Laboratory effect of Boni Protect containing Aureobasidium pullulans (de Bary) Arnoud in the control of some fungal diseases of apple fruit

Abstract

The efficacy of <em>Aureobasidium pullulans </em>(in the biopreparation Boni Protect) against different pathogens of apples (<em>Botrytis cinerea, Monilinia fructigena, Penicillium expansum, </em>and <em>Pezicula malicorticis</em>) was evaluated under laboratory con- ditions. The biocontrol product was applied at concentrations of 0.05%, 0.1%, and 0.5%. Fruits of apple cultivars 'Jonagold Decosta' and 'Pinova' were used. Boni Protect was very effective against <em>B. cinerea </em>on cv. 'Jonagold Decosta', reducing disease incidence by 55–83.8%. On 'Pinova' apples, this biological control product was the most efficient at earlier stages of the experiment. It inhibited grey mold by 65% after 5 days from inoculation and only by 14% after 20 days. On cv. 'Jonagold Decosta', Boni Protect at a concentration of 0.1% was also effective against <em>M. fructigena</em>, reducing brown rot by 31.4–74.5%, but its efficiency on cv. 'Pinova' was not significant. Blue mold caused by <em>P. expansum </em>was inhibited only slightly by the biocontrol product, while <em>P. malicorticis </em>proved to be the most resistant to its antagonistic abilities

Yeasts from native Brazilian Cerrado plants: Occurrence, diversity and use in the biocontrol of citrus green mould

“…However, when the apples were inoculated by P. expansum, the differences between the treatments and controls were much smaller than in combinations with B. cinerea and M. fructigena. The development of Penicillium rot was lightly inhibited and only at the beginning of the experiment (Wagner et al 2012). These results are similar to results found in this work.…”

Biocontrol Activity of Aureubasidium pullulans and Candida orthopsilosis Isolated from Tectona grandis L. Phylloplane against Aspergillus sp. in Post-Harvested Citrus Fruit

“…There have been no reports of A.namibiae as a potential biocontrol agent for destructive moulds. Meanwhile, A.pullulans are antagonistic yeasts that are used as biocontrol agents for destructive moulds on postharvest fruits and vegetables [32,33] and have been used as commercial products originating from Germany with the name Boni Protect [34]. The antagonism properties of A. pullulans are utilized as biocontrol agents because of their antifungal active compounds, namely, aureobasidin A [32].…”

Effect of Some Biopreparations on Health Status of Strawberry (Fragaria ananassa Duch.)

“…The development of Aureobasidium pullulans depends on many factors, such as the temperature, pH and the content of nutrients in the substrate. The efficacy of the fungus was reported by many authors [30][31][32][33][34]. The effectiveness of the antagonist may be attributed to nutrient competition, competition for space, direct parasitism, production of enzymes and induced resistance [35].…”
