Abstract Current problems of forest protection concern the declining health of forest stands due to climate change and the resulting extreme weather events such as heat waves, droughts, hurricane winds, heavy rainfalls and floods. Repeated impacts of these factors increase susceptibility of forest stands to pest insects and fungal pathogens. Norway spruce (Picea abies [L.] H. Karst) is sensitive to high air temperatures and water shortage. Long lasting droughts during the last two decades, have been one of the reasons behind Norway spruce dieback due to severe outbreak of European spruce bark beetle Ips typographus (L.) in the mountainous regions of southern Poland. In the Scots pine (Pinus sylvestris L.) stands, water balance disorders have enhanced the colonization of weekend trees by steelblue jewel beetle Phaenops cyanea (F.) and engraver beetle Ips acuminatus (Gyll.), as well as contributed to the spread of fungal diseases caused by Gremmeniella abietina (Lagerb.) Cenangium ferruginosum Fr. and Sphaeropsis sapinea Fr. fungi. Water related stress leads to weakening of oak stands, which are attacked by Agrilus spp. beetles and pathogens from the genus Phytophthora. It is possible that long lasting droughts initiated the spread of infectious ash disease caused by Hymenoscyphus fraxineus (= Chalara fraxinea), which resulted in the epidemic of ash dieback throughout Europe. Until recently, the use of plant protection products was the most common method of forest protection against pest insects and pathogens. Poland’s accession to the European Union has affected the marketing and use of plant protection products in the country. The implementation of the EU legislation (Directive 91/414/EEC, Directive 2009/128/ EC and Regulation No 1107/2009) has resulted in decreased assortment of pesticides registered for the protection of forests. High costs and long registration process considerably limited the interest of producers in placing the plant protection products on the market. Systematic decrease in the number of plant protection products possible to register for use in forestry, as well as the principles of integrated plant protection established in the EU in 2014 call for seeking plant protection methods based on the natural enemies of pests, such as pathogenic microorganisms, parasites and predators. Therefore, contemporary forest protection requires the advancement of integrated methods for pest insect and disease control through developing methods of forecasting forest dangers, the use of natural enemies and agro-technical methods for regulation of pests, as well as the development of decision support systems as a tool facilitating introduction of integrated forest protection principles. Such support systems help to establish optimal terms for the implementation of protection measures, so as to increase their efficiency while limiting the use of chemical pesticides to an absolute minimum.

Abstract The paper presents the history of legal changes regarding forest protection in Poland and the development of forest protection services Poland’s accession to the European Union in 2004 has affected the marketing and the use of plant protection products (PPPs) in the country. The implementation of the EU legislation (Directive 91/414/EEC) has resulted in a decline in the assortment of pesticides registered for use in agriculture, and in forestry. This situation resulted from the limited interest of producers in placing PPPs on the market. Furthermore, limitations in the aerial application of PPPs have been introduced, which has consequences for the protection of the forest, where aerial treatments are often the only way to reduce the number of pests. On the other hand, the introduction of integrated pest management (also in forestry) confirmed the adequacy of activities carried out in the State Forest National Forest Holding, where, for many decades, the prevention methods have been used to increase the resistance of stands and the multi-stage Decision Support System (DSS) is used to select the optimal protective method.

Currently, agricultural means of production are of great importance in agribusiness, in particular mineral fertilizers and chemical plant protection products. The article attempts to present and compare changes in the value of used fertilizers and plant protection products in European Union countries in 2010-2018. Changes in the value of used fertilizers and plant protection products per 1 ha of UAA and changes in the share of these means of production in intermediate consumption were examined. It was found that the value of used fertilizers and plant protection products per 1 ha of UAA increased on average in the EU. Their share in intermediate consumption also increased. As a result of grouping objects using the Ward method, 4 clusters of countries were obtained, which differed in terms of the proposed features, while the countries that created the given cluster were characterized by similar values of variables. The countries where both a clear increase in the value of used fertilizers and plant protection products per unit area as well as a significant increase in their value in intermediate consumption were observed: Lithuania, Bulgaria and Estonia. However, a decline in demand for the discussed means of production occurred in Belgium, Croatia, Slovenia, Denmark, Finland and Portugal.

The approval renewal of glyphosate as an active substance for pesticides in the EU has also kept the Court of Justice occupied. Within this line of case law, the Blaise case is the most recent one. In this preliminary reference procedure the Court was asked to review the validity of the Plant Protection Products Regulation 1107/2009, examined against the precautionary principle as benchmark. The case is relevant not only for the questions raised about the Regulation, but also as it sheds a light on the – albeit limited – use of the precautionary principle in the judicial review of EU legislative measure.

