    • We are proud to deliver a new mode of action to tackle Australia’s most problematic weeds. And even more proud that we will be the first country to launch this new chemistry - helping to secure the future of farming in Australia.”
      Kristina Hermanson, FMC ANZ Country Manager
    • “Overwatch® Herbicide will be a new tool for growers who are looking for different modes of action to manage resistance, and are looking for different ways to knock down weeds and control them.”
      Tim Obrigawitch, FMC Global Technical Product Manager
    • “Overwatch® Herbicide will be a pretty amazing bit of chemistry, Group Q, a new group, will be a new mode of action into wheat, barley and canola. It is a pre-emergent herbicide, doing a fantastic job equal to the market leaders in ryegrass but also picking up some regionally specific broadleaf weeds as well.”
      Hugh Palmer, FMC Herbicides Product Manager
    • “OOverwatch® Herbicide, proposed as a new group for use as a pre-em for wheat, barley and canola has certainly got the WA agriculture community very excited.  We are widening the battle for ryegrass resistance and the farmers in our patch are very excited about it.”
      Derek Burgess, FMC Western Regional Manager
    • “Ryegrass is a bugger of a weed. Australian producers spend more dollars controlling that particular weed than all other weeds combined. We’re really struggling with ryegrass in our intensive system, resistence is a big issue. So coming out with a new mode of action and a new option is great news for everyone.”
      Stephen Pettenon, FMC Technical Extension Specialist
    • “Overwatch® Herbicide will bring a new mode of action into wheat and barley, in particular, targeting ryegrass and it is demonstrating control of some additional broadleaves, some suppression of wild radish and control of Bifora and other weeds.”
      Tim Obrigawitch, FMC Global Technical Product Manager
    • “The feedback from all the Overwatch® Herbicide trial sites this year is that the weed control just gets better over time. That’s because it is very persistent. Our observations suggest that it will last for about 10 weeks.”
      Stephen Pettenon, FMC Technical Extension Specialist
    • “Ryegrass is a huge problem in wheat and in canola and they’re running out of good options to control it. Overwatch® Herbicide will bring a new mode of action for Australia.”
