Effect of Pyraclostrobin Seed Treatment On Sensitivity of Seedlings to Low Temperature Stress.

STAMINA® seed treatment fungicide, containing the active ingredient pyraclostrobin, is a new seed treatment registered by BASF for use on several agricultural crops. In addition to providing a direct antifungal activity, pyraclostrobin has been found to affect plant physiological processes in a variety of crops. Experiments were conducted to assess the protective effect of Stamina seed treatment applications against low temperature damage of seedlings at early stages. At the rates tested in laboratory, greenhouse and field research trials, Stamina demonstrated ability to protect seedlings from freeze damage at certain temperatures. An overview will be presented of Stamina’s effect on seedlings of various crops. On the crops evaluated, Stamina decreased % seedling mortality at early growth stages when compared to the non-treated control. Data suggest that in addition to providing excellent seed and seedling disease control, Stamina may provide seed treatment benefits by reducing seedling sensitivity to certain cold conditions.
