Three different modes of action
How exactly do you get the Aclonifen Effect? Find out how three modes of action controls grass-weeds better than any other in our video below.
Power up your pre-emergence application with the Aclonifen effect
Tackling grass-weeds like no other, herbicides Liberator and Proclus work together in one tank mix with three modes of action to protect your winter wheat and barley yield against black-grass, ryegrass, brome and a host of broad leaf weeds. All with the reassurance of a robust herbicide resistance management strategy.

Any weed could develop herbicide resistance but farmers and agronomists can help stop it. Using multiple modes of action in the herbicide programme, is an essential part of long-term product stewardship. A tank mix of Proclus + Liberator contains three modes of action, aclonifen, flufenacet and diflufenican. Aclonifen is unique because it’s the only active substance in HRAC Group 32, flufenacet has been the benchmark active for pre-em control is in group 15 and diflufenican in Group 12. When you apply these three actives together, they target different parts of the plant’s cell to kill the target weed providing better more consistent control.
Liberator + Proclus provides all-round pre-emergence control of grass-weeds and broad-leaved weeds in winter wheat when used in accordance with the following application guidelines:
• Must be applied pre-emergence of the crop, ideally within 48 hours of drilling
• Liberator + Proclus should be applied uniformly to a fine, firm seedbed to form a homogenous layer
• Do not disturb the soil after application of Liberator + Proclus as this will affect the efficacy of the products
• Observe drilling depth requirements on both product labels before application (32 mm of settled soil)
• Apply using a horizontal boom sprayer, in 200-400 litres of water per hectare as a MEDIUM spray (BCPC category)
• Use application rate of 0.6 L/ha Liberator + 1.4 L/ha Proclus in wheat and 0.6/ L/ha Liberator + 1 l/ha Prolus in barley.
Herbicide resistance is genetic process which can occur in any weed population, and means that all active substances are under potential threat. Aclonifen has been classified in a new mode of action group, this doesn’t happen very often, so it’s important to use it responsibly.
Weed control programmes need diverse cultural and chemical control to be sustainable in the long-term. This diversity of control makes the selection pressure more complex, and it’s less likely that resistance will develop. It’s important to not repeatedly use the same modes of action over and over again without other control measures since this will rapidly drive resistance in a weed population.
Aclonifen can only be applied in tank mix with Liberator, at true pre-emergence timing. To support a good resistance management plan ensure any follow-up sprays use herbicides from different HRAC mode of action groups.
Proclus + Liberator is a highly effective pre-em combo for ryegrass control in winter wheat and winter barley. But long-term weed control needs more than just a winning tank-mix. In summer 2021, Bayer worked with NIAB to conduct the largest ever ryegrass survey in UK history. The results underline that ryegrass is a real danger to UK farmers but in most situations, farmers still have the tools to stay in control. Proclus helps protect and sustain the performance of Liberator even when ryegrass is showing signs of resistance.
