The IUPAC Advisory Committee on Crop Protection Chemistry (group photo below) 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. IUPAC 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.

IUPAC Congress Comes to New Delhi in 2023
Since the first Congress held at Vienna in 1967, crop protection experts have been sharing their views and solutions on emerging issues in agriculture of global significance. However, the lack of understanding among various communities about crop protection chemicals still persists, with many export commodities being rejected by different countries. There is a need to tackle this issue both at a National and International level, bringing together various stakeholders on one platform. The 2023 Congress will be focused on following themes:
- Development of natural and synthetic agrochemicals
- Develop innovative pesticide formulations
- Emerging issues and stewardship
- Precise analytical techniques for environmental fate and metabolism
- Environmental fate and metabolism
- Soil microbiome, metabolomics
- Creation of awareness program on judicious use of plant protection chemicals
The 15th IUPAC International Congress on Crop Protection Chemistry will be hosted by the Society for the Promotion of Sustainable Agriculture (SPSA), in association with ICAR-Indian Agricultural Research Institute (IARI), New Delhi and Institute of Pesticide Formulation Technology (IPFT), Gurugram, and take place at National Agricultural Science Centre Complex (NASC Complex) in New Delhi, India.

IUPAC Project Highlights
The IUPAC Project “Inventory of Developments in the Field of RNAi-Based Pesticides and Potential Needs for International Harmonization of Regulatory Safety Requirements“, is led by Dr. Gijs Kleter of Wageningen Food Safety Research in Netherlands. He has recently published a mini-review paper in Pest Management Science.
Kleter, G. A. 2020. Food safety assessment of crops engineered with RNA interference and other methods to modulate expression of endogenous and plant pest genes. Pest Management Sci. https://doi.org/10.1002/ps.5957
Abstract: Genetically modified crops have been grown commercially for more than two decades. Some of these crops have been modified with genetic constructs that induce gene silencing through RNA interference (RNAi). The targets for this silencing action are genes, either specific endogenous ones of the host plant or those of particular pests or pathogens infesting these plants. Recently emerging new genetic tools enable precise DNA edits with the same silencing effect and have also increased our knowledge and insights into the mechanisms of RNAi. For the assessment of the safety of foodstuffs from crops modified with RNAi, internationally harmonized principles for risk assessment of foods derived from genetically modified crops can be followed. Special considerations may apply to the newly expressed silencing RNA molecules, such as their possible uptake by consumers and interference with expression of host genes, which, however, would need to overcome many barriers. Bioinformatics tools aid the prediction of possible interference by a given RNA molecule with the expression of genes with homologous sequences in the host crop and in other organisms, or possible off‐target edits in gene‐edited crops.

United Nations International Year Celebrations
The United Nations has declared 2020 as the International Year of Plant Health (IYPH). “The year is a once in a lifetime opportunity to raise global awareness on how protecting plant health can help end hunger, reduce poverty, protect the environment, and boost economic development” However, the current COVID-19 epidemic has led to many events being postponed. Below are few of the upcoming events:
- International Plant Health Conference “Protecting Plant Health in a changing world” June 28 – July 1, 2021, Helsinki, Finland
- 26th International Congress of Entomology, July 18-23, 2021, Helsinki, Finland
- 14th International Conference on Plant Pathogenic Bacteria, “The Impact of Plant Pathogenic Bacteria on Global Plant Health” June, 6-11, 2021, Assisi, Italy
- 2021 NAPPO Annual Meeting and North American Safeguarding Conference, August 9, 2021, Washington, USA
- Plant Health, Agriculture & Bioscience Conference, Sept, 22-24, 2021, The Hague, Netherlands
