Survey for Phytophthora fragariae var. fragariae in Finland

Abstract

A survey for the possible occurrence of red‐core disease (Phytophthora fragariae var. fragariae) was carried out on 250 strawberry production sites in Finland. The fields were inspected visually. A total of 1080 samples of strawberry roots were taken in spring and autumn 1995 and examined visually, microscopically and by isolation in the laboratory. Root‐tip bait‐plant tests were performed in the glasshouse to look for the latent presence of the fungus. No red‐core disease was detected in any of the inspected fields or in the examined samples.

Development and evaluation of a recombinase polymerase amplification assay for rapid detection of strawberry red stele pathogen

“…P. fragariae was not present in Finland according to the EPPO/ CABI, 1997. The absence of the pathogen was also confirmed by the countrywide survey for red-stele disease conducted on strawberry roots collected in 1995 (Pohto 1999). However, in 2012 EVIRA (Finnish Food Safety Authority) surprisingly detected P. fragariae for the first time among 55 of the strawberry plantations collected from outdoor horticultural production in different regions of Finland (EVIRA 2013).…”

Searching for New Beneficial Bacterial Isolates of Wild Raspberries for Biocontrol of Phytopathogens-Antagonistic Properties and Functional Characterization

“…are just examples of the most symptomatic microorganisms that can cause plant diseases in the organic production of soft fruits including raspberries [ 1 ]. Phytophthora genus belongs to a common pathogens of raspberry and is one of the most crucial dangers in organic farming [ 2 ]. Research shows that representatives of the Colletotrichum genus can survive in soil and in any remaining plant residues for up to 30 months which might lead to re-infection even after defeating the disease in a particular growing season [ 3 ].…”
