Dry steam weeding

The most economical, effective and eco-friendly pesticide-free solution

machine de desherbage

A method recognised as eco-friendly developed in response to the phasing in of a ban on local authority use of chemical pesticides (France's Labbé Act).
Invasive vegetation is treated using a wand fitted with a cone or nozzle and a detachable ramp.

The machine's triple boiler superheats steam to produce dry steam.
Exposure to dry steam causes plant cells to explode and denatures their proteins, preventing photosynthesis. A few seconds of thermal shock to the plant is enough to damage its metabolism so that it dries out within a matter of days. Find out why dry steam is the best solution.

Warranty: 3 years, except consumable parts 1 year

Application methods:

    1- First year of treatment: 4 treatments (depending on the type of vegetation).

    2- Subsequent years: 3 treatments.

    3- Need for weeding reduces over the years of treatment due to soil depletion.

    4- The first treatment should be carried out after the first shoots appear (February – March).

    5- A final treatment may be needed after the summer seeding period, in areas subject to airborne seed contamination. Long grass should preferably be cut prior to treatment for maximum efficacy.

    6- Applying dry steam (with a very low water content) avoids inadvertent watering of seeds lying dormant in soil, and thus avoids encouraging immediate germination.
