Expert Groups

IOBC-WPRS encourages collaboration in promoting feasible and environmentally safe methods of pest and pathogen control.

The scientific and technical activity of IOBC-WPRS is carried by Working Groups, Study Groups and Commissions.

Such expert groups are composed of scientists and other professional IOBC-WPRS members and coming from at least three different countries.

Working & Study Groups

A Working Group (WG) is responsible for a precise programme and the evaluation of the results obtained.

Study Groups (SG) are Working Groups which are under construction.

Commissions

Commissions are in several practical aspects comparable to Working Groups. They are much more focused on a specific subject and consist of experts appointed by the Council of WPRS.

IP Tools

IP (Integrated Production) is a concept of sustainable agriculture based on agro-ecology and a system approach that aims at contributing to sustainable, resilient, profitable and robust farming systems. IPM (Integrated Pest Management) is the part of IP focusing on pests, pathogens and weeds .

Integrated Production Objectives and Principles

IP aims at contributing to sustainable, resilient, profitable and robust farming systems.

General and Crop Specific IP Guidelines

The overall aim of IOBC guidelines on Integrated Production is to provide inspiration for a consistent and integral application of Integrated Production principles in different production systems.

IOBC-WPRS Pesticide Side Effect Database

The database on selectivity of pesticides has has been prepared to assist organizations and growers in the choice of pesticides. It is restricted to IOBC-WPRS members.

The Pesticide Side Effect Database is currently under revision.
