IOBC-WPRS Pesticide Side Effect Database

CAUTION: The Pesticide Side Effect Database is currently under revision and cannot be accessed.

The database on selectivity of pesticides has has been prepared jointly by the IOBC-WPRS Working Group on “Pesticides and Beneficial Organisms” and the Commission “Guidelines for Integrated Production” to assist organizations and growers in the choice of pesticides.

Database with search functions:

  • Active Ingredient
  • Test Species
  • Species Group

The database

The aim of the IOBC database is to compile the effects of plant protection products on beneficial arthropods obtained according to the methods developed by the IOBC working group “Pesticide and Beneficial Organisms”, or following closely the IOBC “standard” characteristics”, as the studies performed during the registration process at the European level, that were performed with validated guidelines based on IOBC methodology.
The interpretation of the results, which is closely depending to the category of test methods used, the formulation and the doses assessed, the test organisms used and the context of use of the product, is not the responsibility of this database. Each data is linked to a reference that can be consulted for further details and assessment.

Origin of the data

The data compiled in the database were extracted from three major origins:

  • IOBC Joint Pesticide Testing Programs (JPTP), organized by the Working group in the 80s and 90s. The results of the 1st and 2nd testing program, where the methods used were not totally fully developed according the IOBC standards, have not been retained.
  • IOBC Bulletin, proceedings of the working group meetings, from the end of the JPTP till 2008.
  • DAR (Draft Assessment Report) – Public version, edited by the different rapporteur member state in the context of the registration process of the active substance at the European Level, available on the EFSA website.

Which data have been retained?

The laboratory data listed in the database were retained if the results on lethal effects (mortality) and sublethal effects (reproduction, feeding activity,…) were available for the most susceptible life stage, as described in the IOBC standard characteristics.  The rating was based on the combination of the two effects (Reduction in beneficial capacity). By default, the products were applied by aerial spray on the test area. Other application techniques (e.g. seed dressing, soil incorporated granules, etc…) are indicated as remark.

For field testing, the effects on population dynamics were used. For several field studies, only the group of species (e.g. phytoseiids mites, ladybirds, etc…) is indicated, as the results were obtained on population with a mix of different species or there was no precise identification at the species level.

Formulation that contained two or more active ingredients were not retained, except when the mixture was harmless and the different ingredients could then also be considered as harmless. They were compiled on basis of a single active ingredient compound for each active ingredient, at the corresponding dose tested in the mixture.

For each data, an evaluation of the quality of the results was performed (control mortality, clear description of the methods, identification of the products used and the doses, etc…) before using the results.

How to enrich the database?

Any contribution to update the database with new data is welcome. They can be send to JP Jansen ( The criteria for the acceptation of the new data will be the follow-up of the IOBC standard characteristics and the scientific validity of the data (e.g. data extracted from published paper in peer review journal, or accepted paper). The data, as they will be available on the IOBC website, must be free of confidentiality statement. Any new contribution will be assessed by the IOBC WG Pesticide and Beneficial organism convenor or the editorial board.
