Certificazione GEP – Good Experimental Practice

Since 1999, Repros holds the GEP (Good Experimental Practices) certification issued by the Italian Ministry of Agriculture for conducting evaluation trials on plant protection products for registration purposes (assessments, tests, field trials).

GEP (Good Experimental Practice) ensure that the field tests that evaluate the efficacy and selectivity (phytotoxic effects and on non-target organisms) of a given product are conducted in accordance with uniform principles, guaranteeing a high quality and mutual recognition at Community level.

Plant protection products must be authorized accordingly to the plant protection regulation (REGULATION (EC) No. 1107/2009 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL) before they can be marketed and used. This authorization process involves a thorough evaluation of the properties of plant protection products.

The GEP certification allows REPROS to conduct official agricultural experimentation studies on plant protection products for the pest-control industry (product effectiveness test, production yield and quality assessment, phytotoxicity, side effects).

The term field crops refers to experimental studies conducted on corn, cereals (wheat, barley, oats, triticale, rye), protein crops (peas, soybean), oil seeds (sunflower), potatoes, sugar beet, vineyards and orchards.

The GEP certification guarantees a complete traceability of the test procedures (based on a set of procedures controlled by our staff, from the search for a test site in the field suitable to the preparation of the final report) and therefore allows the use of the test data collected for registrations of plant protection products.

Repros uses the ARM software (Agriculture Research Manager) for data recording.

 

 

Plant protection products

Plant protection products are preparations containing at least one active substance intended for the protection of plants or plant products against pests and diseases, promoting or regulating the life processes of plants, preserving plant products and controlling the growth of weeds.

Before a plant protection product can be authorized at Member State level and placed on the market, the active substances contained in the formulated product must be approved at EU level.

The evaluation of the active substance is performed by the Authority of a designated Member State which organizes a draft evaluation report on the data submitted.

After EU approval of the active substance, data concerning the formulated product containing the approved active substance should be considered.

Each Member State, where the use of the product is requested, takes the decision to grant the complete or conditional authorization or not to grant it. The evaluation procedure for authorization is based on the harmonized EU principles taking into account specific and local situations.

 

The "new" regulation (EC) No. 1107/2009 entered into force in June 2011 and establishes harmonized standards for the approval of active substances and the placing on the market of plant protection products.

The main changes introduced are the criteria for the preventive exclusion of hazardous substances, a simplified authorization procedure for the substances identified as low risk and the zonal authorization of the products for mutual recognition in the EU Member States.

The principle of mutual recognition is one of the means of ensuring the free movement of goods within the Union.

To facilitate this mutual recognition, the Union territory has been divided into zones with comparable conditions, therefore authorizations granted by a Member State should be accepted by other Member States in which the agricultural, plant health and environmental conditions are similar, avoiding duplication of work and providing a more harmonized availability of plant protection products.

The purpose of this regulation is to ensure that active substances and products have no harmful effect on human or animal health or unacceptable effects on the environment, preserving the competitiveness of European agriculture.

GEP trials

Repros employs a trained staff that performs full field activities on plant protection products.

The performance of effectiveness tests (GEP) in the field includes the overall management of the studies, or rather the planning, the execution, the evaluation, the recording and the interpretation of the results to guarantee high levels of reliability and traceability.

The GEP trials are performed following the EPPO standards on the evaluation of the effectiveness of plant protection products in their most up-to-date version.

Evaluating the efficacy of a plant protection product is a prerequisite for its authorization. The efficacy trials provide information for the evaluation of the product’s performance against parasites, and on the nature and extent of any harmful effects on the crops, on the yield of the treated crops and of the subsequent ones.

The nature and extent of the benefits deriving from the use of a plant protection product are therefore compared with existing reference products and with certain damage thresholds, allowing the conditions of use to be established.

These tests allow the assessment of the level, duration and uniformity of the control / protection or other effects deriving from the product.
