Mefenoxam

Type: Fungicide

Mode of Action: Inhibiting RNA polymerase activity in the fungal cells

Common Product Names: Ridomil Gold & Ultra Flourish

What is it?

Mefenoxam is a systemic fungicide belonging to the phenylamide class of chemicals. It is widely used in agricultural and horticultural settings to manage diseases caused by Oomycetes fungi, such as Pythium, Phytophthora, and downy mildew. Its systemic nature allows it to be absorbed and translocated within the plant, providing protective and curative action against a wide range of soil and foliar pathogens.

How does it work?

Mefenoxam targets the ribonucleic acid (RNA) polymerase in fungal cells, specifically inhibiting their ability to produce RNA. This inhibition disrupts the normal functioning of the fungal cells, stopping their growth and preventing the synthesis of essential proteins. As a result, the fungal cells die, and the spread of the disease is controlled.

Benefits

  • Systemic Action: As a systemic fungicide, Mefenoxam is absorbed by the plant and translocated to all parts, providing comprehensive protection.
  • Preventative and Curative: Mefenoxam can be used both preventatively and curatively, making it a versatile tool in disease management programs.
  • Long-lasting Residual Effect: Mefenoxam provides a long-lasting residual effect, offering extended protection against fungal pathogens.
  • Quick Action: Results can often be seen relatively quickly, with noticeable disease control within a few days of application.
