Grey mould incidence is reduced on grapevines with lower vegetative and reproductive growth
The hypothesis that grey mould incidence would be positively correlated to grapevine canopy development was confirmed over a period of 3 years (2004–2006) on Aranel cultivar in an experimental vineyard near Montpellier, south France, evidenced that unfavourable climatic conditions for the disease development can be counterbalanced by conditions of high vine growth and associated canopy and cluster features.

The structural and biochemical changes during grape berry development which account potentially for the onset and increase in susceptibility to Botrytis cinerea are investigated and a very close connection between fruit susceptibility and the level of fruit maturity is identified.
Modes of action for biological control of Botrytis cinerea by antagonistic bacteria
This review focuses on various bacteria that act as biological control agents of B. cinerea and their associated mechanisms, and discusses the advantages and drawbacks of MoA for future applications of bacteria in the field and in post-harvest storage, as well as combination of different MoAs as a strategy to achieve a more regular efficacy.
Environmental Conditions Affect Botrytis cinerea Infection of Mature Grape Berries More Than the Strain or Transposon Genotype.
The data collectively showed that T and RH or WD were more important than strain for mature berry infection by either mycelium or conidia and the effect of the environment on the different strains was similar.

Analysis of population subdivision in the multihost fungus Botrytis cinerea based on comprehensive multiyear sampling on different hosts in three French regions revealed a weak association between population structure and geography, but a clear differentiation according to the host plant of origin.

The study validates a laboratory pre-selection process followed by a field screening step, resulting in a candidate B. ginsengihumi strain S38 with a high potential for BBR biocontrol and future development in vineyards.
Analysis of the Molecular Dialogue Between Gray Mold (Botrytis cinerea) and Grapevine (Vitis vinifera) Reveals a Clear Shift in Defense Mechanisms During Berry Ripening.

Analysis of the pathogen and the host to investigate the infection process developed by B. cinerea on MB versus VB, and the plant defense mechanisms deployed to stop the fungus spreading revealed a defense pathway switch during berry ripening.
Multi-organ screening of efficient bacterial control agents against two major pathogens of grapevine
Marked differences between the two fungal pathogen species in terms of strain inhibitory efficacy were observed on wounded berries, as some Bacillus spp.
