Evaluation of Seed Dressing Synthetic Fungicides against Complete Bunt of Wheat Caused by Tilletia foetida

Wheat is the important cereal throughout the world Complete bunt of wheat is caused by Tilletia foetida is a most prominent disease of wheat. A research field study was conducted at the Institute of Agricultural Research, Sariab Quetta. To evaluate the effectiveness of fungicides; five seed-dressing synthetic fungicides were evaluated viz., Thiophenate, Vibrax, Success, Definite, and Protocol and including control/untreated for comparison with treatments. The results revealed Vibrax showed (2.66%) level of infection followed Thiophenate (4.00%), Definite (4.66%) Protocol (5.00%) and Success (16.33%) while (8.00%) infection was observed in control/untreated group. The percentage of disease incidence was recorded as follows: Vibrax, (76.20%) Followed by Thiophenate (82.40%), Definite (86.33%) Protocol, (88.40%) and Success (91.20%) while the untreated control showed (93.40) disease incidence. Similarly, the application of seed-dressing synthetic fungicides showed the significant findings in all studied parameter and the grain yield was observed (4084.00kg/ha) maximum in treatment of Vibrax followed by Thiophenate with (3763.33kg/ha) yield, Definite, Protocol and Success treatment showed (3500.00 kg/ha), (3333.33kg/ha) and (3176.67kg/ha) respectively however control was observed with (2933.33kg/ha) yield. It was concluded that among the fungicides, Vibrax was the most effective followed by Thiophenate, particularly in controlling this seed-borne disease and recommended for seed-dressing effective management of complete bunt of wheat.
