Cyprodinil

Type: Fungicide

Mode of Action: Inhibiting the biosynthesis of methionine

Common Product Names: Switch & Vangard

What is it?

Cyprodinil is a systemic fungicide that belongs to the anilinopyrimidine class of chemicals. It is highly effective against a range of fungal diseases, including Botrytis (gray mold), Alternaria, and scab in various fruit, vegetable, and ornamental crops. Cyprodinil is often used in integrated pest management (IPM) programs because of its ability to prevent disease development and reduce the reliance on other fungicides. This active ingredient is commonly applied as a foliar spray and is absorbed by the plant's tissue, providing protective and curative effects. Cyprodinil is known for its efficacy in cool and wet conditions, which are often conducive to fungal disease development.

How does it work?

Cyprodinil works by disrupting the normal functioning of the fungal cell. Once applied, it is absorbed by the plant and translocated within the tissues. The fungicide inhibits the production of methionine, a vital amino acid, by blocking the activity of key enzymes in the fungus. This disruption in protein synthesis leads to the cessation of fungal growth and reproduction.

Benefits

  • Curative and Preventative Action: Cyprodinil offers both curative and preventative properties, making it effective at stopping an existing infection and protecting against future outbreaks.
  • Systemic Action: Its ability to be absorbed and translocated within the plant ensures comprehensive protection, reaching areas that may not be directly sprayed.
  • Effective in Cool, Wet Conditions: Cyprodinil remains effective in conditions that are typically challenging for other fungicides, providing reliable disease control even in less-than-ideal weather.
  • Long-Lasting Protection: It provides residual control, offering extended protection after application, which reduces the frequency of treatments.
