Dieback of Fraxinus excelsior [PDF]
, 2013 Ash dieback caused by Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea) is a disease that has emerged during the past twenty years. It was first observed in Poland and has expanded over most of the distribution area of European ash (Fraxinus excelsior) in Europe. This thesis comprises four scientific papers.

Drone‐based phenotyping of maize for multiple disease resistance and yield in breeding field trials
The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Improving selection for multiple disease resistance (MDR) and yield in maize (Zea mays L.) requires high‐throughput, objective phenotyping tools, particularly under field conditions where several foliar diseases co‐occur. We evaluated drone‐based multispectral vegetation indices (VIs) for predicting resistance to northern leaf blight (NLB ...

Occurrence of Phytophthora citrophthora on Syringa vulgaris in Poland
Acta Mycologica, 2014 Phytophora citrophora was isolated from dieback shoots, base of diseascd stems and top parts of lilac plants during 3 vegetation periods. The species was detected from about 75% of analysed plant parts.

Forest Pathology, Volume 56, Issue 5, October 2026.ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

Evidence from mortality dating of Fraxinus excelsior indicates ash dieback (Hymenoscyphus fraxineus) was active in England in 2004-2005 [PDF]
, 2018 Ash (Fraxinus excelsior L.) planted at six sites over the past 20 years was investigated. Three geographically isolated sites (Northumberland, Leicestershire and Devon) were compared with three sites in established areas of ash dieback in East Anglia ...

Are novel and co‐xenic associations common in alien fungal and fungus‐like plant pathogens?
New Phytologist, Volume 252, Issue 2, Page 843-860, October 2026.Possible scenarios for plant–pathogen associations during invasion. An introduced plant may occur in a new area without its pathogen (enemy release) or together with its pathogen (co‐introduction). The presence of the alien plant (in red) and its co‐introduced pathogen (in dark red) can result in pathogen spillover to co‐occurring plants. Host jumps to

Outbreaks of Yuzu Dieback in Goheung Area: Possible Causes Deduced from Weather Extremes
The Plant Pathology Journal, 2015 Starting in 2012, severe diebacks usually accompanied by abundant gum exudation have occurred on yuzu trees in Goheung-gun, Jeonnam Province, where severely affected trees were occasionally killed.

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract We studied the impacts of uncrewed aerial vehicle (UAV)‐applied triclopyr + fluroxypyr on rangeland weeds and other forbs in native tallgrass prairie. Two rates were tested: high (0.63 kg ae ha−1 triclopyr + 0.21 kg ae ha−1 fluroxypyr) and low (0.21 kg ae ha−1 triclopyr + 0.07 kg ae ha−1 fluroxypyr).

Landscape-scale assessment of tree crown dieback following extreme drought and heat in a Mediterranean eucalypt forest ecosystem [PDF]
, 2013 Mediterranean regions are under increasing pressure from global climate changes. Many have experienced more frequent extreme weather events such as droughts and heatwaves, which have severe implications for the persistence of forest ecosystems.
