Reinert Hopfenflamm

Anwendung ENG

Without herbicides

The use of chemicals for the removal of weeds is getting more and more complicated and has been increasingly limited for several years. In the coming years, the legislature is planning an even stronger restriction up to a complete ban.

The flame weeding technology offers an interesting and effective way to weeds, spores and moulds in an environmentally friendly way.

We have been accompanying the first trials at hop cultivation with our proven equipment technology since 2007

Based on the experience we have gained since then, we have developed and  continuously improved an appropriate mounted flame weeding device for the hop production over the past few years

The result of this development is now our special equipment hopfenFLAMM 2450.


operating principle

The flame weeding technology is a practical, economical and environmental alternative in the weed removal.

There is absolutely no need of any chemical agents.

The flame weeding technology is no burning of plant parts, but a short-time heating up to at least 70 °C. From this temperature range, the cell protein coagulates in the plant and the cell structure is thus permanently destroyed.

The result is the death of a sufficiently large enough number of cells.

The plant cells are abruptly heated and killed by the heat applied to the plant surface by a propane gas burner

The resulting rapid rise in temperature leads to the bursting of the cell walls due to the strong expansion of the cell fluid.

Cell fluid escapes and the plant dries out.

Cell protein coagulates by warming up with around 70 °C.


Propane gas is used, because it burns completely residue-free and environmentally neutral to  carbon dioxide and water!





Before a flaming measure, the soil and the surface of the leaf masses should ideally be dry.  

The following generally applies: the younger the wild herbs are, the more effective the measure is. The success also depends on the application time and the weather. This enables a killing success of up to 100%

Due to our unique burner technology there can be produced the maximum possible temperatures of 1.925°C with propane gas.

As a result, all plant parts that are directly hit by the flame, die immediately and very reliably.

The operating flame is generated equally over the entire width of the burner.

Subsequent rain has no negative effects on the success of a flaming measure.

In order to heat all wild herbs to the required temperatures and to achieve sufficient damage, the following rule applies: the higher the reaction temperature, the shorter is the reaction time. Lower flame temperatures require a much slower working speed and have a correspondingly lower effect.






APPLication time

1st Application

Regrown shoots are flamed with a burner approx. 2-3 weeks after the first hilling.

This also significantly reduces the infestation with all kind of fungal spores, as they die off at temperatures above approx. 60 ° C.

2nd Application

About 2–3 weeks after the second hilling, only the row is flamed. With a second, vertical burner, the hop plants are also defoliated at the same time.
