Abstract :
Crown and root rot disease caused by different species of Phytophtera is one of the most important pistachio diseases. Although various methods have been recommended for the management of this disease, biological control has been considered as an environmentally compatible method. In this research, the antagonistic effect of 3 bacterial strains isolated from the soils of Rafsanjan city on Phytophthoradrechsleri was investigated in laboratory conditions. Isolates 216, 217, 226 showed the highest inhibition halo with 7.5 and 5.5 mm, respectively. and hydrogen cyanide, the ability to colonize the root and a number of other tests were performed. Finally, the effect of these isolates in the control of the pathogenic oomycetes was measured in the pistachio plant laboratory conditions, and the results were indicative of the control of pathogenic damage in the target traits by these isolates. It is hoped that the selected isolates of this test will be monitored by other researchers and according to their appropriate potential, they will advance to the stages of commercialization or the use of suitable genes for the production of disease-resistant transgenic plants.
