In the last decade, the impact of needle blight fungal pathogens on the health status of forests in northern Spain has marked a turning point in forest production systems based on species. Dothistroma needle blight caused by and , and brown spot needle blight caused by , coexist in these ecosystems. There is a clear dominance of with respect to the other two pathogens and evidence of sexual reproduction in the area. Understanding spore dispersal dynamics within climatic determinants is necessary to establish more efficient management strategies to increase the sustainability of forest ecosystems. In this study, spore counts of 15 spore traps placed in ecosystems were recorded in 2019 and spore abundance dependency on weather data was analysed using generalised additive models. During the collection period, the model that best fit the number of trapped spores included the daily maximum temperature and daily cumulative precipitation, which was associated to higher spore counts. The presence of conidia was detected from January and maximum peaks of spore dispersal were generally observed from September to November.

First Report of Twig Dieback Caused by on Highbush Blueberry in the Continental United States.

December 2024
Iowa State University, Horticulture, 2206 Osborne Drive, Ames, Iowa, United States, 50011;
Highbush blueberry (Vaccinium corymbosum) is an important fruit crop for pick-your-own agritourism farms in the Midwest. Declining or diseased plants are a major concern for pick-your-own farms, as consumers prioritize healthy plants and organic practices (Norby and Retallick 2012). In August 2023, leaf spot and dieback symptoms were observed sporadically on the current year's growth throughout an organic berry agritourism farm in Eastern Iowa.

Colorado State University, Department of Agricultural Biology, 1177 Campus Delivery, Fort Collins, Colorado, United States, 80523;
Article Synopsis
- Diplodia shoot blight and canker disease (DSB) is caused by the fungal pathogen Diplodia sapinea and primarily affects 2-3 needled pines, such as ponderosa pine, resulting in various symptoms including necrotic needles, cankers, and dieback.
- The pathogen can exist without visible symptoms in trees, making it difficult to detect, and outbreaks are more common in stressed environments like nurseries and seed orchards.
- Although D. sapinea has not been previously reported in Colorado, studies confirmed its presence and pathogenicity after observing symptoms in ponderosa pines in Wyoming in 2018 and discovering symptomatic trees in Colorado in 2021.

Article Synopsis
- Spatholobus suberectus Dunn is a key medicinal plant in China, recognized as the sole source for the herbal medicine Spatholobi caulis in the China Pharmacopeia.
- In November 2023, a leaf disease affected 80% of plants in a plantation in Nanning, characterized by necrotic leaf tips with gray discoloration and brown margins.
- Researchers isolated 36 fungal pathogens from the symptomatic leaves, identifying one specific isolate, YY-3-S, with morphological traits of Diaporthe sp, followed by genetic sequencing for further identification.

Hunan University of Science and Technology, Xiangtan, Hunan, China;
Article Synopsis
- A herb, identified as a perennial, possesses notable medicinal benefits including anticancer and anti-inflammatory properties but faced challenges when leaf blight disease appeared in Xiangtan City, impacting approximately 22% of affected plants.
- The disease symptoms began with water-soaked chlorosis in infected leaves, which progressed to dry yellow shrinkage spreading throughout the plants over a significant planting area of about 30,000 m².
- Researchers identified the disease's causal organisms through a series of laboratory techniques, including surface sterilization, culture on specific agar plates, and molecular identification using gene amplification, with results being deposited in GenBank for further study.

Article Synopsis
- Dothistroma septosporum and Dothistroma pini are harmful pathogens that attack conifers, particularly pine trees, leading to severe damage such as needle loss and tree death.
- A study conducted on various Dothistroma isolates revealed the presence of viral dsRNA segments in some strains, indicating the potential for mycoviruses to help control these pathogens.
- Thirteen new potential viruses were identified, including a range of RNA virus types, with one being a narnavirus specifically associated with D. pini, marking the first virus discovered in this species.
