A review about antagonistic microorganisms as biocontrol agents, with special emphasis in strawberry

This paper summarizes the data on use of antagonistic microorganisms as biocontrol agents against fungal phytopathogens that affects postharvest fruits and vegetables. The use of synthetic fungicides has been the dominant control strategy for diseases caused by fungi. However, their excessive and inappropriate use in intensive agriculture has created problems that have led to environmental contamination, considerable residues in agricultural products, and phytopathogen resistance. Therefore, there is a need to generate alternatives that are safe, ecological, and economically viable to face this

This paper summarizes the data on use of antagonistic microorganisms as biocontrol agents against?fungal phytopathogens that affects postharvest fruits and vegetables. The use of synthetic fungicides has been the?dominant control strategy for diseases caused by fungi. However, their excessive and inappropriate use in intensive?agriculture has created problems that have led to environmental contamination, considerable residues in?agricultural products, and phytopathogen resistance. Therefore, there is a need to generate alternatives that are?safe, ecological, and economically viable to face this problem. Inhibition of phytopathogen in fruit/vegetable?utilizing antagonistic microorganisms as biological control agents (BCA) could represent a viable and?environmentally safe alternative to synthetic fungicides. ContentsIntroductionPotential action modes of microbial antagonistsMethods of application of antagonistsManagement of diseasesConclusionsReferences The two tables in the paper deal with strawberry. Table 1 is about the use of biocontrol agents on strawberry tissues, in the pre-harvest / post-harvest stages, against Botrytis cinerea and / or Rhizopus stolonifer. Table 2 shows essential oils and plant extracts tested against postharvest diseases of strawberries ?
