“…However, these chemical agents have been applied for many years with few little or limited success due to the development of resistance by the fungus (Zamani et al 2006). In addition, the accumulation of hazardous chemicals in the environment raises public concern about their effect on human health and generates environmental concerns mainly due to the carcinogenic and/or teratogenic properties of the compounds as well as their cumulative toxic effects (Thonglem et al 2007;Pimenta et al 2008). In this respect, microbial bio-control agents have shown a great potential as an alternative to synthetic fungicides and offer an environmentally friendly alternative to the use of synthetic pesticides (Kotan et al 2009).…”

“…The pathogen was prepared from approximately 10-day-old cultures grown on PDA medium. The spore suspension containing 1 × 10 5 CFU/ml prepared Glucose Yeast Broth (BYB) was supplemented with 1 ml of Tween 20 (Pimenta et al 2008). The pathogen application was conducted at four different times including simultaneously with the application of bacteria and pathogenic fungi, and the application of pathogenic fungi after 24, 48, and 72 h from the application of bacterial suspension incubated under storage conditions.…”

“…Biological control is becoming an important alternative in the fight against postharvest diseases of fruits and as a result, there is an urgent need for further research in order to develop new and more efficient strategies for bio-control (Pimenta et al 2008). Successful control of infections caused by a number of postharvest pathogens using antagonistic bacteria has been reported on citrus fruits, including Paenibacillus brasilensis, Bacillus subtilis, Burkholderia gladioli pv.…”

Mohammadi P., Tozlu E., Kotan R., Kotan Şenol M. (2017): Potential of some bacteria for biological control of postharvest citrus green mould caused by Penicillium digitatum. Plant Protect. Sci., 53: 134-143.Ten bacteria isolate (4 Bacillus subtilis, 2 Bacillus pumilus, 2 Bacillus cereus, 1 Bacillus megaterium, and 1 agrobacterium radiobacter) were tested in vitro for antagonistic properties against Penicillium digitatum, the causal agent of citrus green mould. The effect of these bacteria was also observed on mycelial growth, spore germination, and spore production of the pathogenic fungus in broth culture. Extracellular enzyme activities of the bacteria were determined. According to the results of in vitro antagonistic tests and enzymes activities, the most promising bacteria were Bacillus subtilis and agrobacterium radiobacter. These bacteria were tested for disease suppression on lemon fruits. In addition, these bacterial isolates also showed remarkable antifungal activity against the pathogen on lemon fruits. The results of this study showed that Bacillus subtilis and agrobacterium radiobacter showed remarkable antifungal activity against the pathogen. Chitinase and glucanase enzyme activity of all the tested bacteria was positive. Protease enzyme activity was positive in all tested bacteria with the exception of agrobacterium radiobacter. In addition, all bacteria inhibited mycelial growth and spore germination (except agrobacterium radiobacter) of the fungus. Bacillus subtilis, Bacillus cereus, and agrobacterium radiobacter inhibited spore production in broth culture. Bacillus subtilis and agrobacterium radiobacter were tested on lemon fruits significantly reduced disease severity. Consequently, these isolates can be used as new biocontrol agents in controlling the post-harvest decay of citrus fruits caused by Penicillium digitatum.

INTRODUÇÃODoenças em pós-colheita reduzem a quantidade e a qualidade de frutos comercializáveis e, em citros, podem provocar grandes perdas. No Brasil, dentre as doenças em pós-colheita dos citros, o bolor verde (Penicillium digitatum) é a principal. Seu controle é realizado com fungicidas, e isolados resistentes do patógeno são relatados (TEIXIDÓ et al., 2001), algumas vezes simultânea a mais de um fungicida (KINAY et al., 2007 RESUMO-O mercado consumidor está exigindo alimentos sem a presença de resíduos de agrotóxicos. Assim, o trabalho teve como objetivo avaliar o controle do bolor verde, em laranjas-Pera, com agentes de biocontrole (Bacillus subtilis e Bacillus licheniformis, Bacillus subtilis (QST 713)), associados ou não ao tratamento térmico. Para tanto, os frutos foram adquiridos em "packinghouse" antes do processamento, sendo lavados e desinfestados com hipoclorito de sódio. Os frutos submetidos a esses tratamentos foram armazenados, por 11 a 28 dias, em temperatura de 10 ºC e UR 90%±5 ou por oito dias a 20 ºC e UR 90%±5. De modo geral, o tratamento térmico reduziu a severidade da doença determinada pela área abaixo da curva do progresso da doença nos frutos e a incidência natural de doenças em pós-colheita de laranja-Pera. Por outro lado, os agentes de biocontrole não controlaram a doença, mostrando que os organismos testados não apresentaram atividade curativa contra o bolor verde. Termos de indexação: Bolor verde, controle biológico, controle físico, citros. POSTHARVEST CONTROL OF Penicillium digitatum IN PERA ORANGE TREES WITH MICROORGANISMS AND HEAT TREATMENTABSTRACT-The consumer market demands food without pesticide residues. Therefore, this study focused on evaluating the control of green mold in Pera orange trees with biocontrol agents (Bacillus subtilis, Bacillus licheniformis and Bacillus subtilis (QST 713)), associated or not with heat treatment. The fruit was obtained in packinghouse before processing, being washed and disinfected with the use of Sodium Hypochlorite. Fruits submitted to these treatments were stored from 11 to 28 days at temperature of 10 ºC and RH 90%±5 or for eight days at 20 ºC and 90%±5. In general, the heat treatment reduced the disease severity determine by the area under the disease progress curve in the fruit and the incidence of natural postharvest disease in Pera oranges. On the other hand, biocontrol agents did not control the disease, showing that the organisms tested did not present curative activity against the green mold.
