Abstract
Abstract Previous domestic and foreign studies have shown the significant effect of Talaromyces flavus on growth inhibition of some important plant pathogens including Verticillium dahliae, Fusarium oxysporum f. sp. lycopersici and Fusarium oxysporum f. sp. cucumerinum. In Iran, it is necessary to produce new formulations of this fungus based on modern technologies given the importance of attracting companies producing biological control agents and transferring the technical knowledge of mass production of formulations of these agents to them. In the present study, based on the method presented in the Pesticide Research Department of the Iranian Plant Protection Research Institute, two types of T. flavus formulations in the form of nano-capsules containing Talaromyces flavus with two forms of powder and suspension were prepared using nanotechnology. In the next step, during the greenhouse examination, the efficiency of each of these new formulations in concentrations of one to five per thousand for soil addition method and concentration of five per thousand for seed impregnation method (six treatments for each of the two new formulations) was compared with the registered formulation of Talaromin in two methods of seed impregnation and soil addition with healthy control and infected control to control cotton Verticillium wilt disease, in the form of a randomized complete block design with 16 treatments and 5 replications. After statistical analysis of the data obtained by Duncan's Multiple Range Test by MS TAT C software, the results showed that in terms of disease severity among treatments with the previous formulation (Talaromin) with each of the methods of soil addition and seed impregnation, there was no statistically significant difference between nano-suspension with each of the concentrations of one, four and five per thousand by the soil addition method and nano-powder with each of the concentrations of two and three per thousand by soil addition method, and the mentioned treatments were included in one statistical group in terms of disease severity with healthy control.