Spices are an important group of food products of great importance in nutrition and food technology. They are mainly used to shape the sensory properties of food in gastronomy, in home cooking, and in industry. Ensuring quality and safety is one of the basic tasks of spice producers. The aim of this review is to present the threats to the consumer related to the presence of spices and seasoning mixes in the diet. Therefore, special attention was paid to such risks as excess sodium chloride (and sodium) in spice mixtures, the use of additives influencing the sensory experience, and irregularities in the labeling of spices and seasoning mixes for the presence of additives and allergens. The threats regarding microbiological safety and the presence of heavy metals, pesticides, plant protection products, as well as synthetic fertilizers and undeclared additives are also presented and the issue of adulteration and lack of authenticity of spices and spice mixtures is discussed. Using data from IJHARS planned inspections and notifications registered in the EU Rapid Alert System for Food and Feed (RASFF) for 2015–2019, as well as the results of own research, an analysis of the risks caused by herbs and spices was carried out. Strategic activities of companies producing spices focus, among others, on improving production and expanding the commercial offer with new, attractive products. The article reviews product and process innovations in spice mixes and the methods of ensuring safety in this group of food products.

The EU decentralised agencies are involved in various sectorial EU policies and related composite procedures. One of the agencies, the European Food Safety Authority (EFSA), has a prominent role in the composite procedures within the EU pesticide policy - the active substance approval and renewal procedures. These procedures represent the initial steps in the complex administrative process of placing on the market and control of use of plant protection products. The procedures are arranged under the linear risk analysis model within which the scientific risk assessment is performed by Member States and the EFSA, while the political risk management is performed by the Commission and Member States in the comitology procedure. After a brief analysis of the key stages and outcomes of the procedures, the paper discusses two topics. The first relates to the properties of three key aspects of the EFSA's role in the procedures: 1) involvement in adopting guidance documents; 2) publishing appropriate documents and deciding on confidentiality requests; and 3) preparing and submitting the conclusion, its main scientific output related to active substance. The second topic includes five elements of confidence in the EFSA regarding the course and outcome of the procedure: efficiency, independence, transparency, high scientific quality and effective risk communication. The paper discusses the properties of the elements, the main identified challenges associated with them, as well as ongoing and future responses to these challenges, especially those introduced by the Transparency Regulation, adopted in 2019 and applicable from 27 March 2021.

Aviator Xpro EC 225 containing the active substance bixafen was assessed by VKM in spring 2013, and it was concluded that the metabolite M44 has potential for groundwater contamination. Furthermore, VKM assessed in late 2013 the relevance of this metabolite in accordance with the EU guidance document on metabolites in groundwater, and concluded that the malformations observed in rabbits exposed to the metabolite should be considered treatment related. VKM also concluded that the data presented to evaluate the possible genotoxic properties of the metabolite was insufficient to reach a conclusion. Based on this, the Norwegian Food Safety Authority rejected the approval of Aviator Xpro EC 225. The applicant has now submitted results from an in vivo study to strengthen the basis for assessment of genotoxic properties, and also submitted new historical controls in relation to the experimental studies on foetal developmental effects in rabbits. The VKM Panel on Plant Protection Products has discussed the questions raised by The Norwegian Food Safety Authority on the basis of the new data, and has the following opinion: On the assessment of genotoxic properties of the M44 metabolite of bixafen, one of the active ingredients of Aviator Xpro EC 225. It is the view of VKM Panel on Plant Protection Products that the new in vivo mouse micronucleus study, supplemented together with a separate study demonstrating bioavailability, overrides the results of the in vitro clastogenicity studies. Taken together, it is the opinion of VKM that under the conditions studied, M44 should be considered as non-genotoxic. On the assessment of the relevance of the foetal malformations in M44 exposed animals. VKMs Panel on Plant Protection products has assessed the arguments and new historical control data presented by the applicant, intended to show that metabolite M44 is not teratogenic. It is however the opinion of the Panel that the arguments and the new historical data provided by the applicant do not alter the panel’s previous conclusion; that the malformations observed in rabbits exposed to the metabolite M44 should be considered treatment related.

Neem-based products have gained major attention over the last few years due to their wide range of applications in pest management, and have been in the focus of biological plant protection research in the past decade. Yet, there is limited information available to understand the side effects of these neem-derived pesticides on non-target species in soil. Therefore, Porcellionidespruinosus, a terrestrial isopod, was chosen as a non-target species to investigate such possible effects. Two different experiments were conducted to study two different neem-derived plant protection products, i.e., NeemAzal T/S (1% azadirachtin) which is a commercial product registered in the EU, and neem leaf extract from dried neem leaves (1%).The latter simulates the plant protection product, is domestically produced, and widely used by farmers in India and other tropical and subtropical countries. Findings are consistent with previous results obtained with other non-target organisms, i.e., neither of the tested neem products have adverse effects on the mortality of P.pruinosus. However, further research on a wider range of soil organisms is needed to prove the safety of neem-based products as biological control agents and to be part of integrated pest management.
