“…Similar variation was observed in response of Pinus families to Fusarium circinatum (Roux et al, ), and clones of Ulmus americana L. (American elm) to Ophiostoma ulmi (Buism) (Tchernoff, ). Jankowiak, Banach, and Balonek () reported similar response of Quercus robur L. (pedunculate oak) families to Phytophthora cambivora (Petri) Buisman. Current screening trials show that there is significant potential for selecting PD tolerant P. taeda from current southeastern U.S. planting stock.…”

We examined intraspecific and inter‐year variation in tolerance of Pinus taeda to two ophiostomatoid fungi, Leptographium terebrantis and Grosmannia huntii. Containerized seedlings of P. taeda from 27, 32, 17 and 23 different elite genetic families were artificially inoculated with L. terebrantis and G. huntii in years 2013, 2014, 2016 and 2017, respectively. Six connector families were inoculated every year. Eight weeks post‐inoculation, lesion and occlusion were measured on each seedling to determine the relative susceptibility/tolerance of families to these fungi. Pinus taeda families widely differed in these parameters suggesting intraspecific variation in the susceptibility/tolerance to the inoculated pathogens. The overall tolerance of the connector families to these fungi varied among the experimental years. These results showed that intraspecific variation to L. terebrantis and G. huntii exists among P. taeda families and it could be possible to select tolerant families to minimize the potential impact due to these fungi.

“…Previous research into fungal colonisation of oak stands has revealed that the greatest losses are caused by pathogens of the genus Phytophthora (Rizzo et al 2002;Oszako 2005;Oszako et al 2007;McPherson et al 2013;Scanu et al 2013). In Poland, oak trees have been colonised mainly by Phytophthora quercina, Phy tophthora cactorum, Phytophthora plurivora, Phytoph thora cambivora and Phytophthora cinnamomi which are largely responsible for root diseases (Orlikowski et al 2011;Jankowiak et al 2013;Nowakowska et al 2016). Trees become more susceptible to Phytophthora pathogens under water stress conditions (Oszako and Orlikowski 2005).…”

Fungi colonising oak seedlings in forest plantations in north-eastern Poland were identified in 2014-2015. The evaluated 4- to 6-year bare root oaks originated from the Olsztynek Forest District (Regional Directorate of the State Forests in Olsztyn). In total, 744 fungal isolates belonging to 11 different species, and 11 genera, were identified in tested plants. Amongst them, 186 cultures (25%) were classified as plant pathogens. The most commonly isolated pathogenic fungi belonged to the Fusarium and Cylindrocarpon genera.

“…Increased populations of geometer moths were observed in Poland in the years 2011-2013, more than ever in the north-eastern regions of the country. Organisms that damage the fine roots of deciduous trees, especially oaks, are pathogens of the genus Phytophtora and Pythium (Jankowiak et al 2013). Oak decline has also been observed in Western Poland for many decades (Oszako 2007) -recently in the year 2015.…”

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.
