Abstract | Gray mold disease or Botrytis rot, caused by *Botrytis cinerea*, it is well known for significant economic losses in vineyards worldwide, in both yield and quality. Management of gray mold it is traditionally based on fungicide treatments and cultural practices. Fungicide programmes specifically target critical periods during the growing season: late-bloom, bunch closure, veraison and preharvest. However, controlling *Botrytis cinerea* is still a challenge, because the pathogen is able to rapidly develop resistance. Also, more stringent regulations governing fungicide residues have severely restricted chemical control options in conventionally managed vineyards, particularly during the preharvest period. The objective of our study was to assess the potential of an integrated program to reduce Botrytis rot, involving fungicides and biological control agents (BCAs). Two experimental bioproducts were tested: Trichopulvin Td85 25 PU (*Trichoderma koningii* Td85 strain) and Saccharopulvin 25 PU (*Saccharomyces cerevisiae* L30b yeast strain). The efficacy of the proposed integrated program was assessed based on disease incidence and disease severity in field trials, conducted in Tohani vineyards. This integrated strategy that combines fungicides and bioproducts could offer the option to reduce the number of fungicide treatments, thus minimizing the chemical residues, and manage fungicide resistance development.
