How weeds became illegal

Where weed killers are forbidden

Weeds feel particularly at home where flowers and grasses grow. Because weeding is too troublesome for them, many hobby gardeners use weed killers. But these are by no means allowed everywhere and are not always useful.

What many do not know: The Plant Protection Act only allows approved weed killers to be used on areas that are used for agricultural, forestry or horticultural purposes.

Weed killers like glyphosate are taboo on pavement and paths

In general, pesticides must not be used on sealed surfaces such as sidewalks, paved driveways or terraces - regardless of how much wild growth is growing in the joints. Violations of the Plant Protection Act can be punished with fines of up to 50,000 euros.

Recently, the debate about the approval of the weed killer glyphosate has made headlines. Many a hobby gardener may have been irritated by all the back and forth. However, regardless of its general approval as a plant protection product, the use of glyphosate on sealed surfaces remains prohibited.

Because the pesticides could get into our drinking water with the runoff surface water via the sewer system, explains the consumer information service aid. "In crop stands, the active ingredient is broken down after the waiting period has been observed if everything is handled correctly from a technical point of view."

Alternatives to the chemical club

To kill weeds on pavement and paths, you have to forego the use of the chemical club. But working with the joint scraper is tedious and time-consuming. A simpler method is to scarf the weeds with the weed burner.

"This has the advantage that all residues are burned and a clean appearance is created. In addition, the joints are spared, as no filler material is pulled out with the roots," explains aid.

Use plant protection products correctly

Even where they are allowed to be used, pesticides are not always useful. Because neighboring crops can also suffer. For example, nettles, ground elder and bindweed can often be found next to ornamental trees. When using chemical weed killers, there is a high risk that they too will be damaged.

Often the agents can therefore only be applied with a spray hood and in a very targeted manner. It is mandatory to observe such instructions for use. But often weeds and ornamental plants have mixed up so much that they can hardly be treated individually. Then it is better to do without the use of pesticides.
