Active Ingredient

The active ingredient in Leda 500 SC is flutriafol, a member of the triazole fungicide family. Flutriafol inhibits ergosterol synthesis, which is an essential component of fungal cell membranes. When ergosterol synthesis is inhibited, the fungal cells cannot function properly and eventually die.

• Leaf rust in wheat and barley
• Powdery mildew in wheat, barley, and canola
• Cereal mildews in wheat, barley, and other cereals
• Septoria leaf blotch in wheat and barley
• Fusarium ear blight in wheat and barley

Application Rates

The application rate of Leda 500 SC varies depending on the crop, the disease, and the stage of growth. For example, the application rate for controlling leaf rust in wheat is 0.25 L/ha, while the application rate for controlling powdery mildew in canola is 0.20 L/ha.

Application Timing

Leda 500 SC is most effective when applied to actively growing crops. It can be applied as a preventative measure or as a treatment for existing infections.

Safety Precautions

Leda 500 SC is a hazardous substance and should be handled with care. When using Leda 500 SC, wear protective clothing, including gloves, goggles, and long pants and sleeves. Avoid contact with the skin and eyes. Do not apply Leda 500 SC near waterways or wetlands.

Environmental Considerations

Leda 500 SC is toxic to aquatic organisms and should not be applied near waterways or wetlands. The fungicide can break down in the soil, but it can persist in the environment for several months.

Overall, Leda 500 SC is an effective fungicide for controlling a wide range of fungal diseases in wheat, barley, and canola. However, it is important to use the fungicide safely and responsibly to protect human health and the environment.
