Greenburner is an organic and environmentally efficient method of haulm and green
top desiccation applicable to a range of fruit and vegetable production. It is
also extremely effective in pre-emergence weeding and soil sterilisation prior
to seed drilling. With increasing consumer resistance to the use of acid
and chemicals for burning off green vegetation, there is a need for a better system
that meets modern environmental demands. The Greenburner burns LPG in its
vapour stage at the nozzle, this gives a more direct and controlled flame. This
flame combined with a special heat resistant mesh and Insulation gives the burner
a 2 stage heat effect the first being that of the flame from the burner the second
being the pro-longed infra-red heat given off by the mesh within the canopy of
the Greenburner. In working conditions this flame creates a constant heat of 850°C
under the canopy of the Greenburner, as it passes over the crop. To ensure
optimum performance the Greenburner uses a hydraulically powered air curtain at
the rear of the machine. This provides three functions: - primarily
to prevent heat loss at the rear of the machine,
- to provide an oxygen
supply to the burner nozzles
- ensure an even airflow under the canopy.
The key to the Greenburner's effectiveness is that the
flames from the burners heat an expanded metal mesh under the canopy. This emits
infrared heat at a very high temperature, which rapidly heats the cells of the
vegetation being treated. As a consequence, when the Greenburner passes over the
crop, the cell walls rupture, and this prevents the plant from photosynthesising,
therefore it will wither and die within a matter of hours. The results of
the Greenburner can be seen immediately with the crop turning a different shade
of green as the cell walls break down. The test for whether the crop has been
successfully killed off is the "fingerprint test" i.e. squeeze the plant
between thumb and forefinger, if a fingerprint is left, the weed has been exposed
to enough heat to kill it. After only a few hours the crop begins to die
off and turn brown as shown. The Greenburner is also extremely effective in pre-emergence
weeding prior to seed drilling. For further information on Greenburner
