Abstract: 

The research aimed to test the efficiency of the fungicide carbendazim and isolates of the fungus Tricoderma asperillum and the bacteria Bacillus subtillis, in addition to salicylic acid, in controlling wheat root rot disease caused by some types of the genus Fusarium sp. In Lattakia, Science 2021, two wheat cultivars were used: durum (Sham 7) and aestivum (Sham 10). The seeds of both cultivars were sown in artificially prepared soil with two ferocious isolates of the fungi F. solani and F. culmorum (each separately) isolated from wheat plants. Infected with the disease in the region, the results showed that after 35-40 days of sowing the superiority of carbendazim in reducing the incidence and severity of infection with the fungus F. solani, where the percentage of reduction was 58.16% on the aestivum wheat cultivar and 54.19% on the durum wheat cultivar, followed by the treatment of the fungus T. asperillum (56.42% and 52.51%), then the treatment of B. subtillis (56.89% and 51.07%), respectively, and the differences were not significant between them, as was the case with the fungus F. culmorum, as carbendazim recorded the highest reduction rate (70.37%). And( 63.95%), respectively, followed by Tricoderma asperillum (66.86% and 61.98%), then B. subtillis (65.39% and 59.98%), respectively, and the differences were not significant. While treatment with salicylic acid did not seem effective in combating the disease.
