Plant protection products are pesticides.


Plant protection products

Plant protection products can be harmful to health and the environment and only a few are approved for private use. You can prevent pest/weed problems in your garden by, for example, choosing pest-resistant plants, cultivating the soil and using weed control fabrics.

Plant protection products are pesticides and are used to protect plants and crops against various kinds of weeds and pests.

Only a few plant protection products are approved for private use in Swedish gardens. Most agents are used to prevent moss and weeds. Controlling moss by applying chemicals often needs to be repeated, and therefore large amounts of these agents are generally used. For those who want to cultivate plants organically, there are several biological plant protection products that work well in gardens and greenhouses.

Here is how you can protect your garden from fungal and insect infestations without using chemical plant protection products:

  • choose pest-resistant plants
  • cultivate the soil
  • use weed control fabrics
  • use adhesive traps (sticky traps)
  • shower plants with water to get rid of aphids, for example
  • use weeding tools to eliminate weeds
  • drain the garden
  • fertilise
  • prune trees and shrubs.

If you need to use a plant protection product, it must be approved by the Swedish Chemicals Agency. Approved plant protection products always have a four-digit registration number and are divided into three authorisation classes. Products marked Class 3 may be used by the general public. In the Pesticides Register (in Swedish only) External link. available from the Swedish Chemicals Agency, you can check the registration number and see if the product is approved, what class it belongs to and find other important information.

Look for the warning label on the plant protection product’s packaging and read the information provided so that you know how to handle the product safely.

If you buy a plant protection product on the internet, you always have the right to receive all hazard information about the product before you make the purchase. Keep in mind that other countries may have other regulations, but any agents that are to be used in Sweden must follow Swedish regulations.

Plant protection products can affect your compost

Keep in mind that houseplants and cut flowers that you buy at the store can be treated with chemical plant protection products. Some of the agents contain substances that affect the growth of plants and can remain in plants and in soil for a long time. Therefore, it is a good idea to avoid composting houseplants and cut flowers. The substances that affect growth can remain in your compost, and in that case, there is a risk that they will affect the plants you grow in the finished compost or the plants you fertilise with the compost.
