IUPAC CropChem News – Issue 3 – February 2023

The IUPAC Advisory Committee on Crop Protection Chemistry is an international group of volunteers comprised of approximately thirty scientists from academia, industry, government, regulators and private consultancies dealing with crop protection, pesticides and their behavior in food and the environment. The Committee is part of IUPAC Division VI, and we provide, via a project system, unbiased and timely authoritative reports and reviews on topical issues. For more information on IUPAC Projects see information on the IUPAC Project Page. CropChem News is an effort to disseminate committee activities, share information on upcoming events in the crop protection community, and to increase cross-sector dialog on news and discoveries on crop protection.

Advances on the Assessment of Pesticides Soil Microbial toxicity

In this issue of CropChem News, we highlight a new Technical Report publication in the October 2022 issue of Pure and Applied Chemistry, resulting from an IUPAC project 2014-032-1-600: “Advances on the Assessment of Pesticides Soil Microbial toxicity: New research and regulatory aspects in light of the recent methodological advances”, led by Dimitrios Karpouzas (University of Thessaly, Greece).

This publication “Pesticide soil microbial toxicity: Setting the scene for a new pesticide risk assessment for soil microorganisms (IUPAC Technical Report)” was authored by Dimitrios Karpouzas with the co-authors Zisis Vryzas (Democritus University of Thrace, Greece) and Fabrice Martin-Laurent (INRAE, France) providing proposed guiding principles of a revised pesticide risk assessment scheme focused on the protection of soil microorganisms and associated ecosystem services.

Advances and limitations in the experimental approaches used in soil microbial ecology are reviewed, scientific gaps are identified and mitigation solutions are proposed.

Recent work in the assessment of the soil microbial toxicity of pesticides are summarized. Ammonia-oxidizing microorganisms and arbuscular mycorrhizal fungi, as most relevant bioindicator groups providing substantial services in agricultural production, are proposed to support a tier-based risk assessment scheme.

Dimitrios Karpouzas commented,

“Today, a set of standardized ecotoxicity tests supporting the risk assessment are in place to assess the toxicity of pesticides on aquatic organisms and soil fauna, unlike soil microorganisms, whose ecotoxicological response to pesticides has not been set as a priority in the current risk assessment framework. This is surprising if we consider the number of key ecosystem services provided by microorganisms in soil.

A non-exhaustive list of such services includes their role in: (i) nutrient cycling, modulating soil fertility; (ii) increasing plant tolerance to biotic (pests and diseases) and abiotic (drought, salinity) stressors; (iii) the uptake of nutrients by plants, hence promoting plant growth and agricultural productivity; (iv) the maintenance of soil structure.

All the above highlight the need for a scheme to assess the toxicity of pesticides on soil microorganisms. This should consider the recent impressive methodological advances in soil microbial ecology coinciding with the upsurge of methods standardization.”

Each year IUPAC endorses a large number of independently organized conferences, symposiums and workshops that cover a wide range of specialized topics in chemistry.

For details, please see the IUPAC Calendar of Events.

Endorsement by IUPAC attests to the quality of the scientific program and indicates the host country’s assurance that scientists from all countries may participate. See the IUPAC website more details on Applying for IUPAC Endorsement of a Conference or Symposia

We are highlighting a signature event for IUPAC Division VI! The 15th IUPAC INTERNATIONAL CONGRESS OF CROP PROTECTION CHEMISTRY “Futuristic Approaches towards Seed to Market Strategies”, will be held during 14th-17th March 2023 in New Delhi, India at Bharat Ratna C. Subramaniam Auditorium (NASC Complex).

The Congress promises to be a gathering of next generation crop health scientists and professionals for whom your presence will be a source of inspiration. The venue is built in the heart of city, close to the center for Green Revolution in India, IARI, and can accommodate more than 1500 scientists interested in crop protection chemistry. We hope to see a galaxy of world-renowned speakers from academia, industry, government and many others.

The congress will provide a forum for scientists from different disciplines, in academia, industry and other areas to discuss latest trends and discoveries in agrochemicals and phytomedicines, and to deliberate on important issues of agricultural research, presenting their views as policy inputs to the planners, decision/opinion makers at various levels. Participating at the Congress will give you the opportunity to broaden your network and to reach out to your fellow crop protection scientists.

18 to 25 August 2023 – IUPAC WORLD CHEMISTRY CONGRESS 2023 ‘Connecting Chemical Worlds’ IUPAC|CHAINS2023 is organized by the Royal Netherlands Chemical Society (KNCV) and the Dutch Research Council (NWO). The IUPAC World Chemistry Congress is organized biennially with recent previous editions in Sao Paolo (2017), Paris (2019) and digitally in Montreal (2021). In 2023 we expect to welcome you on location in The Hague to meet each other in person.

The conference consists of the 52nd IUPAC General Assembly (18-25 August 2023) and the 49th IUPAC World Chemistry Congress combined with the 11th edition of CHAINS, the largest chemistry congress from the Netherlands (20-25 August 2023).


15 to 19 October 2023 the 31st International Symposium on the Chemistry of Natural Products and the 11th International Congress on Biodiversity (ISCNP31 & ICOB11), originally scheduled for 2020 and postponed because of the worldwide COVID19 outbreak, will be held on October 15th -19th 2023 in Napoli, Italy. The main aim of this conference is to highlight advancements, innovations and future perspectives in this long tradition and fascinating area of research of chemistry of natural products and biodiversity science and to create a fruitful environment that promotes international collaborations and cross-fertilization of ideas. Experts and young scientists will have the opportunity to present their research, while industrial representatives will present the latest applications of natural products.


30 June to 4 July 2024 the International Biotechnology Symposium Congress will be jointly organized with ECB, the Congress of European Federation of Biotechnology and with NBC, the annual Netherlands Biotechnology Conference, in Maastricht.

The joint IBS2020, ECB2020 and NBC-20 will showcase frontline science that will form the basis for future commercial innovation. The scientific program reveals an excellent line-up of plenary lectures and invited speakers. In line with the IBS and ECB tradition, the participation of young scientists will be promoted by encouraging them to submit original work to be considered for presentation as short talks or posters.
