Seed dressings against Tilletia contraversa
Experiments were conducted in Sweden to test the efficacy of three seed dressing to control Tilletia contraversa (EPPO A2 organism).
The most successful seed dressing in controlling T. contraversa was a dressing consisting of bitertanol and fuberidazole which reduced the disease by 93 %. If this seed dressing was applied to a wheat cultivar which was resistant to dwarf bunt (Tjelvar) the control efficacy rose to 99.6 %.
