Studies & Testing
Scientific data for concrete decisions
GEP and GLP studies, Biostimulants and Plant Nutrition products testing, everything both in indoor at outdoor conditions: find out about our operational part.
GEP Studies
The heart of our work: assessing products efficacy and crop selectivity
Through the registration studies conducted in GEP(Good Experimental Practices) are field-tested for efficacy against pests, weeds or diseases and selectivity toward crops. Thus, one valid data are obtained to be submitted in applications for registration.
At Agrigeos, efficacy and selectivity studies (GEP) are at the heart of the business: we test herbicides, fungicides, insecticides, nematicides e PGRS, with defined protocols in the field e postharvest. We offer specific tests on shelf-life, beneficial insects, resistance to leaching, triangular testing e seed tanning, for reliable and tailored scientific results.

Post collection
Tests on dip- or drench-treated fruits, including directly in processing warehouses. Shelf-life evaluation on fruits, vegetables and IV gamma products.
Non-target arthropods and beneficial insects
Selectivity testing to verify that products do not harm predators, parasitoids, and pollinators
Studies in Greenhouse
Greenhouse studies is about testing products on crops grown indoor mainlyvegetables and ornamentals.
At our testing facility located in Acate, in the heart of the Sicilian production area, we can conduct tests on critical targets such as nematodes, on insects and fungal diseases. In recent years, thanks to the network of farmers with whom we collaborate, we can also set up trials on biostimulants and fertilizers.
Seed coating
Application of liquid or powdered coating products directly to seeds to test the effectiveness of biostimulants, fungicides and insecticides.
Other studies
Resistance and sensoriality
Resistance and sensory studies help companies understand how their products behave under certain conditions of use.
These studies help to improve formulations and offer reliable and sensorially consistent products.
Resistance to runoff (Rain fastness)
Studies on product runoff using rain simulation to assess water resistance.
Triangular tests (Taint triangle test)
Sensory tests on fresh and processed fruits (such as sauces, wines, or juices) to detect any changes in taste or odor following EPPO guideline PP 1/242 (2) Taint tests

GLP studies
Residues under control, according to regulations
With the GLP (Good Laboratory Practices) studies. it is possible to assess the residues that a product leaves on plants, fruits and processed products, according to rigorous protocols recognized at the European level. They are essential for obtaining marketing authorization for plant protection products and useful for indicating deficiency times on the label.
We are accredited by the Ministry of Health in Italy to conduct residue studies on various matrices. For companies, this means Having certified and valid data for registration.

Residues on pollen, nectar and honey
Field phase for the determination of residues on pollen nectar and honey (sampling and evaluation also conducted due to our in-house bee farms).
Residues on processed products
Field and processing phase for evaluation of the effects of industrial processing and/or home preparation on the nature and extent of residues. (Analysis of oil, wine, juices, jams and other derivatives, processed directly in our processed laboratory).
Residues on dust
Field phase of the collection of dust produced during agricultural activities using sheets and plates to simulate the dispersion of dust contaminated with plant protection products.
DFR - Dislodgeable Foliar Residue
Field phase and sampling of residues removable from leaves by washing in saline solutions simulating human sweat for determination of re-entry times in a field after application of plant protection products.
Rain fastness
Field phase of a study of runoff resistance of cover crop protection products by simulating rainfall events using a rainfall simulator.
Studies on Biostimulants and Fertilizers.
We assess plant growth, measure health status efficiency and response to abiotic stresses
Studies on biostimulants and fertilizers serve to verify their efficacy, identify the best conditions of use, and collect useful data for their technical and commercial development.
Horticultural crops
We conduct seasonal field and greenhouse trials to evaluate growth, yield, and response to abiotic stresses (drought, salinity, heat).
Tree Crops
Citrus, grapevine, olive and stone fruit are the main crops. We also test emerging tropical fruits such as avocado and mango, with opportunities for pot trials from the early stages of transplanting.
Extensive crops
Cereals, potato, corn, sunflower, soybean and beet are sown in larger crop clusters due to our favorable climate. Potato, in particular, allows us two test cycles per year.
Ornamental
Through collaboration with specialized nurseries, we conduct studies on a wide range of ornamental species, evaluating growth, uniformity, and resistance to environmental conditions.
PLUS services: what differentiates us
Drone surveys
An integrated service we offer for biostimulant studies. Through the analysis of aerial images we detect parameters such as NDVI, GNDVI, NDRE, LAI, GRVI and other vegetative indices, useful for monitoring crop response quickly and noninvasively.
PlantArray®
An advanced phenotyping platform that measures: cplant rescission (daily biomass); traspiration and water use; cstomatal conductance (gas exchange efficiency); cwater content in the substrate; penvironmental arameters such as temperature, humidity, light and pressure.
Screening Trials
It all starts here: quick testing at controlled conditions
With laboratory screenings we assess in a rapid and controlled manner the efficacy and behavior of substances (such as active ingredients, repellent/attractive compounds, etc.) before moving on to registration trials in the greenhouse or field.
They are critical to select the most promising formulations, identify dosages and possible criticalities from the earliest stages of development, evaluate the miscibility with other substances and the mode of application.
Insect breeding
To ensure the constant availability of specific targets on which to perform tests under controlled conditions and provide inoculums for efficacy trials by ensuring homogeneous target presence.
Pathogen Collection
Collection and maintenance of phytopathogenic fungi and bacteria for in vitro, in vivo screening trials and inoculum production for efficacy trials.
Nematode breeding
To ensure its continued availability for in vitro tests, inoculation, and pot-based screening.
Specific methods applied in screening
Effectiveness testing:
Evaluation of the sensitivity of a target to a substance, preliminary to subsequent tests.
Knock-down test:
Measurement of the rapidity of action of the product on the target insect.
Semi-camp:
Intermediate tests between laboratory and field, under partially controlled conditions
Persistence:
Evaluation of the duration of the protective or active effect.
Mixing test:
Evaluation test of synergy/antagonism between multiple active substances.
Application test:
Identification of the most effective application method (spray, drip, drench, etc.).
Tests on mode of action and kinetics:
Evaluation of the behavior of an active substance on the target (contact, ingestion, etc.) and on the plant (e.g., systematics).
Endurance:
Analysis of target response to repeated exposures to identify resistance phenomena.
Choice test:
Evaluation of the olfactory effectiveness of attractants or repellents by use of olfactometer.
Test degradation and runoff:
simulations to test the product's resistance to rain runoff (rain tower) or UV degradation (UV chamber).
