Electricides, or the use of electricity to kill weeds, is swiftly becoming the best viable alternative for traditional methods of weed control in modern agriculture. This is largely due to its low environmental impact, sustainability of use, and the inability of weeds to develop resistance to voltage. Therefore, electric weeding programs or the use of an electric weeder will be particularly attractive to organic or environmentally conscientious farmers. In this blog, we will explore the beginnings of the electrical weed control revolution and Old School Manufacturing’s part in helping the electricide industry become the sustainable, effective practice it is today.
Electrical weed control is a form of mechanical weed removal, which is the use of specialized machinery to eliminate weeds. More specifically, it is a form of thermal or electrothermal weeding, which is the use of heat or cold to kill weeds. This category includes weed control methods like microwave technology, solarization, steam, and flame weeding.
While electrical weed control was experimented with at the end of the 19th century, particularly by railroad companies, it was not until the 1970s-1980s that the first commercial electric weeder was released. This was the Electrical Discharge System, marketed by Lasco as the Lightning Weeder, which had a PTO-driven generator and transformer. The Lightning Weeder was developed with both a front and rear-mounted boom, with later versions favoring a rear-mounted boom.
The release of the EDS by Lasco led to many new experiments with the technology; the most notable of these being done by Dr. Michael Diprose. Dr. Diprose’s early experiments with the Lasco Lightning Weeder are at the forefront of using electricity to kill weeds, forming the basis of the machine his company RootWave produces.
One of the greatest strengths of the RootWave machines is that they operate at a higher frequency, allowing operators greater control over the phenomenon of power sharing. Power sharing occurs when electricity is conducted through a plant that has already been shocked, causing less damage to new weeds.
Higher frequencies are also considered safer, as shocks from higher frequencies are more likely to result in burns, whereas shocks from lower frequencies are more likely to cause cardiac arrest. These discoveries were all made possible by Dr. Diprose’s experiments with the Lasco Lightning Weeder, a machine that utilized lower frequencies.
The early days of electric weed control faced significant challenges, particularly in power supply and effectiveness across various weed species. Initial systems struggled with consistent power delivery, often leading to incomplete weed kills and varying effectiveness across different weed morphologies. These limitations, combined with the rise of chemical herbicides in the mid-20th century, slowed the adoption of electric weeding. However, as herbicide resistance became more widespread, the agricultural community began revisiting electric weed control methods as a viable alternative to chemical herbicides.
The 1970s saw the introduction of higher voltage systems, leading to the emergence of more advanced electric weeders. One notable example is the Weed Zapper, which was used extensively in row crops like soybeans and sugar beets. These early systems laid the groundwork for future innovations in electric weed control, demonstrating the potential of electrical current to manage weeds in large-scale agricultural settings.
The early 2000s brought significant innovations in electrode design and the use of electrical current for more targeted weed management. High-voltage transformers allowed for greater precision in weed control, making electric weeding more effective and adaptable to various cropping systems. These advancements paved the way for the resurgence of electric weed control as a practical, cost-effective method of weed management.
In the past decade, other companies have played pivotal roles in promoting electric weeding as a viable alternative to chemical herbicides. The technology has seen global expansion, particularly in markets like Europe, Australia, and Canada, where it has gained acceptance among growers and agronomists alike. The adoption of electric weeders in these regions highlights the growing recognition of electric weeding as a sustainable and effective weed control method.
Old School Manufacturing has been at the forefront of developing and refining electric weeding technology. The company’s innovations, particularly in electrical power distribution and electrode design, have set it apart in the industry. By focusing on the efficiency and effectiveness of electric weeders, Old School Manufacturing has made significant contributions to the evolution of electric weed control technologies.
The innovations introduced by Old School Manufacturing have made electric weeding a more cost-effective and efficient weed control method. When compared to traditional methods like mowing and tillage, electric weeding offers a sustainable and economically viable alternative. The company’s advancements have reduced the overall cost of electric weed control, making it more accessible to a broader range of growers.
The future of electric weeding lies in continued innovation and integration with other weed management practices. Combining electric weed control with methods like mulch and tillage could offer a holistic approach to sustainable weed management. Advances in technology, such as the development of more efficient transformers and electrodes, will further enhance the effectiveness of electric weeding.
As the global agricultural community continues to seek sustainable alternatives to chemical herbicides, electric weeding is poised for expansion in regions like Australia and Europe. However, challenges remain, such as adapting the technology to different weed morphologies and cropping systems. Addressing these challenges will be crucial for the widespread adoption of electric weeding.
Electric weeding’s long-term benefits are clear: it offers a sustainable solution to weed management that reduces reliance on chemical herbicides and promotes environmental stewardship. As the technology continues to evolve, its role in global agriculture will likely grow, contributing to more sustainable and resilient farming practices worldwide.
The evolution of electric weeding technology, from its early days to its current status as a viable alternative to chemical herbicides, has been marked by significant milestones. Old School Manufacturing has played a crucial role in this journey, contributing key innovations that have shaped the industry.
