What is Intrinsic?

Intrinsic is the umbrella brand for all products (current and future) that are labeled for disease control and plant health. The first initiative under the Intrinsic brand is based on the active ingredient pyraclostrobin. In the future, the Intrinsic brand of products will expand to include formulation enhancers and formulation technology.

What is Plant Health?

Intrinsic brand fungicides, Lexicon® Intrinsic® brand fungicide, Insignia® SC Intrinsic brand fungicide, Honor® Intrinsic brand fungicide, Empress® Intrinsic brand fungicide and Pageant® Intrinsic brand fungicide improve plant health, not just through superior, broad-spectrum control of fungal diseases, but also through improved tolerance to stress and increased efficiency of plant processes. This enables plants to better withstand disease and a multitude of environmental stresses, resulting in improved turf and plant quality.

Intrinsic brand fungicides improve plant health through inhibition of mitochondrial respiration in both fungal diseases and plants. In fungi, inhibition of mitochondrial respiration prevents the breakdown of carbon required for production of energy to fuel fungal growth. This results in death of the fungi and is the disease control benefit.

In plants, the inhibition of mitochondrial respiration causes a cascade of positive events that can result in improved tolerance to stresses and increased efficiency of plant physiological processes. Inhibition of mitochondrial respiration by pyraclostrobin results in:

  • Less CO2 lost by the plant, resulting in more carbon available for plant growth.
  • Increased activity of nitrate reductase (NR), the enzyme that is important for making a form of nitrogen that can be used by plants. This results in more nitrogen available for plant growth.  
    • The activation of nitrate reductase increases levels of nitric oxide. Nitric oxide triggers plant defense mechanisms.  Plant defense mechanisms are important not only in defending against fungal diseases, but also bacterial and viral diseases.
    • Nitric oxide inhibits enzymes involved in the production of ethylene, a plant hormone produced in response to stress.  Ethylene can cause a plant to drop energy-containing leaves, to mature earlier than normal, and to abort flowers and seed in response to stress.
  • Increased activity of enzymes like superoxide dismutase and peroxidases that remove harmful activated oxygen species. This can result in reduced oxidative stress in response to environmental disorders, such as physiological leaf spot, ozone damage, cold stress, and heat stress.
