Fungal diseases are one of the most important causes that drastically reduce the agricultural crop production worldwide, for which synthetic fungicides are the major means of control. The excessive use of fungicides causes environmental pollution, toxicity to human beings, besides the development of fungicide-resistance in these phytopathogens [1]. Toward this endeavor, an eco-friendly way to reduce the agricultural losses is to use microbes, as biocontrol agents, which is simple, cost–effective and user friendly. In this context, cyanobacteria are one of the possible candidates because of their promise as a biofertilizer and ability to produce a diverse range of bioactive metabolites [2], [3], [4], [5] and [6].
