems initially outperformed, organic yields gradually caught up — and in lower-fertility sites, organic systems showed greater yield stability. Highlights how organic methods can provide long-term resilience without heavy chemical inputs like glyphosate.

Organic plots, which avoid glyphosate and other synthetic herbicides, build healthier soil, improve water infiltration, match conventional yields (and outperform under drought), and offer more resilience and profitability over time.
