Introduction Of Polyram Fungicide

Fungal diseases are among the most damaging problems farmers face, affecting yield quality and quantity. Polyram Fungicide has become a trusted solution for growers seeking reliable, broad-spectrum disease control. Manufactured by UPL Limited, this fungicide offers preventive protection against a wide range of fungal pathogens and helps farmers maintain healthier, more productive crops.

Let’s explore the key features, benefits, recommended crops, and usage details of Polyram Fungicide to help you get the best results.

What is Polyram Fungicide?

Polyram is a broad-spectrum, contact fungicide containing Metiram 70% WG (Wettable Granules) as the active ingredient. It belongs to the dithiocarbamate group of fungicides and is known for its protective action against multiple fungal diseases.

This fungicide forms a uniform protective film on the plant surface, preventing fungal spores from germinating. Because it works externally and does not enter the plant system, it is considered a multi-site contact fungicide, making it highly effective in resistance management programs.

Mode of Action of Polyram

Polyram acts by inhibiting multiple enzyme systems in fungal spores during their germination and penetration phases. The multi-site action disrupts various metabolic processes, preventing fungi from establishing infection in plant tissues.
