LEMKEN Steketee EC-Weeder with DeltaRow is ideal for specialist crops

Steketee hoeing technology is incorporating EC-Weeder for weed-free twin rows and proves its worth combined with DeltaRow in maize crops

This Steketee EC-Weeder was used in testing for mechanical weed control with DeltaRows

Maize grown in twin rows with optimal allocation of growing space is the advantage the LEMKEN Azurit precision seed drill offers with the added benefit of maintaining effective weed control across the full width.

Current weed killing technology from Dutch hoeing technology specialist Steketee called EC-Weeder is an ideal choice for treating DeltaRows effectively.

Steketee is part of the LEMKEN Group and was recently put to the test as part of a master’s thesis supervised by Prof Dr. Bodo Mistele and Prof Dr. Verena Haberlah-Korr at the University of Applied Sciences of South Westphalia in Holland.

Mechanical weed control in maize was performed using a Steketee EC-Weeder equipped with finger hoes and harrows as hoeing tools. Ridging shares were additionally deployed to complete the pass.

Positive effects were confirmed in all variations of the trial. However, the harrow proved to be particularly effective for controlling weeds in the early growth stages, as it rips out and then buries weeds.

With a precisely set Steketee hoe, weeds were very efficiently controlled from the time shoots are just emerging through to the cotyledon leaf stage.

The maize plants withstood the mechanical load well even at the 3-leaf stage, resulting in very low crop losses. Compared to the finger hoe, the harrow had the benefit of also working on a section in between the twin rows.

Ridging around maize plants using ridging shares proved to be a highly effective step in combating larger weeds up to the 5 and 6-leaf stage.

Depending on the operating speed, share width and condition of the soil, efficiencies of 85% and above were achieved as a result.

At the conclusion of the testing it was agreed, when equipped with the right tools, the Steketee EC-Weeder proves to be a highly effective hoeing machine for mechanical weed control in maize, even with DeltaRow twin rows.

The smart camera system ensures reliable control at all stages of growth, as it can be set to twin row mode for young plants or single row mode for the final pass with large plants, depending on crop height.

Conventional farms additionally have the option to combine hoeing between the rows with band spraying in the rows.
