Blue Copper Fungicide from Crystal Crop Protection is a copper based fungicide containing copper oxychloride 50 WP. It is a trusted copper fungicide that controls a wide range of fungal and bacterial diseases in cereals, fruits, vegetables, and ornamental crops. When applied, it forms a protective film on plant surfaces, preventing spore germination and infection.
This copper oxychloride fungicide works by slowly releasing copper ions, which disrupt essential fungal enzymes, stopping disease spread. The fine-particle formulation ensures strong leaf adhesion, making it effective even against fungi resistant to other fungicides. Farmers use this product for both preventive and protective action, ensuring long-lasting control with fewer sprays.
It is recommended for grapes, potatoes, tomatoes, apples, mangoes, and more. For more options, explore our fungicides category. To understand copper oxychloride uses and best practices, refer to ICAR’s guidance on fungicides.
