We're the Australian Herbicide Resistance Initiative (AHRI), a research team based at UWA with investment from @theGRDC. More crop, fewer weeds - sustainably!

[AHRI @AHRI_Team]

Resistance can emerge after just 4–6 herbicide applications. The AHRI team continue to deliver updates on resistance levels using randomized survey populations to assess herbicide response across fields. #HerbicideResistance #Agriculture

[AHRI @AHRI_Team]

Visiting @thegrdc scholar @MartinVilaAiub is working with AHRI to evaluate the competitiveness of Aus. wheat cultivars versus weeds. Results will pinpoint which wheat traits most effectively outcompete weeds. #wheat #agriculture

[AHRI @AHRI_Team]

AHRI PhD @6LukLam (@UWAnews @WAAgCollab @thegrdc) leverages satellite imagery to mask in-field objects and will combine drone data to predict weed pressure. Luk aims to produce low-cost weed maps to enhance broad-acre crop management. #AgTech #PrecisionAg

[AHRI @AHRI_Team]

AHRI researcher @wkramer196 has begun testing glufosinate with various group 14 PPO herbicides to identify the best mix to control glyphosate resistant annual ryegrass across WA. Trials will measure visual injury and synergism between the two herbicides. #weedscience

[AHRI @AHRI_Team]

AHRI welcomes research scholar Dr Huanhuan Wang to the @theGRDC Next Generation for Weed Management project. She’ll analyse weed-mapping data to validate a novel prediction model that supports detection and site-specific weed control. #WeedScience #WeedManagement

[AHRI @AHRI_Team]

AHRI & @cwssuwa team collaborate on a number of @thegrdc invested projects. Thank you CWSS for a productive and enjoyable networking event.

[AHRI @AHRI_Team]

We continue to build on our knowledge of herbicide resistance. https://t.co/wphjWJPJUT

Wild radish appears better controlled by either glufosinate or glyphosate applied as stand-alone. Mild antagonism observed with the tank mix.

[AHRI @AHRI_Team]

We’re excited to welcome PhD student Ayesha Farooq to AHRI at UWA. Ayesha will investigate diflufenican resistance in wild radish, integrating molecular biology, herbicide physiology and genomics to unravel both target-site and non-target-site resistance. #HerbicideResistance

[AHRI @AHRI_Team]

AHRI post-grad Rob Lujan-Rocha is investigating a novel approach for scalable weed prediction and mapping to enable integrated weed management in Western Australian cropping systems.

From professional soccer overseas to agricultural research in WA ⚽🌾

WAARC Postgraduate Scholarship participant Roberto Lujan Rocha spoke with Kate Forrester on ABC’s Great Southern & South West Rural Report after our Confidence in Communication Workshop.

[AHRI @AHRI_Team]

In May, the AHRI team began growing out randomly collected weed seed survey samples. This @theGRDC investment continue to deliver herbicide‑resistance incidence and trends in WA grain paddocks. #HerbicideResistance

[AHRI @AHRI_Team]

AHRI technician Shane Baxter has collected 500+ soil samples from the WA grain belt to measure the weed seed bank. Follow-up trials will test how plant competition and different herbicide rates influence weed vigour. #WeedScience #AgResearch

[AHRI @AHRI_Team]

Are you calling the shots on sowing date, rather than letting the weeds take control? University of Adelaide's researcher, Gurjeet Gill delves into the ideal timing for sowing winter crops! 🌾 #CropManagement #AgScience#Agronomy

We're thrilled to welcome Dr William Kramer to the @AHRI_team! In this @TheGRDC supported role, Dr. Kramer will evaluate the effectiveness of MOA herbicide combinations & study multi-resistant weed profiles. #HerbicideTech #AgResearch @wkramer196

[AHRI @AHRI_Team]

Evaluate the long-term cropping profitability of strategic and tactical weed control methods on farm. https://t.co/lbsDgH1Hw5

[GRDC @theGRDC]

Summer weed control delivers one of the strongest returns in cropping.

GRDC-invested research shows $3–$8/ha return for every $1 spent, through better soil moisture, N and disease control. Timing is key.

[AHRI @AHRI_Team]

Test, test baby! 🎶 AHRI studies have shown resistance frequency to stand-alone pre-emergence herbicides ranged from 10% to 34%, yet resistance to herbicide mixtures ranged from 0% to 6%. #herbicidemixes https://t.co/2jHixnQKDR

[AHRI @AHRI_Team]

AHRI PhD candidate Luk Lam delivers a great summary on his research.

[GRDC @theGRDC]

Mapping problem weeds like ryegrass, barley grass, brome grass and wild oats at scale remains a challenge.

PhD candidate Luke Lam (@UWAnews) is using satellite and joint imagery to develop low-cost weed mapping tools for WA canola, wheat and barley systems. Part of GRDC's #WeedManagementInitiative.

[GRDC @theGRDC]

Remote sensing and spot spraying promise big herbicide savings, but only if we can reliably tell weeds from crops.

PhD candidate Roberto Lujan Rocha (@uwanews) is tackling one of the biggest barriers to making this tech scalable and affordable on-farm.
