Why Mix It Up?

The management of weeds is the greatest challenge broadacre Australian farmers face, with an annual cost to growers of $146/ha or $3.3bn.1
This challenge increases dramatically if weed populations become resistant to herbicides, as the use of properly applied herbicides at label rates is the most consistent, effective and economical approach to control weeds.

Herbicide resistant weeds reduce profitability and choice of herbicide control options, and are a challenge on a local, national and global level. Utilising integrated weed management (IWM) approaches and mixing it up will help prevent and delay resistance on your farm.
Use the free Resistance Tracker to learn more about weed resistance in your area. Enter your postcode and pin point exactly which weeds you should be on the lookout for. 
Understand herbicide modes of action and find out which weeds have developed resistance to specific MOAs. 
259 different weeds have developed resistance in 93 crops.

Mix It Up – ‘Resistance Tracker’ from Bayer

'Mix It Up’ is dedicated to helping farmers and advisors manage herbicide resistance in Australia. 
19 weed species display resistance, info by Bayer Crop Science.

Annual ryegrass is Australia’s most costly herbicide resistant weed, with alternate control measures and poor control costing growers more than the sum of all other resistant weeds.1

Resistant ryegrass has been found in paddocks around at least;
        69 WA towns
        62 SA towns
        66 VIC towns
        43 NSW towns2
