Our history

frise chronologique histoire Cotesia

Crop protection

Field tests measuring efficiency, selectivity and impact on auxiliaries.

COTESIA by IZInovation conducts trials to measure the level of effectiveness and confirm the selectivity of crop protection solutions in the research phase.

These trials take place within a network of partner farmers located in the south-west. This network makes it possible to select the most favorable geographical areas to each study objective.


Protective solutions

These crop protection solutions can be synthetic pesticides, biocontrols, pesticides usable in organic agriculture, solutions allowing activation of natural plant defense systems (PDS).

Our expertise makes it possible to adapt study protocols to the specificities of these different approaches.

The biological activities measured concern the actions

– fungicides,

– insecticides,

– herbicides,

– physiological regulation (Plant Growth Regulators).


Our approved sectors of activity

The tests are carried out on :

– vine,

– fruit growing(apple, peach),

– vegetable crops,

– field crops (mainly corn, straw cereals, rapeseed, potatoes, soybeans and sunflowers).

For each type of project and for each use studied, COTESIA by IZInovation offers a methodological adaptation to optimize the official EPPO methods.


COTESIA by IZInovation, research structure involved in the search for innovative solutions

Since 2005, the company COTESIA by IZInovation has structured its approach on scientific, technical and rational bases.

The generally lower effectiveness of innovative bio-solutions (biocontrols) requires creating new methods and optimizing experimental practices.

From the first field trials, consideration of the integration of these bio-solutions into integrated protection programs is essential. This approach encourages us to offer potential partner products, made possible by our expertise in phytopharmaceutical solutions.

For biosolutions, COTESIA by IZInovation offers adapted technical development compatible with official EPPO methods.

Fertilizers / Biostimulants

COTESIA by IZInovation, research structure in fertilization/biostimulation experimentation.

In a scientific and technical approach, COTESIA by IZInovation is testing innovative fertilizer solutions capable of optimizing agrosystems. Innovative fertilizers (biostimulants) cause a quantifiable physiological induction on plants. This quantification involves optimizing experimental practices to make them compatible with the criteria to be measured: development of aerial parts and the rhizosphere, modification of photosynthesis, etc. In addition, the results of the first field trials make it possible to guide the preparation studied within the regulatory framework that corresponds to it: fertilizer or bio-stimulant, plant protection product or biocontrol. A chaque type de préparation fertilisante et pour chaque critère étudié, COTESIA by IZInovation propose une adaptation méthodologique permettant d’adapter et d’optimiser les méthodologies couramment utilisées.

Tests under controlled conditions

Evaluation of the mode of action and selectivity of preparations, under tunnels, greenhouses, semi-field or laboratory.

For monitoring specific criteria such as insect damage or the direct effect of a preparation on a crop (selectivity) or a pest (effectiveness), Semi-field or laboratory tests are preferable to full-field tests.

These tests make it possible to limit the experimental conditions to the treatment factor, which makes it possible to identify mechanisms which will subsequently be validated in the open field.

These trials are conductedin field crops and vegetable cropsmainly.

In addition to the biological data, an interpretation of the results by the people who participated in the field phases is provided.

BPE efficiency and selectivity tests

Evaluation of the effectiveness and selectivity of field preparations.

In accordance with the GEP principles, COTESIA by IZInovation staff actively participate in defining study protocols, setting up and carrying out efficacy/selectivity trials, data analysis and writing of study reports:

– Research trials / screening

– Approval tests

– Regional development trials.

These trials are carried out in vines, field crops, vegetable crops and fruit trees, in the maritime or Mediterranean area.

These tests concern fungicides, SDPs, insecticides, herbicides, adjuvants and growth regulators.

In addition to the biological data, an interpretation of the results by the people who participated in the field phases is provided.

Impact studies on beneficial insects

Evaluation of the impacts of plant protection preparations on non-target insects.

Since 2008, COTESIA by IZInovation has been working on developing a method for measuring impact on non-target insects (Diptera, Hymenoptera and Orthoptera).

This method is intended toimprove knowledge of the impacts generated by treatmentson non-target insects.

By improving technical knowledge, COTESIA by IZInovation makes it possible to improve the positioning of crop protection treatments in a context of respecting the natural balance of agricultural plots (environmental preservation and functional biodiversity).

These studies are carried out mainly on vines but can be applied to other crops (feasibility study on request).

Disease resistance studies

Measures of the impact of fungicide resistance in natural conditions.

COTESIA by IZInovation has been participating since 2012 in the validation of experimental methods, the carrying out of studies and the interpretation of disease resistance results.

This specific work (described in EPPO method 1/213) is complementary to laboratory sensitivity analyses. These studies make it possible to measure the level of sensitivity of natural strains to a preparation while measuring the possible loss of effectiveness in the field (concept of ‘practical resistance’).

These studies are essential for resistance management measures.

They make it possible to manage effective protection programs, based on multiple preparations whose positioning is optimized to ensure maximum effectiveness with a limited number of treatments.

These studies are carried out mainly on vines but can be applied to other crops (feasibility study on request).

Project management France and Europe

COTESIA by IZInovation is a research structure connected with plant protection players in France and Europe.

Based in the southwest of France (Pyrénées-Atlantiques), the company COTESIA by IZInovation has developed a network allowing it to manage projects in France and Europe.

Depending on the projects to be managed, COTESIA by IZInovation can approach the structures most suited to the desired themes and the expertise sought: private service providers,

technical centers, public research laboratories, distributors…

We are not limited by membership in a global structure or group!

Our independence is a guarantee of quality in the choice of our partners, which varies according to the needs of the project entrusted to us.

Regulation and approval

Cotesia by IZInovation staff have dual skills in experimentation and regulations applicable to crop protection.

The summaries produced from study reports are not compiled following simple mathematical logic! Due to its expertise in field experimentation, COTESIA by IZInovation staff carry out syntheses taking into consideration the cycle of pests and the stages of target crops. The summaries submitted in support of MA applications thus reflect agricultural practice. Each year, COTESIA by IZInovation drafts and monitors several DRRs (draft Registration Report = MA application files) in compliance with European Regulation 1107/2009 on behalf of client companies. Dès les phases d’évaluation de l’efficacité, COTESIA by IZInovation assure également un conseil réglementaire nécessaire à la construction d’un programme d’essai compatible avec les exigences réglementaires européennes.

Plant protection training / audits

Cotesia by IZInovation staff carry out technical audits and training in the field of crop protection research.

COTESIA by IZInovation staff provide training for researchers engaged in efforts to improve their experimental practices.

Regulatory reminders and explanations of GEP/GLP standards can be addressed with the aim of making researchers efficient in the evaluation of plant protection products.

The effectiveness of phytopharmaceutical solutions can also be approached from the angle of the product x target x material combination.

Carrying out technical audits on research sites also makes it possible to become aware of strong points and weak points on regulatory and technical levels: progress approach .
