Two categories exist for vegetable crops: “Standard” for seeds and “CE” for plants, and “Certified”, an optional superior grade.
For seed-propagated species:
Certification guarantees the varietal conformity and uniformity of seeds, and when necessary the required seed health standards e.g. tomato seeds free of Clavibacter, and bean seeds free of grease spot. In practice, French seed producers and breeding companies ensure a high level of quality, and these varieties are marketed in the form of “Standard” seeds and “CE plants”. The “Certified” grade is sometimes required for exports.
With vegetatively propagated species, the Certified grade is much more widely used for seed health reasons, as harmful organisms are propagated by multiplied organs. For garlic, shallot, strawberry, asparagus crowns, and mushroom inoculum, seeds and plants are produced at Certified grade (around 50% of plant production) and are free of pathogens such as nematodes, viruses, and pests specific to each species.
