Insecticides

Acaricides

Biopesticides

Beneficial insects, mites, nematodes, micro-organisms for biological pest control

Fertilizers (soil treated or leaf fertilizers)

Fungicides

Herbicides

Nematicides

Molluscicides

PGRs (Plant Growth Regulators)

Selectivity / Crop safety

Storage diseases

Soil disinfection/soil fumigation

Spray and application techniques versus product efficacy

Fruit Field trials

In apple, pear, cherry, strawberry, raspberry, blackberry, red currant, blueberry, etc..  and since recently also in our own vineyard

In non-protected fruit crops as well as protected crops (glasshouses, plastic tunnels, hail nets, etc.)

Efficacy Trials (GEP and non-GEP)

Protocols according to EPPO standards (link Eppo site: https://www.eppo.int/RESOURCES/eppo_standards)

Plant safety or phytotoxicity (GEP and non-GEP): in our specially designed multivariety orchards (apple/pear) allowing to get results for all main apple (13) and pear (9) varieties

Side effects and prey:predator ratio studies

                Yield, size and quality testing

                Taint tests (fresh and processed)

                Baseline resistance monitoring

                Residue studies (non-GLP)

                Many fruit or pest-specific field trials composed and validated by pcfruit experts…

For example: Trap and lure efficacy on fruit pests (link pdf file, see below)
