Proclus
Proclus is an exciting step forward for pre-emergence control of black-grass in winter wheat and winter barley.
Product details
The pre-emergence timing is absolutely essential for effective black-grass control. Adding Proclus to Liberator provides a valuable improvement in control.
At the pre-em timing, it is common to tank-mix two or more products. This season (2020/21) Proclus is an additional and effective tank mix partner but in future seasons, Bayer expect to have a three-way co-formulation of aclonifen, flufenacet and diflufenican available. This will give farmers a highly effective pre-em herbicide in one can, easy to plan and easy to use.
The first season is an opportunity for farmers and agronomists to start using aclonifen and learn about the active before the co-formulated products become available.
Another attractive feature of Proclus is that it is a different mode of action to other common cereal grass weed herbicides and it has a low resistance risk. As a result, it is an important addition to ensure the long-term activity of flufenacet.
Proclus is only to be used at the pre-emergence timing with Liberator. Follow the same guidance as Liberator applications at the true pre-emergence timing. Apply within 48 hours of drilling to a fine, consolidated seedbed free of trash or clods. Aclonifen is not as dependent on soil moisture as the flufenacet in Liberator so there is potentially a little more flexibility to use in dry conditions. However, the best results still come when applications are made with a little soil moisture around.
Before using Proclus to boost pre-emergence performance, make sure that all the correct cultural controls are in place to manage grass weeds. Delaying drilling into the second half of October and reducing depth of cultivation and level of soil disturbance at drilling are all important steps to prevent black-grass.
Delaying into October, also ensures soil moisture for flufenacet efficacy and means that residual protection extends into winter and may help contribute to winter kill of weeds if conditions are right.
10-15% improved black-grass control over straight Liberator.
Only available as part of a co-pack with Liberator to be mixed on farm.
3-way co-formulated product with aclonifen, flufenacet and diflufenican expected next season.
Pre-em usage only for Proclus + Liberator mixes.
Approved for winter wheat crops only
