“…For bunches of 'Benitaka' and 'Italia' table grapes inoculated with B. cinerea conidial suspensions, Youssef and Roberto [18,19] reported gray mold incidence values close to 15 and 25%, respectively, after 30 days of cold storage. Moreover, for 'BRS Vitoria' table grapes inoculated under similar conditions, the gray mold incidence observed was higher than 40% [10].…”

“…For example, treatments with salt solutions such as potassium bicarbonate have been recommended for inhibiting gray mold in 'Italia' and 'Benitaka' table grapes [18,19], as well as cold storage combined with sulfur dioxide (SO 2 ) [10,[20][21][22][23].…”

Cold Storage and Biocontrol Agents to Extend the Storage Period of ‘BRS Isis’ Seedless Table Grapes

'BRS Isis' is a novel hybrid seedless table grape with large reddish bunches. This cultivar is cultivated in tropical and subtropical areas and has potential to be exported overseas; however, under these growth conditions, grapes can be severely damaged by gray mold (Botrytis cinerea), the main postharvest disease of table grapes. Thus, this study aimed to evaluate different pre-and postharvest strategies to extend the storage period of 'BRS Isis' seedless table grapes. The treatments consisted of grapes packed into carton boxes under cold storage (1 • C and high relative humidity), pre-and/or postharvest treatment with potassium bicarbonate or a biological control agent (Bacillus subtilis), all with Botrytis inoculation. Additionally, two controls, with and without Botrytis inoculation, were also evaluated. The experimental design was completely randomized with eight treatments and three replications, and each plot consisted of four bunches. After a 50-day cold storage period, the carton boxes were kept for five days at room temperature (22 • C). Gray mold incidence and water loss, as well as soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, and color attributes were evaluated during both periods. Cold storage effectively reduced gray mold in 'BRS Isis' seedless grape for a period of 50 days, even when grapes were inoculated; however, no difference among treatments was observed. Higher water loss was observed in both non-treated control treatments.

“…Naradisorn et al (2006) showed that treatment of strawberry plants with calcium chloride resulted in firmer fruits than those untreated. Youssef and Roberto (2014) tested different types of calcium salts on pre-harvest, post-harvest, and a combination of pre and post-harvest 'Italia' grape, and found that the salts significantly reduced the incidence of gray mold caused by Botrytis cinerea. This could possibly be explained by the different roles played by calcium in plant tissues, especially on the protection of membranes and cell walls as well as on the elicitation of responses to biotic or abiotic stresses (CHITARRA, 2006).…”

“…In order to reduce the significant losses caused by post-harvest rots, fungicides such as imazalil, thiabendazole, and prochloraz, are still intensively used (BRASIL, 2016). Nevertheless, the use of phosphites in fruit and vegetables in the post-harvest stage has become a common alternative to the use of fungicides, because these salts exhibit antifungal activity and have no grace period, therefore representing a control tool in the disease management (MILLER et al, 2006;DELIOPOULUS;KETTLEWELL;HARE, 2010;CERIONI et al, 2013;ALEXANDRE et al, 2014;YOUSSEF;ROBERTO, 2014). According to Buffara et al (2013), phosphites exhibit a systemic mode of action, apo-symplastic movement, low toxicity, low cost, and act directly on the fungi.…”

-The aim of this study was to evaluate the frequency of quiescent fungi and the effect of phosphites under modified atmosphere on Lasiodiplodia theobromae in papaya. The fruits were treated with a range of doses of phosphites and their actions evaluated under conditions of ambient and modified atmosphere. Of the eight fungal genera found, Lasiodiplodia was the most common. No interaction was observed between the evaluated factors and only atmosphere and dose were independently significant. The usage of phosphites and modified atmosphere reduced the severity of the disease, and did not affect the chemical properties of the fruits.Keywords: Carica papaya. Alternative control. Phosphites. Post-harvest quality. FREQUÊNCIA DE FUNGOS QUIESCENTES E MANEJO ALTERNATIVO DA PODRIDÃO PEDUNCULAR EM MAMÃO NA PÓS-COLHEITARESUMO -O objetivo deste trabalho foi avaliar a frequência de fungos quiescentes e o efeito de fosfitos sob atmosfera modificada sobre Lasiodiplodia theobromae em mamões. Os frutos foram tratados com várias doses de fosfitos e suas ações foram avaliadas em condições de atmosfera ambiente e atmosfera modificada. Dos oito gêneros fúngicos encontrados, Lasiodiplodia sp. foi mais frequente. Não houve interação entre os fatores avaliados e apenas os fatores atmosfera e dose independentemente foram significativos. O uso de fosfitos e atmosfera modificada reduziram a severidade da doença e não alteraram os atributos químicos dos frutos.Palavras-chave: Carica papaya. Controle alternativo. Fosfitos.
