Summary
Copper preparations are admitted for fungal disease control. Arable crops can not be treated with copper, except for potatoes, vegetables and hops. The annual amount of copper applied is clearly restricted for individual crops to a maximum 4 kg/ha metalic copper, for apple and pears 1.5 kg/ha and for berries 2 kg/ha).
Difference
Copper application is restricted to lower quantities and in terms of crops (application rate between 1.5-4 kg pure metallic copper, arable crops excluded except potatoes). EU Regulatoin 2092/91 admits 8kg of copper till the end of 2006 and maximum 6 kg of copper afterwards: no restrictions are made in terms of crops being treated with copper preparations.
Justification
Copper is being accumulated in the soil: in order to promote sound soil fertility, any accumulation of heavy metals should be avoided.
