The study of isolation and diagnosis of the bacteria causing coronary tuberculosis on Eucalyptus camaldulensis Dehn has taken place in the great hall of the Faculty of Agriculture – University of Kerbala. In a number of nurseries for some of the central Euphrates provinces and methods of combating them, the thesis presented by the student (Jassim Abdul Hurr Sajad, from the Plant Protection Department, aims at studying the isolation and diagnosis of the bacteria causing this disease in some provinces of the Middle Euphrates with testing the sensitivity of some eucalyptus varieties in addition to evaluating the nano zinc oxide compound and comparing it with non-nano zinc oxide and the possibility of using the fungal biological agents Trichoderma harzianum and Trichoderma atroviride and the bacterial biological agent Bacillus thuringiensis, as well as the use of the two chemical pesticides Platanol and Nordex in disease resistance.
The thesis indicates through discussion to the spread of coronary tuberculosis disease in some governorates and the percentage and severity of infection were determined, as well as the microstructure and phenotypic characteristics, biochemical tests and molecular diagnosis of bacterial isolates that the pathogen is bacterium Agrobacterium tumefaciens and the isolates were recorded in the National Center For the NCBI biotechnology information, the pathogenic ability, familial range of pathogenic bacteria and the sensitivity of eucalyptus varieties were determined, and the antibacterial ability of fungal and bacterial agents used was demonstrated. High efficiency in inhibiting the growth of pathogenic bacteria in eucalyptus seedlings. Zinc oxide nanomaterial also demonstrated high efficiency in inhibition of bacteria.
The study has found the possibility of using the biological agents Trichoderma harzianum, Trichoderma atroviride and Bacillus thuringiensis in the resistance of pathogenic bacteria.
