Technical Advantages
COBBER S has been developed to improve the performance of copper-based applications under field conditions. Its consistent, sub-micron particle size allows better distribution on leaves, stems and target plant surfaces, increasing the contact area and improving disease protection.
As a multisite contact copper formulation, COBBER S acts externally on the plant surface, helping reduce the development and spread of fungal and bacterial diseases. This makes it a valuable tool within integrated crop management programs where preventive protection, copper nutrition and crop safety are priorities.
The liquid formulation is designed to readily mix in water and remain suspended longer than conventional liquid formulations, supporting homogeneous application and consistent field performance.
