Signum Fungicide – A Complete Guide for Superior Disease Control

Introduction of Signum Fungicide

Protecting crops from destructive fungal diseases is essential for maintaining high yields and premium-quality produce. Signum Fungicide, a highly trusted product in modern agriculture, delivers broad-spectrum disease control with long-lasting effectiveness. Known for its unique combination chemistry, Signum ensures stronger plants, cleaner fields, and healthier harvests. In this blog, we’ll explore what Signum Fungicide is, how it works, its benefits, recommended application doses, suitable crops, and more.

What Is Signum Fungicide?

Signum is an advanced, dual-mode fungicide widely used across horticultural and field crops. It contains:

• Boscalid (26.7% WG) – A powerful SDHI fungicide
  
• Pyraclostrobin (6.7% WG) – A premium QoI (strobilurin) fungicide
  

This combination provides both protective and curative activity, offering one of the broadest spectrums of disease control. Signum is especially valued for its ability to manage multiple pathogens simultaneously while improving plant vigor and overall crop health.

How Signum Fungicide Works

The unique synergy of Boscalid and Pyraclostrobin makes Signum exceptionally effective:

1. Boscalid: Targeted Interference

Boscalid inhibits fungal respiration by blocking succinate dehydrogenase (SDH). This stops energy production in fungal cells, ultimately preventing growth and sporulation.

2. Pyraclostrobin: Broad Action & Plant Health Benefits

Pyraclostrobin halts spore germination and prevents the spread of the fungus. Additionally, it enhances physiological processes in plants—commonly referred to as the AgCelence® effect—leading to improved stress tolerance, greener foliage, and better yield quality.

Together, these two molecules provide preventive, curative, and long-lasting protection.
