With the ban on glyphosate-based herbicides since 2019, many amateur and professional gardeners are turning to more environmentally friendly alternatives. Natural weed killers have become a popular solution for keeping gardens clean while preserving our health and that of the planet.
Advantages of Natural Weed Killers
Environmentally Friendly
Unlike chemical products, natural weed killers do not pollute the soil or groundwater. They preserve biodiversity and contribute to a healthier ecosystem. Many recipes use ingredients found in the kitchen or easy to obtain, eliminating the need for plastic packaging and reducing the carbon footprint.
Safe for Human Health
Chemical herbicides can have serious health consequences, including increased risks of cancers and other chronic diseases. By opting for natural solutions, we avoid these dangers while ensuring the food safety of vegetable crops.
Main Methods of Natural Weed Control
Vinegar Solution
The use of white vinegar is one of the most common methods to combat weeds. Mixed with water, sometimes added with salt and liquid soap, this homemade weed killer is effective and easy to prepare.
- 200 ml of white vinegar
- 200 ml of water
- 1 tablespoon of salt (optional)
- A few drops of liquid soap (optional)
This solution should be sprayed directly on the weeds on a sunny day to maximize its effectiveness.
Boiling Water
A simple but often overlooked method is the use of boiling water. By pouring very hot water directly on unwanted plants, a thermal shock is caused that destroys their cells. This works particularly well for weeds growing between slabs or on paved pathways.
Baking Soda
Baking soda has drying properties that can be used to kill certain weeds. Simply sprinkle some baking soda on the damp leaves of the plants to be eliminated.
Innovative Agricultural Practices
Mechanical Weeding
Many farmers adopt mechanical techniques to weed their fields. For example, the use of hoes, weeders, or harrows helps keep weeds under control without resorting to chemical products.
Use of Animals
In France, some farms introduce animals like ducks into rice fields to combat weeds. These ducklings eat weeds without touching the rice, offering a sustainable and biological solution.
Socio-Economic Impacts
Cost Reduction
Natural weed killers can significantly reduce costs compared to commercial products. By using common household ingredients, gardeners save on repeated purchases of expensive chemicals.
Creation of Local Jobs
Adopting natural and local practices can also encourage the creation of jobs at the local level. Initiatives for the development of organic and eco-friendly products stimulate employment in the agricultural and gardening sector.
Research and Development
Ongoing Innovations
Agricultural research continues to explore new avenues to improve the effectiveness of natural weed killers. Scientists are working on formulations based on essential oils, specific composts, and mineral blends to offer increasingly effective and environmentally friendly solutions.
Public-Private Partnerships
Many collaborative projects are emerging, involving both public institutions and private companies. These partnerships promote innovation and allow for a broader dissemination of ecological solutions.
