Selection and orchard testing of antagonists suppressing conidia production of the apple scab pathogen Venturia inaequalis [PDF]

, 2009
Apple scab caused by Venturia inaequalis is a major disease in apple production. Epidemics in spring are initiated by ascospores produced on overwintering leaves whereas epidemics during summer are driven by conidia produced on apple leaves by biotrophic

The Nutritional Requirements of Venturia inaequalis [PDF]

Journal of General Microbiology, 1955
A study of the nutritional requirements of Venturia inaequalis showed that this parasitic fungus grew well in a medium containing: K2HPO4, 0·004M; MgSO4.7H2O, 0·002M; NH4NO3, 0·0375M; glucose 4% (w/v); Zn and Mn 2 p.p.m.; thiamine, pyridoxine, nicotinic acid, folic acid, ascorbic acid.

Further Nutritional Studies of Venturia inaequalis [PDF]

Journal of General Microbiology, 1955
Summary: A series of nutritional experiments was carried out on cultures from single ascospores isolated from a single ascus of Venturia inaequalis. The results showed: (a) thiamine stimulated all cultures and other vitamins did so to a much less extent; (b) decoctions of apple leaves contained stimulatory substances; (c) these substances were amino ...

Phenotypic and transcriptomic analyses reveal major differences between apple and pear scab nonhost resistance

Peer Community Journal, 2023
Nonhost resistance is the outcome of most plant/pathogen interactions, but it has rarely been described in Rosaceous fruit species. Apple (Malus x domestica Borkh.) have a nonhost resistance to Venturia pyrina, the scab species attacking European pear ...

Leaf shredding as an alternative strategy for managing apple scab resistance to demethylation inhibitor fungicides

Frontiers in Horticulture, 2023
Within integrated apple scab control there is a strong focus on reduction of Venturia inaequalis primary inoculum. The hypothesis that leaf shredding as an orchard sanitation practice would reduce the effective population size of the fungus (resulting in

Welcome Pathogens: Transient Heat Dampens Immune Responses to Acibenzolar-S-Methyl in Apple Plants. [PDF]

Plant Cell Environ
ABSTRACT Climate change affects plant‐pathogen interactions, with disease outcome varying depending on the pathosystem and environmental scenario. In Arabidopsis, a thermo‐sensitive module of salicylic acid (SA) signalling makes immunity vulnerable to heat.
