Reshaping Weed Control for a Healthier Future Webinar – July 20th 3pm CST

Zasso has been invited to join the iSelect Fund webinar:

It’s been nearly 30 years since we discovered a new type of herbicide, and every year the number of chemical-resistant weed strains continues to march higher. Today, there are more than 35 different glyphosate-resistant weed types worldwide, and regulators are increasingly pushing for clean, non-chemical solutions.

Learn how electricity is being used to address this market at “Reshaping Weed Control for a Healthier Future,” a free webinar to be held July 20th at 3PM CST with Dirk Vandenhirtz, CEO of Zasso Group. (Even if you can’t make the live broadcast, registered users will be able to view a recording on our website after the fact.)

Register now.

Zasso Group’s electroherb system can be attached to a conventional tractor, delivering an electrical current below the surface that kills invasive weeds at the root. Unlike other non-chemical herbicides, this system is fast and long-lasting, preventing erosion and allowing for good water infiltration on treated fields.

Self-driving measurement robot for testing soil resistance

To improve our Zasso digital herbicide the team developed a self-driving robot system which can continuously measure the soil resistance. The data are now feed back into the development of the second-generation equipment, to help to improve efficiency. The latest 3 kVA unit is running multiple tests on different plots. With 3 times more energy we can improve average speed and width of the application of the digital herbicide. In parallel we run ecotoxicology tests to proof that the application is not harmful to beneficial organism such as earthworm, bees and ants.



Biological and practical effects of Electroherb on plants

As chemical weed control in cities, on traffic routes and particularly on hard surfaces is practically banned since 2017, currently the only remaining approaches are thermic and me­chanical methods. For all their diversity, both have in common that they hardly ever pene­trate the soil and ultimately only kill off the plant leaves. Their aim is to starve the roots more or less quickly, depending on the plant species, and this way cause die-off. Contrary to the chemical approach, this non-systemic and hardly selective effect demands a relatively high frequency of treatment, particularly if the plants were able to collect solar energy in subterranean organs over a longer period of time which would enable them to regrow.
In contrast, the Electroherb system, tried and tested in Brazil and now introduced in Europe by zasso, offers yet again a systemic approach, by entering the leaves of the plant and then destructively spreading right down into the roots, similar to for example Glyphosate. The difference being that there is no chemistry involved at all, because the Electroherb method employs electric high energy instead.


weed control

Fig. from l. to r.: 1. Dark-green, damaged leaves 5 minutes after treatment. 2. Grass turned brown and dry after 24 hours. 3. Recolonization after eight weeks only in areas where invasive grass can enter. 4. Establishment of herbaceous flowering plants as there is no competition from grass, creating a superior food supply for insects.

The electroweeding process works as follows: If (and only if!) an electric applicator touches a plant, many cells in the leave are already destroyed straight away, like blanching, but with­out a lot of heat; the leaves then initially discolor to dark-green (so-called “wet clothes ef­fect”) and all released cell sap is quickly drying out. At the same time the electrical field de­stroys the electronically charged chlorophyll molecules, which turns the plants yellow-brown. The current spreads through the water and nutrition transport system within the stems and roots and destroys these systems within seconds. As the dried-out plants re­main in place and shades the soil. New plants will have a hard time settling in, just like with chemical herbicide treatment, and depending on soil and climate conditions this will take between 30 and 120 days. If necessary, the plant material can be removed and disposed off mechanically right after extermination. In contrast to chemical treatments this is possible without losing any effectiveness on the root system.
With the energy generated from 1 liter of diesel, around 15 000 to 150 000 plants can be eradicated, depending on their size and the soil conditions.


Ökofeldtage in Frankenhausen (Germany)

Zasso showcased its Electroherb at a German traidfare for the first time

At the first Ökofeldtage in Frankenhausen (21-22 June 2017) many visitors from all over the world were able to get more information about the Electroherb. Almost 10 People non-stop were at our booth and were highly interested in our product.

Furthermore, we were glad to welcome a lot of journalists, who have already mentioned us or will do it within the next days in there highly rated magazines. Alongside these articles, Zasso had its first appearance in German Television and Radio. In the next days we will highlight some articles on our news-page.

Many thanks to the organisers of the Ökofeldtage for the possibility to participate in as an example of Innovation and for the provision of the tractor by Massey Ferguson . See you next year!

European trial time series (Agro-System)

End of  April 2017. Zasso Germany started the first Public European test of the  Electroherb agro-system for digital weeding during the Zasso Day meeting. Before the system was electrically adapted to the European soil conditions which differ significantly from those in southern Brazil.

Instead of using a rear-applicator, we used a full width front-applicator to avoid compaction of weeds prior to Electroherb treatment which would be created by the wheels of the tractor otherwise.
This applicator is height-adjustable on the front three-point powerlift adapting the applicator inclination to areas with different plant height.

Like all other agro-systems, the mechanical energy of the tractor is converted to a high-frequency and high-voltage by a generator and converter unit at the rear and passed through cables to the front applicators. Electric energy is flowing from one applicator through shoot, root and soil to the second applicator passing additional plants and closing the circuit.
Even if April was very rainy and the soil surfaces were very moist, we found one sunny day with dry conditions while air temperature remained still low. The testing area was a hardly cultivated meadow which was mainly grazed by horses. This scenario ensured quite different weeds and types of grasses.
The immediate results were very promising. Even dense grasses became dark green after a few minutes and brownish after 6 hours.
Since the trials were made in Aachen, a city being well-known for rainy days, the weather was often very cloudy, cold and rainy on the days after the application.
Nevertheless, the grass and other weeds became more and more brownish. Sharp edges between treated and untreated areas showed impressively that only touched plants die and other are not harmed.
Time series made over the next weeks showed different modes of drying down. While thistles were already killed by comparatively low energy dosage, other grasses and weeds needed more energy. For some, a 2nd application and adapted applicators will be the next step to maximise the efficiency of the residue free weed killing.For first tests in Europe the results look very promising and further trials both of for agro and urban applications are ongoing.
Just download our Zasso time series here to see all results in Detail.

The Zasso Field Day was a rainy but a successful one.
