• Trade name: Signum
• Active ingredients: Boscalid and Pyraclostrobin
• Fungicide class: Group SDHI and Group C3 (FRAC) fungicide

Mode of Action:

Signum is a systemic fungicide that works by two different modes of action. Boscalid is a succinate dehydrogenase inhibitor (SDHI) fungicide that disrupts the fungus's energy production. Pyraclostrobin is a strobilurin fungicide that inhibits energy production in the fungus. This combination of modes of action makes Signum very effective against a wide range of fungal diseases.

Application:

Signum can be applied to a variety of crops, including apples, grapes, tomatoes, peppers, potatoes, and vegetables. It can be applied pre-emergence or post-emergence, but it is most effective when applied preventatively. Signum can be applied using a variety of application methods, including ground spraying, aerial spraying, and chemigation.

Precautions:

• Signum is toxic to fish and other aquatic life. Do not apply Signum to areas where it may run off into water bodies.
• Signum can be harmful to non-target plants. Avoid applying Signum to areas where non-target plants are growing.
• Signum is a residual fungicide, so it can persist in the soil for several weeks. Do not plant crops that are sensitive to Signum within 3 to 6 weeks of application.

Always follow the label directions carefully when using Signum fungicide to ensure safe and effective use.

Additional Information:

• Signum is a relatively new fungicide, so there is less resistance to it than other fungicides.

  • Apple scab
  • Powdery mildew

• Signum is a systemic fungicide, which means that it is absorbed by the plant and translocated to the growing points. This makes it very effective at controlling fungal diseases.

Signum is a valuable tool for farmers and other land managers who need to control fungal diseases in a variety of crops. It is important to use Signum according to the label directions to ensure safe and effective use.
