Mode of Action

Metiram functions as a preventative fungicide, effectively killing fungal spores immediately after germination and before they penetrate the plant tissue. It achieves this by interfering with amino acid synthesis within fungal cells, stopping their growth and subsequent infection.

Notably, Metiram is most effective as a protective measure. It will not control fungal infections already established within plant tissues, emphasizing the importance of early and regular preventive treatments.

Advantages and Compatibility

• Preventive Action: Forms a strong protective layer to prevent fungal spore germination.

• IPM Friendly: Compatible with integrated pest management programs due to its low impact on beneficial insects.

• Compatibility: Can be mixed safely with most insecticides and fungicides. However, local compatibility checks with specific products are recommended.
