Reinert Hopfenflamm

Anwendung ENG


The use of chemical agents to eliminate weeds is becoming increasingly complicated and has been increasingly restricted in recent years. The legislature is planning even greater restrictions, including a complete ban, in all areas in the coming years.

The flame-burning technique offers an interesting and effective way to eliminate weeds, fungi and spores in an environmentally friendly way.



Flaming technology is a practical, economical and environmentally friendly alternative to weed removal. Chemical agents can be completely dispensed with.

The flaming ttechnology does not involve burning plant parts, but rather short-term heating to at least 70 °C. From this temperature range onwards, the cell protein in the plant coagulates. The cell structure is permanently destroyed and a sufficiently large number of cells die.

The plant cells are abruptly heated and killed via heat applied to the plant surface by propane gas burners. The resulting rapid rise in temperature leads to such an expansion of the cell fluid that the cell walls burst. Cell fluid leaks out and the plant dries up.

Propane gas is used because it burns into carbon dioxide and water completely without leaving any residue and in an environmentally neutral way!




Great success.

Before burning, the soil and the surface of the leaf masses should ideally be dry. Basically the following applies: the younger the weeds, the more effective the measure is. Success also depends on the time of use and the weather. This makes a killing success of up to 100% possible.

Our unique high-performance rod burners achieve the highest flame temperature possible with propane gas of approx. 1,925 °C. As a result, all parts of the plant that are directly reached by the operating flame die immediately and with great certainty. The operating flame is generated evenly across the entire width of the burner.

Subsequent rain has no negative impact on the success of a burning measure. This does not affect the effect.

In order to heat all weeds to the required temperatures and achieve sufficient damage, the following rule applies: the higher the exposure temperature, the shorter the exposure time. Lower flame temperatures require a much slower working speed and result in a correspondingly lower effect.

Perfect in time to use.

1. Use

The shoots that have grown back are torched with a burner approx. 2-3 weeks after the first plowing. The infestation of all pests and all fungal spores is also significantly reduced, as they die at temperatures above around 60 °C.

2. Use

Here the Bifang is flamed with a burner approx. 2-3 weeks after the second plowing. The hop vines are also defoliated at the same time using a second, vertical burner.
