Résumé en langage clair
The two biocontrol strains, P. fluorescens strain 4-6 and strain 1-112 were tested alone or together, or in combination with commercially registered fungicides, MERTECT (Thiabendazole) or SCHOLAR (Fludioxonil) for the control against gray mold in ‘Empire’ apples. The two biocontrol strains, P. fluorescens strain 4-6 and strain 1-112, when treated alone had the next highest gray mold incidence. The combination of two antagonist strains, P. fluorescens strain 4-6 and strain 1-112, treatment had significantly lower gray mold disease incidence than that of either of the strains. All the combination treatments with the antagonist, P. fluorescens strain 4-6 or strain 1-112, and half rate of the commercially recommended rates of the chemical fungicides MERTECT (Thiabendazole) or SCHOLAR (Fludioxonil ) had complete control of gray mold up to 115 days in cold storage and in the subsequent shelf-life study. The positive chemical fungicide controls, MERTECT or SCHOLAR also had complete control of gray mold.
