Apple Proliferation Epidemics Detected in Scab‐Resistant Apple Trees
Journal of Phytopathology, 1995AbstractIn the Friuli‐Venezia Giulia, a region of Italy, where serious epidemics of apple proliferation (AP) are known to occur, varieties resistant to scab (Venturia inaequalis (Cke.) Wint.) are increasingly being used in new orchards. The most important cvs are Florina. Prima and Priscilla. These varieties were cultivated according to organic farming

SOME EXPERIENCES IN CONTROL OF APPLE SCAB IN SERBIA
Acta Horticulturae, 2013Apple scab caused by Venturia inaequalis (Cooke) G. Winter is recognized as the most important disease of apples in Serbia. Fungicides remain the primary tool for managing this disease and, due to its polycyclic nature; repeated applications are required over the course of a single season.

Apple Scab: Resistance to Chemical Fungicides
Biology Bulletin ReviewsThe review highlights the situation with the development of resistance to various systemic fungicides in Venturia inaequalis around the world and in Russia, with an assessment of the prospects for their further use. Information is provided on all fungicides used in Russia against apple scab, their effectiveness at a given time, and a description of ...

Use of the A-scab model for rational control of apple scab [PDF]
, 2010 A-scab is a dynamic model for Venturia inaequalis primary infections. It simulates ascospore maturation, ejection, deposition, and infection during the season based on hourly data of air temperature, rainfall, relative humidity, and wetness duration. A-scab produces a risk index for each infection period and predicts the time of disease onset.

Apple scab caused by the fungus Venturia inaequalis (Cke.) Wint. is a destructive disease of apple. The pathogen is a facultative saprophyte that grows subcuticularly on the host. V. inaequalis must obtain nutrients through an active means. The fungus grows as a stroma of thick-walled cells between the cuticle and the outer wall of the host epidermis ...

Glasshouse experiments on apple scab
Annals of Applied Biology, 1967SUMMARYExperiments with fungicide mixtures used protectively and curatively against apple scab showed no advantage from adding phenylmercury chloride (PMC) to certain protective fungicides. Sulphur fungicides greatly impaired the curative activity of PMC, especially in mixtures applied 24 hr. after infection, but captan showed little and dodine acetate

Glasshouse experiments on apple scab
Annals of Applied Biology, 1966SUMMARYDilutions of various fungicides were compared on potted MM 109 clonal rootstocks in the glasshouse for protective (pre‐infection) and curative (post‐infection) activity against apple scab. The materials, as commercial preparations, included captan, copper (as ‘dry’ Bordeaux mixture), dichlofluanid, didecyldimethylammonium bromide (DDAB ...
