Abstract
In Iran, during significant research, the importance of the antagonistic fungus,Talaromyces flavushas been known for the inhibition of the growth of some important plant soil pathogens such asRhizoctonia solani, Verticillium dahliae and Fusarium oxysporum. Also, according to the results of previous studies, preparation of the above-mentioned fungal bioformulations with substrates in the form of different plantresidues such as rice bran, wheat straw and corn wood was possible and using them in the greenhouse and field, in addition to reducing the incidence of the diseases such as the seedling death, Verticillium and Fusarium wilt in cotton, sugar beet, potato, tomato and greenhouse cucumber, increased yield was also observed. 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 with easy applications can greatly affect the attraction of relevant consumers and a successful marketing. 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 theefficacy in biological control of the plant diseases. 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.
