Abstract | ||||
Effectiveness of two fungicides Vitavax (carboxin 37.5% + Thiram 37.5%) and Dividind (Divinoconazol) were tested for raising the resistance of several Syrian wheat cultivars against common bunt under the natural conditions and the artificial infection to the seeds and soil with spores of the causal fungi i.e., T.tritici and T.leavis. The behaviour of the two fungicides varied significantly .The treatment of Triazol (Dividind) through its highly fungal poison and making regular activity for plant for plant growth in the early stages of the plant age led to delay seed germination and seedling emergence above the soil surface by 3-5days in sowing at 3cm and 6-7 days in sowing at 6cm and its effect on seedling heights by 3-17%and reducing the surface area of the first leaf (cleoptil) by 19-43% at the first and second depths respectively, while Vitavax, had an active role in plant growth for all the previously mentioned characters. The results showed also the capacity of Dividind in raising the resistance of all the studied wheat cultivars with effectiveness varied between 91% and 87% as compared to control and between 48.9% and 35.5% as compared to Vitavax under the conditions of artificial infection to the seeds for both of the depths, respectively ,and between 97.9% and 84.5 %compared to the control and between 70% and 68.5% under the articial infection to the soil. Grain yield increased in the treatment of Dividind between 164.7% and 131.7% compared to the control and between 13.3% and 11.8% compared to Vitavax under the conditions of artificial infection to the seeds , and between 184% and 164% and between 65% and 68% under the artificial infection to the soil for both of the depths, respectively | ||||
