Using Roundup pre-plant

Giving the cleanest start to your OSR

When it comes to OSR traits, DEKALB hybrids have the proven ability to establish robust, well-rooted OSR plants that are best able to cope with challenging conditions. When it is about weed control, Roundup has the proven ability to achieve long-term control of common weeds that complicate OSR emergence and establishment. The combination of both: first, the pre-plant treatment with Roundup, followed by the seeding of DEKALB hybrids offers the best opportunity to get the timeliest OSR off to the cleanest possible start.

To achieve a uniform emergence and even stand of oilseed rape, the soil must be fine and as weed-free as possible when planting and during the crop’s early development. The pre-plant treatment with Roundup offers a great opportunity for preparing the desired seedbed, eradicating perennial weeds and reducing the population of the annual weeds. Ultimately, it contributes significantly to the successful emergence of the OSR crop. Learn more about the main benefits of Roundup pre-plant application before OSR seeding, usage recommendations and the best DK hybrids for a successful OSR emergence.


Benefit 1: Successful OSR emergence

The pre-plant treatment with Roundup enables a faster and more even emergence of the crop and better crop establishment due to no or little weed competition and better soil structure.



Benefit 2: Effective weed control in OSR

The pre-plant treatment with Roundup is a great opportunity to achieve the optimal control of annual and perennial weeds that can affect OSR establishment.

By replacing mechanical weeding, the pre-plant treatment helps to preserve the soil moisture and organic matter content. Every tillage operation evaporates 3-5 mm rain equivalent moisture.

It also contributes to higher selective herbicide efficacy when combined with tillage.




Benefit 3: Short cultivation interval

Seedbed preparation or seeding can start 2-3 days after the Roundup pre-plant treatment without loss of efficacy

Faster than mechanical weed control – saves time in the busy summer period.
