Plant protection products, biocides, fertilisers and macro-organisms

Plant protection products and biocides are used by professionals and individuals on harmful organisms to destroy, deter or render them harmless. Before they can be placed on the market, the Agency is responsible for assessing the effectiveness of these products and the risks associated with their use. It also assesses fertilisers, growing media and macro-organisms.

Our actions

Regarding marketing authorisations, these are issued on the basis of the findings of the scientific risk assessment, by ANSES for plant protection products, fertilisers and growing media and their adjuvants, and also for biocides.

The Agency also monitors residues of these products in food and the environment, and the emergence of resistance to these products.

Review of ANSES’s work on prosulfocarb

Prosulfocarb is one of the most widely sold herbicidal active substances in France. For several years now, ANSES has been paying close attention to the problems posed by spray drift of prosulfocarb products. For example, the Agency has examined deposits on non-target crops following prosulfocarb treatments. It has also updated its assessment of products with regard to the exposure of local residents. Below we take stock of the work carried out by ANSES since 2017.

Bed bugs are a financial burden and reduce quality of life for many people in France

Between 2017 and 2022, more than one in 10 French households were infested by bed bugs. Contrary to popular belief, their presence does not indicate a lack of cleanliness, and anyone can fall victim to an infestation in their home. Moreover, bed bugs are a costly nuisance for households in metropolitan France, considering the expense of treatment and the psychological impact. The Agency therefore recommends that certain households be provided with financial assistance to cover the costs associated with exterminating bed bugs. It also recommends that professionals and private individuals favour alternative control methods instead of chemical insecticides.

Proposal of criteria to restrict self-service sales of biocidal products

Insecticides, hand sanitiser gels, rodent baits and surface disinfectants belong to a class of products called biocides that are part of our everyday lives. In order to reduce their impact on human and animal health and the environment, the French EGAlim Act provides for a ban on self-service sales of certain products to the general public. In this context, ANSES was tasked with defining criteria to determine which categories of biocidal products deserve special attention and restrictions on access. These products would nonetheless remain available for purchase under conditions to be defined by the authorities.

Drosophila as a model for exploring the effects of pesticides on Parkinson’s disease

The Drosophila melanogaster or fruit fly may be used to assess whether pesticides induce an increased risk of developing Parkinson’s disease. This was the conclusion reached by scientists in the ANSES Lyon Laboratory’s Neurodegenerative Diseases Unit, who have been collaborating with researchers from the École Normale Supérieure in Lyon. Working on paraquat, they also showed that the effects of this compound on proteins were not strictly identical to those of ageing. We interviewed Jean-Noël Arsac, one of the authors of the study.

Could mosquito traps provide an additional tool for controlling vector-borne diseases?

Mosquito traps are increasingly used in public spaces as a means to prevent mosquito bites and to control mosquito-borne diseases. However, the studies currently available are not sufficient to demonstrate the short-term effectiveness of these traps in preventing the spread of mosquito-borne diseases. ANSES is therefore encouraging their use primarily as a preventive measure (in the medium and long term) to reduce high mosquito density as part of an integrated control strategy. ANSES also points out that the marketing and use of these traps must comply with regulations. In recent decades, a number of mosquito-borne diseases – such as dengue, chikungunya and Zika – have spread outside tropical regions. The use of mosquito traps as a complement or alternative to other techniques for controlling the spread of viruses, is a relatively recent idea. In France, the operators responsible for limiting the spread of mosquitoes are appointed by the Regional Health Agencies (ARSs). Some 15 operators currently exist, but they do not all use mosquito traps in the same way. ANSES conducted a literature review to assess the effectiveness of the mosquito traps used by operators as part of vector control. Several ways to attract female mosquitoes Two main types of trap are used to catch female mosquitoes, which are the only ones able to bite and to transmit pathogens. The first type of trap simulates an egg-laying site. A water-filled container uses a variety of means, including insecticide and glue strips, to trap the females when they come to lay their eggs. The second type of trap attracts mosquitoes by simulating the breathing of a living being through the diffusion of carbon dioxide (CO2) and/or the use of visual or olfactory attractants (for example, lactic acid to simulate human body odour). A control method to be used alongside other techniques “ We have a body of evidence showing that both types of trap can have a preventive effect in reducing the mosquito population in the medium and long term (over several weeks, months, or even years), providing that they are well maintained and used in sufficient numbers ,” says Johanna Fite, head of the "Vectors" unit at ANSES. “ However, they are not a magic solution. Traps are most effective when used in conjunction with other control methods , particularly the elimination of breeding sites. " No studies concerning the impact of traps on the spread of disease Some operators place traps when cases of vector-borne disease are identified. Traps are set up for a period of three to six weeks around the homes of infected people. The expert appraisal conducted by ANSES identified no data shedding light on the effectiveness of traps in quickly containing the spreading of disease when the viruses are already in circulation. The Agency therefore recommends that research be carried out in order to collect data on this question and to determine the best conditions for the deployment of these traps, based on different epidemiological scenarios, including an isolated case, an outbreak and an epidemic. Pending these additional data, mosquito traps should be used only as a preventive measure, or in cases where it is not possible to use an insecticide, for example when the area to be treated is inaccessible or close to a waterway. A reminder needed of the regulations CO2, lactic acid and other substances used to attract female mosquitoes are biocidal substances. Traps using these substances must therefore comply with the regulations on biocides . They also require marketing authorisation (MA). To date, no applications for marketing authorisation have been filed in France for mosquito traps using CO2. Under the terms of a transitional regime, the marketing of traps using CO2 produced through combustion is authorised until July 2022. After this date, it will no longer be possible to sell traps without a marketing authorisation in France. Applications for marketing authorisation must include documentary proof of the effectiveness and safety of these traps. Finally, devices will not be able to make claims such as "zero nuisance" or "mosquito-free home" without proof.

