How safe are peat‐free growing media? An exploration of plant pathogen risks to the horticultural industry and recommendations for risk mitigation

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1684-1699, November 2025.
The UK's horticultural industry is shifting from reliance on unsustainable peat‐based growing media to products that contain alternative constituents, including coir, bark, wood fibre and composted green waste. Some peat‐alternatives carry an elevated risk of harbouring plant pathogens, including the potential to introduce novel pathogens from overseas,

What Risk Does Phytophthora ramorum Pose to Sitka Spruce (Picea sitchensis) and Other Conifers in Britain?

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Larch (Larix) and, to a lesser extent, rhododendron (Rhododendron ponticum) have emerged as key drivers of the Phytophthora ramorum epidemic in Britain because of the copious numbers of sporangia that are released from their foliage following infection; the inoculum then initiates stem and foliar infections on nearby broadleaf and conifer ...

Outbreak of Phytophthora abietivora in a Québec Forest Nursery: Emergence of a New Phytophthora Tree Pathogen?

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Tree nurseries play a key role in the Canadian economy and reforestation efforts, producing over 600 million seedlings annually. Despite rigorous management practices, nurseries are not exempt from pathogen outbreaks, which can be devastating on many levels.

Early warning signals in plant disease outbreaks [PDF]

, 2018
Infectious disease outbreaks in plants threaten ecosystems, agricultural crops and food trade. Currently, several fungal diseases are affecting forests worldwide, posing a major risk to tree species, habitats and consequently ecosystem decay.

Potential impacts of plant pests and diseases on trees and forests in the United Kingdom

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1538-1550, September 2025.
The UK Plant Health Risk Register (PHRR) has so far identified 581 Plant Pests and Diseases (PPDs) that could invade the United Kingdom and affect 74 tree species. The combined effects of multiple invasions on trees are little understood and seldom considered.

Loss of dominant tree‐mycorrhizal mutualism increases soil fungal diversity and alters community structure

Functional Ecology, Volume 39, Issue 9, Page 2425-2436, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Due to their mutualistic partnership with trees, mycorrhizal fungi are often important components of soil microbial communities. Mortality of tree hosts can have dramatic effects on mycorrhizal populations, but how these shifts impact the remaining soil microbial ...
