Abstract: Hassan, S.M.A. and A.A.A. Al-Jbory. 2023. A Study of the Effect of the Interaction Between Covered Smut Disease and Seed Galls Nematode on the Susceptibility of Wheat to Infection with the Two Diseases. Arab Journal of Plant Protection, 41(4): 406-411. https://doi.org/10.22268/AJPP-41.4.406411 A study was conducted to evaluate pathogenicity of the combined inoculum of the cover smut disease caused by the fungal pathogen Tilletia spp. and seed galls caused by the nematode Anguina tritici on two wheat cvs. Research 22 and Ebaa 96. The infection rate of covered smut increased significantly as compared to the infection rate of the treatment inoculated with only the fungal Tilletia spp. spores. The infection rate of covered smut in the treatment inoculated with the mixed inoculum reached 61.11 and 52.33%, for both wheat cvs., respectively, compared to the treatment of inoculation with only the fungal causative agent of covered smut, reaching 38.66 and 43.33%, respectively. The same was not obtained for the seed galls incidence, as the highest infection rate was recorded with the treatment of single contamination with A. tritici nematode inoculum of both wheat cultivars Abaa 96 and Research 22, which reached 29.11 and 26.33%, respectively, with a significant difference from the treatment of the combined inoculum (Tilletia spp. + A. tritici), which reached 18.22 and 9.66%, respectively. In addition, the reduction in the studied growth parameters and yield increased, and the plant height, dry biological weight and spike weight decreased when both wheat varieties were inoculated with the combined inoculum. Keywords: Covered smut, Tillitia spp., Anguina tritici, wheat.
