City without pesticides, things are happening

Pesticides are often used in cities and communities to keep playgrounds, sports fields and roads free of grass and weeds. These pesticides then enter the waterways or the wastewater treatment plant, but there are alternatives, such as nature itself.

An alternative to getting by without toxic pesticides is to take wild herb growth into account when planning sealed areas. Insects die from pesticides. In addition, they are harmful to health. They are detectable in groundwater and urine. The term pesticides is a collective term that includes biocides and plant protection products. Herbicides are used to keep squares and driveways free from weeds. Fungicides and insecticides are used in beds and green areas to control pests. Biocides are chemical agents. Among other things, they are used to fight rodents, to disinfect drinking water and to paint facades. They are designed to reduce mice, algae and insects.

Instead of pesticides, weeds can be used for thermal or mechanical regulation. For example, weed brushes can be used for surfaces with paving stones. Another possibility is the steam processing of hot water. The green spaces and flower beds are maintained with manual weeder, hoes and mowers. Another method is flamboyant. However, this method is bad for the climate because it consumes a lot of energy. The amount of work can be reduced by creating flowering lawns and native perennials in place of short-grass areas that need to be constantly cared for. With flowering meadows and native perennials, the amount of work is reduced. The boxwood and the oak processionary are very aggressive insects. To combat this, biological agents are used as far as possible, such as neem oil or preparations containing Bacillulus thuringiensis. There are also invasive species such as the Japanese knotweed. If fewer pesticides are used, more plants can spread again. This increases the quality of life. If you need some relaxation after a hard day at work, you will find everything here. Plants bind the fine particles, remove CO2 from the air and release the precious oxygen again. This creates a good climate. The plants also attract insects such as butterflies, bumblebees, bees, and birds. This increases your food spectrum.

Plants come first, animals later. This is how biological diversity increases again. Plants that have a high degree of coverage are best suited. For example, different types of perennials can be planted together in groups. Unwanted weed growth is suppressed naturally. Also, the surfaces don’t have to be maintained as often. If you use plants with a high degree of coverage, this brings even more advantages for the summer. Soil water cannot evaporate that quickly. The heated air of the city can get cold due to the moist soil. Since the soil is wetter, the water can be absorbed better in heavy rains. Open and arid soils are unable to absorb rainwater. In the worst case, this can lead to flooding.

Protect nature in the best possible way

Tufted grass is another alternative to pesticides. It requires relatively little maintenance, is easy to use, and looks great too. Schottenrasen is a combination of compost, gravel and special herbs and herbs. It offers almost the same benefits as a conventional lawn. But its maintenance is less expensive. It also has better water absorption when heavy rain occurs. This minimizes the risk of flooding. During the summer, the water that has infiltrated the ground evaporates and the city air cools.

Flaming or infrared use is mainly used for gravel and gravel. There are companies that offer special techniques in this regard, such as flame-flame devices or infrared devices. They work with steam, hot foam or water. In the long run, this means that it is possible to save staff and reduce the cost of care.

Step by step towards pesticide-free cities

The ban on the use of pesticides on public land should be adopted in the first place to improve nature again. The goal is spontaneous vegetation where possible.

The second step should be to plan how paths, streets, flower beds, squares and other green spaces can be optimally arranged. Care must also be taken to ensure that maintenance is kept to a minimum. Close to nature means with nature and for nature. Components include water permeable areas, smooth transitions, lean substrate and native perennials. Pesticides should only be used when there are absolutely no other options. There are towns and villages where it is not allowed to create spontaneous vegetation. This has to do with security, among other things.

The alternative to chemical pesticides should therefore be thermal or mechanical methods of weed removal. If native plants are used, care is not that complex. This can be the wildflower meadow, which should not be mowed more than twice a year, or the wild perennial bed. This just needs a little maintenance from time to time. Another option is a native hedge that rarely needs boxwood pruning. Trees improve the urban climate. Pollutants are filtered out of the air. They provide nesting sites for bats and birds, provide shelter and food, and insects settle there. The tree species must be the right one for the site, as it will be exposed to high levels of pollution and salinity, as well as extreme heat and drought.