Why is it important to limit our use of biocidal chemicals?

Disinfectants, insecticides, repellents – in our daily lives, we use chemical products known as “biocides” that can be toxic to our health and the environment. Sometimes, they are used excessively and for non-essential purposes, contributing to increasing our exposure to chemicals and potentially leading to resistance in target organisms. Why should we limit our use of these products, and how can we do so? ANSES answers your questions.

Risks of dietary exposure to chlordecone in the French Caribbean

Chlordecone is a pesticide that can pose a risk to human health. It was used in banana plantations in the French Caribbean until 1993. Being very persistent, it has permanently contaminated the soil and water, and even today has an impact on crops and livestock production. Since the early 2000s, ANSES has been working to improve knowledge on exposure of the French Caribbean population to this contaminant and the associated health risks. In particular, it has made recommendations on the consumption of locally produced food.

What are the health issues and environmental challenges presented by herbicide-tolerant varieties?

Herbicide-tolerant varieties (HTVs) are crop varieties that have been developed to be intentionally tolerant to specific herbicids. In France, HTVs of sunflower and rapeseed have been growing in popularity since the early 2010s. In a changing regulatory context and in order to address public concerns, the Agency has conducted several studies to assess the farming practices reshaped by the use of HTVs and identify their potential risks for farmers, consumers and the environment. We provide an overview of the challenges that need to be overcome to improve the traceability and monitoring of HTVs in France.

Neonicotinoids are a class of insecticidal substances. The use of neonicotinoid products in agriculture has raised concerns in many countries, primarily because of their effects on pollinating insects. New scientific evidence has led the European Union to progressively restrict the uses of these substances, leaving only two approved for plant protection purposes. In France, the use of neonicotinoid products has been prohibited in agriculture since 2018. ANSES has conducted extensive work to assess the effects of these substances on bees and has been particularly active in strengthening the requirements for using these products.

Contamination of air by pesticides

Air pollution caused by pesticides is one of the components of atmospheric pollution. However, it is still less well documented than the contamination of water or food by these same substances. There is currently no national surveillance plan or regulatory value for pesticide contamination of the various air environments (outdoor and indoor air). Because improving air quality is a major public health issue, a national plan for the reduction of atmospheric pollutant emissions (PREPA) has been implemented as a roadmap for achieving this, through some 50 actions. These include the national exploratory campaign to measure pesticides in outdoor air (CNEP), led by ANSES alongside Ineris and the AASQA network, with a view to establishing permanent targeted monitoring at national level.

SDHI Fungicides

On 14 January 2019, after being alerted by a group of scientists, ANSES published an opinion on the assessment of a warning signal regarding the toxicity of succinate dehydrogenase inhibitor (SDHI) fungicides. Based on a review of all the scientific data currently available, carried out by a group of independent experts, ANSES concluded that there was no health alert justifying the withdrawal of marketing authorisations for these fungicides. However, it called for vigilance at European and international level and stressed the need to step up research on potential toxicological effects in humans. Work to examine this warning signal regarding SDHI fungicides has been continuing since January 2019 in three areas: the definition and funding of specific research, the detection by existing surveillance schemes of possible health effects that may be observed in the field, and lastly, exchanges with research organisations and health agencies tasked with assessing these substances, in particular the European Food Safety Authority (EFSA). In late 2019, ANSES decided once again to examine the issue of SDHIs and mobilised its expert groups with the aim of reviewing the most recent literature data , in order to benefit from any new insights since the expert appraisal conducted in 2018. The first results will be published in the end of 2021.
