Evaluation of antifungal activity of cinnamon essential oil on control of Fusarium solani fungi under in-vitro and in-vivo condition

In order to investigate the effect of cinnamon essential oil on control of Fusarium solani fungus an experiment was conducted as a randomized complete block design with four replication carried out in-vitro and in-vivo condition. The first experiment was effect of five concentration of cinnamon essential oil (0, 500, 1000, 1500 and 2000 ppm) on control of fungus in-vitro, and Second experiment was three application methods of essential oil (spray, priming seed and transplanting, and application with irrigation) on control of the mentioned fungus on tomato plant in-vivo condition. Cinnamon essential oil can completely controlled from the growth of the fungus at all concentrations in-vitro condition. The results showed that application of essential oil cinnamon with irrigation by 58/33 % inhibition have the maximum effect on suppress in F. solani. The highest of suppress of F. solani fungi (54/16 %) in primimg method obtained in 2000 ppm. The high percent of survive plant in application with irrigation method with 37/48 % in 1500 ppm observed. But enhance of concentration in spray method from 1500 to 2000 ppm causeed damage to plants. The obtined of result in this research, application of cinnamon essential oil with irrigation method, can be suitable way as a biological control of F. solani fungus.
