“…Another study showed that T. atroviride can survive for 45 days on strawberry leaves under greenhouse conditions (25 ± 2 °C, RH = 60 ± 10%) 11 . Furthermore, BCAs (including B. subtilis ) also have been reported to maintain high inoculum on fruit surface during long periods of postharvest storage 34 35 . More successful biocontrol of post-harvest diseases in storage may thus be explained by the fact that the host volume does not change following BCA application and hence there are no new tissues to protect.…”

Using biological control agents (BCAs) is an essential component of integrated pest and diseases management. Despite much research on biocontrol of plant diseases, success in field crops has been limited with most successes being achieved in greenhouse cultivation. This lack of success is often attributed to the complex ecological processes involved in biocontrol. We used next generation sequencing (NGS) technology to study environmental fate of Bacillus subtilis, a widely used BCA, focusing on its dispersal aspect in open field and under protection. The dispersal of B. subtilis was very limited, particularly under protection. The reduction in the BCA population size was relatively small within 8 days; indeed, no overall reduction in the relative abundance was observed under the protected condition. These results suggested that limited dispersal is probably the main reason for its variable (and often low) control efficacy under field conditions. Thus to increase biocontrol efficacy, it is necessary to frequently apply this BCA with the application interval depending on the growth rate of target host tissues. Phyllosphere microbiota differed significantly between plants grown in open field and under protection but were not greatly affected by the introduced BCA.

“…Any effect of BCAs on controlling grey mould diseases cannot be solely accessed by evaluating the composition of microbial communities on the respective fruits. Some reports showed that the abundance of bacterial communities was correlated with the efficacy of BCAs originating from different Bacillus species to control grey mould of strawberry (Berg, ; Wei et al., ) and anthracnose disease of papaya fruit (Hasan, Mahmud, Ding, & Kadir, ). In another scenario (Sylla et al., ), the effect of Boni on fungal composition and diversity in strawberry leaves was also reported.…”

Fruit grey mould, caused by the fungus Botrytis cinerea, is known to be a harmful disease of strawberry at postharvest stage. However, effects of an application of biological control agents (BCAs) on strawberry fruit in terms of shift in the microbial community are still unknown. The present research aimed to investigate the effects of an application of BCAs on postharvest microbial populations present on strawberry fruits. Strawberry plants were sprayed with three kinds of BCA, RhizoVital 42 fl. (Bacillus amyloliquefaciens FZB42), Trianum‐P (Trichoderma harzianum T22) and Naturalis (Beauveria bassiana ATCC 74040), targeting Botrytis cinerea fungus. Control plots were composed of water and fungicide treatments. Microbial communities (bacteria and fungi) were analysed via next‐generation sequencing on an Illumina MiSeq. Analysis of 16S RNA and ITS rRNA sequences indicated that the BCAs application modified both bacterial and fungal community compositions and diversity. An application of two BCAs together had more effects on microbial community composition than a single application. These results suggest that BCAs can modify bacterial and fungal community composition and diversity on strawberry fruits, which may consequently improve the efficiency and establishment of these products on control of postharvest diseases of fruits, such as grey mould.

“…С другой стороны, преимущество использования бактериальных биоагентов в том, что они могут размножаться и распространяться на новые ткани растения и, следовательно, требуют меньшего применения, чем синтетические фунгициды [2]. Кроме того, сообщается, что биоагенты (включая B. subtilis) также поддерживают высокий уровень инокулята на поверхности плодов в течение длительных периодов хранения после сбора урожая [10,11].…”

М» (2 л/га) после цветения на фоне двух стандартных обработок фунгицидом «Луна Транквилити», КС (125 + 375 г/л) (до цветения) эффективно снижает поражение ягод земляники серой гнилью. Две обработки после цветения «Фитовермом М», Ж (2 л/га), и «Алирином Б», СП (60 г/ га), в условиях жаркого и сухого лета эффективно снижают гнили ягод (БЭ = 75,8-88,2 %) без применения синтетических фунгицидов. Ключевые слова: земляника, серая гниль, биофунгициды, Bacillus subtilisis, концепция «антагонистического замещения» Summary. Research conducted in the 2016-2018, showed that the use of Fitoverm M (2 l/ha) after flowering against the background of two standard treatments with the fungicide Luna Tranquility, CS (125 + 375 g/l) (before flowering) effectively reduces the damage of strawberries to gray mold. Two treatments after flowering with Fitoverm M, F (1.5 l/ha) and Alirin-B, SP (60 g/ha) in hot and dry summer conditions effectively reduce the berries rot (BE = 75.8-88.2%) without use of synthetic fungicides.
