Nufarm’s CRUCIAL was more effective on the strong resistant ryegrass biotype

The combination of glyphosate salts and surfactant systems have a dramatic effect on how a glyphosate formulation performs in the field.

Weed control differences between formulations can be observed when they are applied under less than ideal conditions, such as stressed weeds or weeds that are developing herbicide resistance.

Having a product we can trust across such a wide variety of uses also makes it really simple for our growers.

We haven’t seen anything else that’s this fast and effective and that we can use across different so many different growing scenarios, with no worries about safety or crop damage.

There’s nothing else like it on the market, especially in the pre-emergent knockdown space.
