Comparison Of Electroherb With Other Methods

Trials and results from Brazil and the level of knowledge for Europe

The zasso system for electrophysical weeding was originally developed in Brazil and is presently used there effectively on a wide range of application areas. The success of the method, especially in comparison to Manual weeding and glyphosate spraying, was proved for several crops. Most of these tests were performed as pragmatic “on the farm” or “on the road” trials. In the majority of cases efficacy studies were not made by scientific data evaluation; instead the success was defined by the customers who have been booking the Electroherb service over many years, for their agricultural, silvicultural and urban applications. A general, strong trend visible in the results is that Electroherb has huge advantages over any kind of manual weeding or spraying. Costs of Electroherb are very comparable to mechanised spraying, but Electroherb does not need herbicides. Data for and descriptions of These studies are available from zasso.

There are up to now no larger data sets on a sound scientific testing basis that would allow detailed comparisons between various non-chemical methods (meaning mechanic or thermal weeding), especially not for European climate conditions.

For this reason, zasso is planning a larger number of well-documented test trials with a wide range of partners from agriculture, urban weeding and forestry for the 2017 season. This will include efficacy testing towards selected weeds in specific environments as well as comparisons between different chemical and non-chemical treatment methods. Tests in standardized environments, just like for chemical herbicides, are under development, as well as studies in potential ecotoxicological side effects and a more differentiated insight into the mode of action of Electroherb Systems.

It has already become clear that Electroherb acts right down to the roots and this way is able to reach significantly more reproductive tissues than by just killing the shoots above soil level. Therefore, the effects will be more systemic – damaging photosynthetic and vascular weed tissues – and less a mere starving of the plant. Regrowing weeds will be forced to mobilize their root energy resources. For weeding the energy needs in the range of 5 to 15 litre diesel per hectare and a first approximation of 300 Joule per 15 centimeter plant also suggest a high energy efficiency, particularly as such amounts of electric energy don’t heat up the plants in any relevant way.
