The 2025 Australian turf herbicide resistance chart shows herbicide mode of action (MOA) groups. This includes the sulfonylureas, and pre emergent herbicides. The new chart now includes Pylex and Poacure which are two recent additions to the weed control arsenal.
You can use this free herbicide resistance chart along with our other free management tools for turf managers.
- Turf fungicide resistance chart.
- Turf insecticide resistance Chart.
- Weed ID chart and
- The free Guide to turf chemicals. This herbicide chart also shows herbicide sites of action to better help turf managers delay the development of resistance.
There is also an example of a pre-emergent and post emergent strategy to manage this. For example granular pre emergent herbicides will come under Groups 3, 14 and 15.
The Monument herbicide alternative, Recondo herbicide is a class 2 herbicide. Duke herbicide is also in this herbicide group.
As we discuss in factors that affect herbicide performance, herbicide resistance in turf is a plant’s inherited ability to survive a herbicide application that kills a weed. It results in poor herbicide results, as resistant weeds survive herbicide application at rates much greater than the label rate.
In Australia, over 25 weed species have populations that are resistant to at least one herbicide MOA group. In turf grass, world-wide this is becoming an increasing issue, with over 40 reports as of 2019.
This means free guides like this herbicide group chart are important tools to get the best long-term results from your herbicides.

Graduated from Newcastle University with an Hons Degree in Soil Science in 1988, Jerry then worked for the Sports Turf Research Institute (STRI) as a turf agronomist before emigrating to Australia in 1993.
He followed this by gaining a Grad Dip in Business Management from UTS. He has worked in a number of management roles for companies as diverse as Samsung Australia, Arthur Yates and Paton Fertilizers.
He has always had a strong affinity with the Australian sports turf industry and as a result he established Gilba Solutions as an independent sports turf consultancy in 1993. Jerry has written over 100 articles and two books on a wide range of topics such as Turf Pesticides and Nutrition which have been published in Australia and overseas.
