In just a few years, Nufarm Crucial has established itself as a leading high-load glyphosate, outperforming the competition. With excellent compatibility and its strong performance on hard-to-kill weeds, it delivers simple, effective control for growers year-round.
Keith Perry, Agronomist at Elders Merredin, first tried Crucial when it came onto the market in 2020 and he’s been recommending it to growers ever since, mostly for pre-cropping knockdown as well as in-canola.
“Crucial is the most robust of the high-load glyphosate formulations that’s out there at the moment. From an agronomist’s perspective, it’s nice to be able to recommend a product that you’ve got confidence in,” said Keith.
“Crucial has some advantages over some of the other glyphosate formulations with some difficult weeds like ryegrass in particular. We just know it’s a robust product and that’s one of the things we like about it.”
Flexible, compatible and easy to use
Beyond its exceptional knockdown performance, Crucial is setting itself apart with an added advantage – versatility. As the most widely registered glyphosate on the market, it can be used year-round, from summer to pre-emergent knockdown, to post-emergent and pre-harvest. It’s also very easy to use and mix, with excellent compatibility and no need for additional surfactants.
“One thing that I really do like about Crucial is the compatibility in comparison to some of the other products that are out there, the high-load glyphosates in particular,” said Keith.
“Here, it’s very common to mix it with trifluralin. It’s pretty common to use it with the likes of 2,4-D ester as a knockdown pre-crop and some of the Group G products like Terrad’or. All those Group Gs and things like atrazine, simazine and diuron – it mixes well with all of those.”
A game-changer for canola growers
Thanks to its registration package, Crucial allows growers to simplify and streamline their glyphosate program, with a lot of benefits in particular for canola growers. Crucial is registered for key glyphosate-tolerant canola varieties – Roundup Ready, Optimum GLY and TruFlex – so it delivers fast, effective control all the way from pre-emergent to pre-harvest. That means canola growers can move away from complex programs, with no need to switch between different formulations and surfactant packages.
“The fact we’ve got registrations for use in TruFlex and … the Opti-Gly canola now as well is a big advantage,” said Keith.
“We’ve also been using Crucial most years for pre-harvest desiccation.”
The best of both worlds
For Keith and his growers, the results speak for themselves.
Crucial is a big step forward from the complex programs of the past – no more switching between different formulations and glyphosates throughout the year. With fast control and greater flexibility than other glyphosate formulations, it offers growers the best of both worlds.
