THE APPLICATION OF NANOTECHNOLOGY IN DEVELOPING TALAROMYCES FLAVUS FORMULATIONS

In Iran, during significant research, the importance of the antagonistic fungus, Talaromyces flavus has been known for the inhibition of the growth of some important plant soil pathogens. According to the results obtained to this stage of the research, the commercialization of the bioformulation of this fungus is of particular importance. Since the marketing is considered as one of the important factors for the continuation of commercialization, considering the type of bioformulation specifically nanoformulations with easy applications can greatly affect the attraction of relevant consumers and a successful marketing. The main objective of this research is increasing the stability of T. flavus using the preparation of the effective nanoformulations containing T. flavus that it can be applied in controlling plant diseases in future. In this research, four nanoformulations (two nanocapsules, one nanoemulsion and one nanopowder) containing Talaromyces flavus were prepared. For preparation these nanoformulations, the polymerization method was used. In this method, the organic phase, including plant oil and the fungal biological agent was added to the aqueous phase, including several hydrophilic monopolymers such as poly urea formaldehyde, chitosan and starch. In the next step, the cross link polyureaformaldehydekers such as calcium chloride and surfactant were added to all two phases and homogenization was carried out by homogenizer in 350C and 10000 rpm. In this study, nanoformulations were prepared in two types: nanocapsule (F1 and F3), a type of nanoemulsion (F2), and a type of powder nanoformulation (F4) of T. flavus. Therefore, in light of the recent advances in the application of nanotechnology in various sciences, it seems necessary to prepare different nanoformulations of the above biological agent with an emphasis on the ease of use, and study the efficacy in biological control of the plant diseases.
