During 25 surveys of global Phytophthora diversity, conducted between 1998 and 2020, 43
new species were detected in natural ecosystems and, occasionally, in nurseries and …

Phytophthora nicotianae was first isolated from tobacco at the end of the 19th century. This
organism is now considered as one of the most devastating oomycete plant pathogens, with …

Phytophthora spp. cause major losses in the nursery industry worldwide. However, a clear
demonstration of the route of movement has not been previously shown. A survey of 10 …

Nursery plants are important vectors for plant pathogens. Understanding what pathogens
occur in nurseries in different production stages can be useful to the development of …

Between 2010 and 2015, an extensive survey of Phytophthora diversity was performed
across Portugal. Baiting and direct isolation tests obtained 48 Phytophthora taxa in 62 of 70 …

The genetic diversity of Phytophthora spp. was investigated in potted ornamental and fruit
tree species. A metabarcoding approach was used, based on a semi‐nested PCR with …

The plant nursery industry has become an ideal reservoir for Phytophthora species and
other soilborne pathogens. In this context, isolation from tissues and soil of ornamental and …

A dieback was observed on three-year-old pot-grown plants of Cycas revoluta in Sicily
(Italy). Symptoms, including stunting, yellowing and blight of the leaf crown, root rot and …

A metabarcoding method based on genus-specific primers and 454 pyrosequencing was
utilized to investigate the genetic diversity of Phytophthora spp. in soil and root samples of …

This report investigates population structure and genetic variability of Phytophthora spp.
isolated from botanically diverse plants in Florida. Internal transcribed spacer-based …
