Sensitivity of Venturia inaequalis to trifloxystrobin

Pest Management Science, 2002
Abstract The sensitivity of Venturia inaequalis to trifloxystrobin was monitored by both in vitro (spore germination) and in vivo tests (on apple seedlings).

Resistance in Malus to Venturia Inaequalis

Annual Review of Phytopathology, 1969
INTRODUCTION Scab, caused by Venturia inaequalis (eke .) Wint., has been one of the most serious and difficult diseases of apple to control. Because of the neces­ sity of careful timing of application and difficulty in eradication, fungicides are frequently not effective.

Melanoprotein and virulence determinants of Venturia inaequalis

Physiological Plant Pathology, 1984
Abstract The capacity of the melanoprotein produced in culture by a virulent isolate of Venturia inaequalis to increase the number of lesions on inoculated plants, was not significantly reduced by treatment with iron salts. Iron was tightly bound by the melanoprotein, in contrast with calcium and magnesium which were removed from mixtures by ...

POLYMORPHISM OF APPLE SCAB VENTURIA INAEQUALIS IN BELARUS

Молекулярная и прикладная генетика, 2021
Study of Venturia inaequalis (Cooke) Wint. polymorphism causing apple scab is due to the need to elaborate and implement breeding programs allowing to develop highly resistant apple varieties and systems of phytosanitary protection against the pathogen.

A PROPOSAL FOR THE NOMENCLATURE OF VENTURIA INAEQUALIS RACES

Acta Horticulturae, 2009
The Venturia inaequalis-Malus pathosystem was one of the first for which gene-for-gene relationships were demonstrated following the discovery of such relationships between Melampsora lini and flax by Flor in the 1950s. An understanding of these relationships forms the basis for monitoring pathotypes of V.

CYTOLOGICAL STUDIES OF VENTURIA INAEQUALIS

Canadian Journal of Botany, 1958
A cytological study of Venturia inaequalis has revealed that only one meiosis occurs in the ascus, and that the haploid number of chromosomes is seven. Most asci originate through typical hooks, but in a number of perithecia these croziers are absent, and large budding cells give rise to small ascus-shaped structures.

VARIABILITY OF THE PATHOGENICITY OF VENTURIA INAEQUALIS IN EUROPE

Acta Horticulturae, 2004
In the frame of the DARE (Durable Apple Resistance in Europe) project, a collection of strains of Venturia inaequalis was established. It comprises 319 strains from 8 European countries, isolated from 48 different Malus species and M. x domestica cultivars. The pathogenicity of 39 strains from this collection was tested on a set of 8 differential hosts,

Eradication of Venturia inaequalis (Cooke) Wint.

Nature, 1954
THE control of apple scab or black spot, caused by Venturia inaequalis, using protective and eradicant protective spray programmes during the parasitic phase of fungal activity has reached a stage beyond which further substantial improvement is unlikely.

PHYSIOLOGICAL RACES OF VENTURIA INAEQUALIS

Canadian Journal of Plant Science, 1957
Cultures of Venturia inaequalis were isolated from infected apple leaves and fruits received from various parts of Canada. The isolates differed in their ability to produce spores and to a certain extent in their growth. Variations were observed among monoconidial isolates obtained from a tissue isolate. Monoconidial cultures from an isolate varied in
