Crop Production: Switzerland - Biosuisse
SEEDS AND PLANTING MATERIALS
- Use of genetically modified seeds and transgenic plants is prohibited.
- Use of hybrid seeds in cereal production (with the exception of maize) is no longer permitted.
- It is mandatory for the planting material of vegetable and herb production as well as vegetative propagating material in top-fruit and soft-fruit plantations
to be derived from Bud holdings. - The use of peat for the cultivation of planting material should be as limited as possible.
CROP PROTECTION
- The proper choice of variety, soil management for improved tilth, well-balanced fertilizer use, appropriate cultivation techniques (e.g. crop rotation, crop type, mixed cropping, sufficient space between plants, green manure) aim at preventing the incidence of pests and diseases.
- For the direct control of pest organisms, mechanical and biotechnological methods are permitted.
- Weed control is carried out through cultivation and mechanical methods.
- The use of chemically-synthesized or genetically engineered crop protection products is prohibited.
- Detectable residues of such products on the organic produce should not exist unless they originate from a general contamination of the environment.
- Flame weeding is permitted.
- Steam treatment of soils out of doors is prohibited.
- The use of herbicides or growth regulators (straw shorteners, chemical fruit thinning, chemical soil disinfection or stem weakening agents etc.) and wilting agents is prohibited.
Permitted crop protection products:
- Insect regulation with pheromones, such as the confusion technique
- Repellents of plant or animal origin
- Natural predators, eg parasitic wasps, predatory mites, nematodes and gall midges, in the field and in greenhouses
- Naturally occurring microorganisms, such as Bacillus thuringiensis, granulosis virus, and fungi which are insect pathogens
- Mechanical defensive measure, such as protective nets, slug-proof fences, adhesive plastic chromatic traps and sticky bands
- Sulphur products, in low doses which allow predatory mites to survive, in orchards, vineyards, and vegetable growing
- Inorganic copper products, for fruit, vegetable, potato and hop production and viticulture (maximum legally permitted application of 4 kg of pure copper per hectare and year), maximum permitted application of pure copper per hectare and year of treated surface
- Pome fruit 1.5kg
- Stone fruit 4kg
- Soft fruit 2kg
- Vegetables 4kg
- Potatoes 4kg
- Hops 4kg
- Viticulture 4kg
- Products based on soft soap
- Plant extracts such as pyrethrum, rotenone, quassia, tobacco
- Plant oils and mineral oils
- Sulphur preparations
FERTILIZERS AND SOIL CONDITIONERS
Permitted soil conditioners and fertilizers:
