  • عنوان البحث : EFFICIENCY OF SOME BIOLOGICAL CONTROL AGENTS AND PLANT EXTRACTS AGAINST FUSARIUM SOLANI CAUSING AGENT OF DAMPING OFF DISEASE

    ملخص البحث :

    The aim of this study was to isolate and diagnose the causing of Damping off Disease on Tomato in the Babylon governorate-Iraq. And evaluate the effectiveness of Trichoderma harzianum and some plant extracts in the control of the pathogen. The results of isolating the fungus from the affected plant parts of the tomato seedlings revealed the emergence of 3 isolates of Fusarium solani. The results of the test of pathogenicity showed that all isolates of the fungus had a pathogenic ability. The results showed that T. harzianum was effective against of the F. solani and with a high inhibitory rate. The bacteria Bacillus thuringiensis were low effective inhibition of pathogen growth. The water extract of the leaves of the Conocarpus lancifolius and the Xanthium strumarium (Rough cocklebur)(5, 10 and 15%) was effective in the fungus F. solani (Fs3) and with a significant superiority of the Rough cocklebur extract at 15% concentration. The results showed that the agents used in the study provided good protection for tomato seed and seedlings from infection. The treatment of interference between T. harzianum and Bacteria and the Rough cocklebur extract was protected the seeds and improved their germination to be 88.88% compared to the germination rate of the pathogen, which had a germination rate of 33.33%. The integrated treatment between the T. harzianum, B. thuringiensis and Rough cocklebur extract was superior in reducing the disease incidence and severity of infection into 25.92% and 13.33% respectively and close to the treatment of chemical fungicide Beltanol, which was the 14.81 and 8.14%, respectively. And improved the parameters of …

  • عنوان البحث : Control of damping-off and root rot diseases of Acacia tree using some biological control agents and plant extracts

    ملخص البحث :

    The study included the isolation and diagnosis of the associated fungi to dampingoff and the root rot disease of the Acacia plants and evaluating the effectiveness of some biological agents in controlling the disease in vitro. The results of isolation and diagnosis from the infected roots of Acacia plant showed the presence of the two pathogenic fungi (Rhizoctonia solani and Fusarium solani), which appeared frequently in all samples brought from some nurseries in Babylon province. The isolates of two pathogenic fungi (R. solani and F. solani) affected the germination of Acacia seeds which led to occurring a significant excelling through raising the intensity of the infection with two pathogenic fungi (R. solani and F. solani) which amounted to 83.33 and 41.66%, respectively, compared to the control treatment, in which the intensity of the infection amounted to zero. The two fungi had also significantly reduced the dry and …

  • عنوان البحث : EFFICIENCY OF SOME BIOLOGICAL FACTORS AND PLANT EXTRACTAS AGAINST THE FUNGUS RHIZOCTONIA SOLANI KUHN REASONED ROOT ROT DISEASE OF SOYBEAN

    ملخص البحث :

    The Present study aimed to investigate the isolation and diagnosis of the Soybean roots rotting causative agent with the evaluation of some agents of bioprotection and its protection efficiency under the Laboratory and the Lath house environment. Results indicated that isolation from efected Soybean roots the presence of Rhizoctonia solani Fungus which is presented in recurrent condition from all samples that brought Karbala province fields. The fungus isolates referred that the pathogenic isolate of R. solani showed of Soybean seeds cultivation which was significantly surpassed for increasing the pathogen city severity to 100% as compared to the control which was zero% 0, I n addition the pathogenic fungus led to significant reduction of lengths with the wet and dry weights of the greenish and root parts of the plant. Antagonistic ability of Azotobacter chroococcum bacteria indicated a high efficiency inhibition of …
